AA038726

Anaheim, CA—September 30—2020—Process and plant engineers will find the high-temperature, high-pressure CSX2 Conductivity Analyzer from Electro-Chemical Devices (ECD) helps ensure boiler performance while minimizing maintenance, repairs and extending life in a wide range of critical industrial applications requiring water heating and steam.

The versatile, go-almost-anywhere high-temperature, high-pressure CSX2 Conductivity Analyzer is designed for service to 392°F (200°C) and 250 psig, or 212°F (100°C) and 400 psig. This insertion style 0.75-inch MNPT, 316 stainless steel sensor has PEEK insulators and is available with or without an integral signal conditioner.

The Model CSX2 Conductivity Analyzer measures conductivity over a wide range from 1.0 μS to 50 mS. For accurate measurement and dependable performance, it features built-in sensor temperature compensation that adjusts automatically over installed temperatures from 0>- 392>°F (0>-200>°C).

Hot water is a severe environment for any elastomer. The Model CSX2’s front EPR O-ring seals bear the brunt of the chemical attack, allowing the back seals to remain relatively unaffected. This redundant design increases the reliability of the CSX2, dramatically increasing the usable lifetime of the sensor in these harsh applications.

The Model CSX2’s aluminum junction box is mounted on the rear of the sensor, containing a terminal block and optional signal conditioner. It is an ideal choice for boiler control applications, blowdown control, condensate monitoring, leak detection on heat exchangers and steam purity measurements.

The optional signal conditioner amplifies the conductivity signal, allowing noise-free transmission for hundreds of feet. A wide range of signal conditioners are available for the CSX2 sensor to optimize the conductivity measurement at specific ranges. The ECD Model LQ800 Multi-Channel Controller or the T80 Transmitter have a user specified signal conditioner that is mounted inside the CSX2 instrument or optionally in a remote junction box.

The measurement of conductivity and resistivity in liquid water-based solutions is an essential requirement in a wide range of industrial processes. Conductivity and resistivity measure the electrical conductivity of a solution, which correlates to the purity of the water or the amount of dissolved ions in the liquid.

Accurate, reliable conductivity data is important when either recycling water for re-use within the plant to protect sensitive equipment from internal corrosion (scale) and/or when discharging water from the plant into wastewater treatment systems. The data helps ensure the effluent meets local, state and federal water quality standards to avoid plant shutdowns and costly fines.

Family of Disinfection Analyzers Helps Prevent Virus and Bacteria Spread Via Water & Wastewater

Anaheim, CA—October 27—2020—Engineers and technicians working to prevent the spread of viruses and bacteria at municipal as well as industrial water and wastewater treatment plants will want to learn more about the highly accurate, reliable sensing technologies available with the Family of Disinfection Analyzers from Electro-Chemical Devices (ECD).

Relying on reagentless amperometric chlorine, hydrogen peroxide and peracetic acid sensing technologies, ECD’s panel-mounted disinfection analyzers support a wide range of water purification and treatment applications. Their highly intelligent, full-featured transmitters are conveniently located on the front panel with plug-and-play capability that takes technicians only minutes to install: simply mount, plumb, plug-in and turn-on.

The FC80 Free Chlorine, TC80 Total Chlorine, HP80 Hydrogen Peroxide and PA80 Peracetic Acid analyzers all come pre-calibrated from the factory in a choice of multiple ranges. They monitor the effectiveness of water treatment systems and validate that they are doing their job to help prevent the spread of viruses, bacteria and other dangerous pathogens in drinking water, rinse water, wash-down water, cooling water and wastewater effluent.

In addition, their reagentless sensor design reduces the total lifecycle costs of these analyzers. The cost of reagents can be a considerable expense over the life of an analyzer and technicians must also regularly monitor reagent consumption and then refill. The inactive reagents at their end-of-life are toxic materials, which require special handling with higher disposal costs.

The FC80 Free Chlorine Analyzer is designed to monitor free chlorine (residual chlorine) in municipal drinking water, industrial cooling and rinse water, wastewater or other fresh water samples containing chlorine. It is available in two optional configurations: either a hi-range of 0.05-20 ppm or a low-range of 0.01 to 5.00 ppm unit. It is compliant with EPA Method 334.0

The TC80 Total Chlorine Analyzer monitors total chlorine in drinking water, industrial cooling and rinse water, wastewater or other fresh water samples containing chlorine in the range of 0-20 ppm. Its versatile three-electrode amperometric sensor design also can be specified to measure all chlorine species in the water, combining chlorine and free chlorine in a high range of 0.05 to 20 ppm or a low range of 0.005 to 2.000 ppm.

The PA80 Analyzer monitors peracetic acid (PAA) in the food, beverage, medical and pharmaceutical industries, as well as in industrial process cooling towers and municipal wastewater treatment. Peracetic acid is a colorless liquid with a characteristic pungent odor similar to vinegar. PAA is a strong oxidizer, stronger than either chlorine or chlorine dioxide. It is available in a choice of three ranges: 0 to 20 ppm or 0 to 200 ppm and 0 to 2000 ppm. PAA is

The HP80 Analyzer is designed to monitor hydrogen peroxide (H2O2) in water in two ranges: either 0 to 200 ppm or 0-20.0% H2O2. HP is widely used in the pulp/paper industry as a bleaching agent, as an oxidizer to remove metals from well water, as a disinfectant for industrial cooling water towers and in municipal wastewater treatment effluent. HP is a colorless liquid that in high concentrations gives off an irritating acidic odor. It is a strong oxidizer, stronger than either chlorine or chlorine dioxide.

No matter the water treatment or purification application, there is a solution with the ECD family of disinfection analyzers. They’re all designed for accuracy, reliability, long-life and low cost of ownership with their reagentless, low-maintenance amperometric sensors and intelligent transmitter with two 4-20 mA outputs, three alarm relays and MODBUS RTU.

Enhancing Wastewater Ammonia Treatment With Economical CA-6 Colorimetric Analyzer

Anaheim, CA—August 25—2020—Engineers at municipal wastewater treatment plants tasked with the removal of ammonia will find the versatile CA-6 Colorimetric Ammonia Analyzer from Electro-Chemical Devices (ECD) helps them protect water quality with confidence prior to releasing effluent into re-use systems, groundwater recharge basins and surface water systems.

Exposure to ammonia over time is toxic to aquatic life. The U.S. Environmental Protection Agency (EPA) recommends a limit of 0.02 ppm as NH3 in freshwater or marine environments. Total ammonia levels, at this limit, can range from 160 ppm at a pH6 level and at temperature of 41°F (5°C) to 0.06 ppm at a pH9 level and temperature of 77°F (25°C).

Wastewater treatment plants frequently use the Nitrification method to remove ammonia. Nitrification is a two-step process for removing ammonia from wastewater using two different types of autotrophic bacteria that oxidize ammonia to nitrite (nitrosomonas) and then oxidize nitrite to nitrate (nitrobacter).

The ECD CA-6 Ammonia Analyzers help plant technicians determine the effectiveness of the treatment process prior to effluent discharge. With its adjustable cycle time, the CA-6 Ammonia Analyzer reduces the cost of treatment by minimizing the use of consumable reagents while still getting the job done effectively. Technician time is reduced as well, freeing staff for other important tasks.

The CA-6 Analyzer is an on-line sequential sampling analyzer. It automatically performs a controlled sequence of sampling, analysis and then results processing is performed and repeated using colorimetric methods with a reagent. The colorimetric method of water analysis relies on an LED light source and a heated colorimetric cell, which has been designed for measuring trace amounts of Ammonia in water.

The versatile CA-6 Colorimetric Analyzer can be configured to measure Ammonia or a wide range of other substances with a choice of multiple parameters: ppb, ppm and mg/L. It measures Ammonia over a wide range from trace 0 to 50 mg/L. Three separate Ammonia measurement ranges are available: 0 to 1.0 mg/L, 0 to 10 mg/L and 0 to 50 mg/L.

The CA-6 Colorimeters make two measurements during an analysis cycle. The first measurement is of the raw sample which sets the base line for the compensation of color, turbidity and optical characteristics of the cell. The second measurement occurs after the color forming reagents have been added to the sample, mixed and adequate time has passed to allow for color formation. The concentration is calculated using the difference between the two absorbance measurements and the stored calibration information in the analyzer.

The CA-6 Colorimetric Analyzer is equipped with a graphic touchscreen interface showing measured values and status information. It provides users with easy access to menus and functions in multiple languages. There is an integrated data logger onboard with USB download capability for history tracking.

The display’s home screen shows the measured parameter, the status, % reagent volumes, time and Menu choices. The on screen HELP menu includes information on Start Up, Shut Down, Start/Stop Commands, Calibration, Function List, Programing, Maintenance and Troubleshoo1ng.

Outputs provided with the CA-6 Analyzer include two 4-20 mA outputs for measured data, and it also includes a Modbus compatible RS485 RTU. Four programmable SPDT relays are available to provide alarm capability.

The CA-6 Colorimetric Analyzers is designed with two compartments that separate critical electronics from the wet process. The standard model is recommended for indoor use and rated NEMA IP54 for dust and water ingress. The operating temperature range of the CA-6 Analyzer is 41 to 113 °F (5 to 45 °C).

Self-Cleaning Ultra Violet Family of Water Analyzers Ready to Go Right Out of the Box with No Reagents

Ideal for Drinking Water Disinfection and Wastewater Treatment

Anaheim, CA—July 24, 2019—With their advanced ultra violet absorption sensing technology, the new family of UV-6 Analyzers from Electro-Chemical Devices (ECD) helps treatment plant engineers and technicians assure the safety of surface and ground water supplies, drinking water disinfection and protect the environment from untreated wastewater effluent.

Relying on their sophisticated UV absorption correlation technology, the ECD UV-6 Analyzers are designed to monitor five separate parameters over a wide range of values.  They accurately measure via their spectroscopic sensor at a 254 nm wavelength with correlation algorithms the presence of ammonia, nitrate chemical oxygen demand (COD), biological oxygen (BOD) or total organic carbon (TOC).

The analyses of these pollutants are based on the measurement of UV absorption in a collected sample. Ammonia measurement is available in two ranges: either 0 to 10 ppm or 0 to 1000 ppm. Nitrate measurement is available in three ranges: 0 to 30 mg/L, 0 to 100 mg/L or 0 to 250 mg/L.  Measurement of COD, BOD and TOC is available in two ranges:  0 to 200 mg/L or 0 to 20,000 mg/L

The absorbance of the solution or gas is measured though a quartz flow cell at a specific wavelength using a long-life Xenon light source and photo-detectors. The absorbance is related to the sample concentration according to the Beer-Lambert Law, which relates the attenuation of light to the properties of the solution through which a projected light is traveling.

The UV-6 Analyzers come pre-calibrated from the ECD factory, which makes them easy to install and start up.  There’s no complicated assembly or calibration solutions, no special tooling needed or lengthy technician installation training.  Simply remove the analyzer from the packaging, connect the sample, waste and cleaning lines, plug-in and power up the unit.  Wall mounting hardware is provided standard, and an optional benchtop stand is also available.

This family of easy-to-use analyzers greatly reduces technician maintenance time and consumables expenses.  The design of the UV-6 features a built-in spray cleaning system that keeps the light source and sensor cell free from algae growth and sticky particles to ensure accuracy.  Best of all there are no costly reagents required, which also must be disposed of properly to prevent environmental contamination.

Data logging is provided via RS232 communications.  Four alarm relays are included, which are normally open, 5 Amp at at 250 VAC, along with a single 4-20 mA output with 12-bit resolution.  Choose from multiple power supply options: 110-130 VAC or 220-240 VAC /30VA / 50-60Hz, or 12-15 VDC /4A.

Electro-Chemical Devices introduces CA-6 Colorimetric copper analyzer

Process and plant engineers treating municipal drinking water or industrial wastewater who need to monitor, remediate or remove harsh Iron (Fe) can use the precision CA-6 Colorimetric Copper Analyzer from  Electro-Chemical Devices (ECD) with the goal to achieve desired water quality levels and protect water resources.

With its adjustable cycle time that minimizes reagent use and maintenance, the CA-6 Colorimetric Analyzer is a solution to iron or other undesirable minerals. Iron ores are among the earth’s most common elements.  The human body requires iron for good health, but too much iron causes health problems as well.  While for industrial plant applications, too much iron can be a sign of process impurities, pipe corrosion or discharge effluent issues.

The U.S. Environmental Protection Agency (EPA) through its National Secondary Drinking Water Regulations (NSDWRs) recommends that Fe levels not exceed 0.3 mg/L.  The EPA’s NSDWRs are non-enforceable guidelines for contaminants that may cause cosmetic effects (skin or tooth discoloration) or aesthetic effects (taste, odor, or color).

ECD’s CA-6 Iron Analyzer is an on-line sequential sampling analyzer. It automatically performs a controlled sequence of sampling, analysis and then results processing is performed and repeated using colorimetric methods with a ferrozine reagent. The colorimetric method of water analysis relies on an LED light source and a heated colorimetric cell, which has been designed for measuring trace amounts of Fe in water.

The CA-6 Colorimetric Analyzer measures Fe using the differential photometric absorbance method.  In an acid buffered solution, ferrozine and iron react to form a purple colored complex measured at 572 nm.  The light absorption intensity is proportional to the iron concentration level in the water sample.

The CA-6 Colorimetric Analyzer can be configured to measure iron or a range of other substances with a choice of multiple parameters:  ppb, ppm and mg/L.  It measures iron over a wide range from trace ug/L to 10 mg/L.  Three separate measurement ranges are available depending on the chosen cell size: 2 to 250 ppb (26 mm cell), 9 to 500 ppb (16 mm cell) and up to 10 mg/L with an internal dilution module.

The CA-6 Iron Analyzer consumes its ferrozine reagent at 2.5L (0.66 US.gal) for the 16 mm cell and 5L (1.32 US gal) for the 26 mm cell.

The CA-6 Colorimetric Analyzer is equipped with a graphic touchscreen interface showing measured values and status information. It provides users with easy access to menus and functions in multiple languages. There is an integrated data logger onboard with USB download capability for history tracking.

Outputs provided with the CA-6 Analyzer include two 4-20 mA outputs for measured data, and it also includes a Modbus compatible RS485 RTU.  Four programmable SPDT relays are available to provide alarm capability.

ECO Magazine featured TR80 Turbidity Analyzer

New Next-Gen Intelligent Optical Sensor Delivers Precise Turbidity Measurement

 

Water treatment engineers tasked with assuring reliable potable water treatment from ground or surface sources and storage reservoirs as well as those responsible for suspended solids in municipal or industrial wastewater effluent will find the smart TR80 Turbidity Analyzer from Electro-Chemical Devices (ECD), offers them a flexible and economical solution to safe drinking water or treated effluent suitable for release or re-use.

The new, versatile Triton TR80 Turbidity Analyzer features a highly-effective nephelometric turbidity sensor designed for use in water and wastewater. Turbidity, the cloudiness or haziness of a water sample, is caused by particles or solids suspended in the water, typically clay and silt, or fecal matter, or various industrial wastes. As bacteria and viruses can be attached to these particles and solids, turbidity analysis has become a critical indicator of overall water quality.

The advanced Triton TR80 Analyzer relies on the proven optical method with digital communications for determining turbidity and/or suspended solids. A light beam provided by the LED is directed into the sample where it is scattered by the particles or suspended particles in the water. The amount of scattering depends on the amount of impure material in the water, the wavelength of the light used and the size and composition of the particles or suspended solids.

Employing a long-life near infrared LED light source and the 90-degree scattered light method of detection in accordance with ISO 7027/EN 27027, assures users of highly accurate turbidity measurement values under standardized and comparable conditions. The 90-degree scattered light detection method is the industry’s most common sensor design for turbidity. ECD’s powerful sensor design is advantageous in that it provide high sensitivity for turbid conditions over the entire measurement sample range.

Next-Gen Optical Turbidity Analyzer

The versatile TR80 Sensor can be configured for both turbidity and/or Suspended Solids and connects via digital communications with the ECD T80 Transmitter or the ECD LQ800 Multi-Channel Controller for plug-n-play operation. Multiple standard factory pre-calibrated sensor ranges, as well as custom ranges upon request, are available including: 1 senor at 0.00-1000 mg/l or 0-1000 NTU, FNU; 3 sensors at 0.00-5000 or greater mg/l or 0-4000 NTU, FNU, ppm, mg/L; and 4 sensors at 0.00-30 mg/l or 0-30 NTU, FNU.

For ease of use and low life-cycle maintenance costs, The TR80 Turbidity Analyzer includes a simple optical configuration with an automated cleaning wiper to prevent the build-up of algae, oils and other contaminants. The wiper is pre-set at the factory to clean the sensor lens at regular intervals frequent enough to assure accurate measurement and reduce the need for technician manual inspection and cleaning, which over this instrument’s long life can add up to a significant operational cost savings.

The rugged TR80 Analyzer is available in four configurations: flow-through-cell, de-bubbler flow cell, immersion assembly and valve-retractable unit. Three choices of standard six-wire electrical connections are available with cable assemblies of either 10-ft (3.0 m), 20-ft (6.1 m) or 30-ft (9.1 m). It is designed for freezing to frying conditions operating from 23 to 122°F (5 to 50°C).

IPP&T Features TOC analyzer

ECD TOC analyzer monitors glycol at industrial plants

Those responsible for managing wastewater run-off treatment from commercial or private airports, aerospace industry facilities, military bases and chemical processing plants will want to learn more about how the advanced Total Organic Carbon (TOC) Analyzer from Electro-Chemical Devices (ECD) helps them manage ethylene glycol and other waste streams to safeguard water resources.

While primarily used for industrial process and manufacturing applications, ethylene glycol is key component in de-icing solutions for aircraft and airport runways during cold winter months. It is also found in automotive anti-freeze, coolant and brake fluids.

With its non-dispersive infrared (NDIR) detection technology, ECD’s TOC Analyzer helps pollution control engineers know that their wastewater treatment job is complete and that treated water effluent is ready for re-use or release.  Installing this analyzer helps facilities meet regulatory compliance requirements for treated facility storm or plant water with high confidence.

TOC analyzers measure the carbon in the organic matter that is nearly always present in water, whether it is surface water, ground water or treated industrial wastewater. Measuring TOC levels can be an important process variable when monitoring and controlling organic matter in water with residual glycol and other hydrocarbon pollutants.

There are many Industries and applications for ECD’s TOC Analyzer.  They include drinking water, feed and cooling water in manufacturing, facility runoff water and wastewater being discharged to the environment where an accurate and reliable TOC measurement is required to protect the water supply.

ECD’s TOC Analyzer is a full-featured instrument that utilizes the UV persulfate oxidation sensing method, which detects generated carbon dioxide (CO2) using its highly stable NDIR detector for analysis.   This method and the analyzer conform to: US EPA, DIN, CE, ASTM and NAMUR regulations, as well as ISO.

ECD’s TOC Analyzer is simple to use: the water sample is first acidified and then sparged to remove inorganic carbon.  The remaining liquid is mixed with sodium persulfate and digested by two high-performance reactors.  The resulting CO2 is then stripped from the liquid and, after drying, its concentration is measured by the NDIR analyzer. The analyzer measures TOC’s ranging from 0-5 mg/L to 20,000 mg/L, indicating the presence of glycol.

The advanced design of ECD’s TOC Analyzer features a valve-free sample line, which largely eliminates blockages. The analyzer’s auto clean, auto-calibration and auto-validation functions guarantee correct, reliable values that can be reproduced at any time without the need for manual intervention.

In comparison to conventional analyzers where the flow is controlled by a glass tube rotameter, the carrier gas flow with the ECD TOC Analyzer is controlled digitally. The flow is monitored via built-in smart diagnostics and if an abnormal value is detected, the analyzer stops automatically and displays a warning alert.

The rugged ECD TOC Analyzer is housed in a dual compartment enclosure.  The water sample components are in one compartment, and the electronics are located in a second compartment for safety and highly reliable operation.  The analyzer compartment is rated IP54, NEMA 3, and conforms to EN610004-2, EN610004-4, C46-022, EN 55022 and EN 61326.

The highly intuitive TOC Analyzer features a user touchscreen display located on the front of the analyzer.  All output/input data, status information, alarms and fault conditions are shown on the display.  Simply pressing the touchscreen buttons provides access to commands and settings.  The system is password protected for security.

TOCs in wastewater are regulated by the US EPA, state and local water quality standards. Many other industries rely on TOC measurement for analysis of wastewater prior to discharge. In addition, the power generation industries rely on TOC measurements for water quality concerning cooling water, condensate and boiler feed water.

Processwest Featured TR80-Turbidity-Analyzer

Intelligent optical sensor delivers precise turbidity measurement

Water treatment engineers tasked with assuring reliable potable water treatment from ground or surface sources and storage reservoirs as well as those responsible for suspended solids in municipal or industrial wastewater effluent will find the smart TR80 Turbidity Analyzer from Electro-Chemical Devices (ECD), offers them a flexible and economical solution to safe drinking water or treated effluent suitable for release or re-use.

The new, versatile Triton TR80 Turbidity Analyzer features a highly-effective nephelometric turbidity sensor designed for use in water and wastewater. Turbidity, the cloudiness or haziness of a water sample, is caused by particles or solids suspended in the water, typically clay and silt, or fecal matter, or various industrial wastes. As bacteria and viruses can be attached to these particles and solids, turbidity analysis has become a critical indicator of overall water quality.

The advanced Triton TR80 Analyzer relies on the proven optical method with digital communications for determining turbidity and/or suspended solids. A light beam provided by the LED is directed into the sample where it is scattered by the particles or suspended particles in the water. The amount of scattering depends on the amount of impure material in the water, the wavelength of the light used and the size and composition of the particles or suspended solids.

Employing a long-life near infrared LED light source and the 90-degree scattered light method of detection in accordance with ISO 7027/EN 27027, assures users of highly accurate turbidity measurement values under standardized and comparable conditions. The 90-degree scattered light detection method is the industry’s most common sensor design for turbidity. ECD’s powerful sensor design is advantageous in that it provide high sensitivity for turbid conditions over the entire measurement sample range.

The versatile TR80 Sensor can be configured for both turbidity and/or Suspended Solids and connects via digital communications with the ECD T80 Transmitter or the ECD LQ800 Multi-Channel Controller for plug-n-play operation.  Multiple standard factory pre-calibrated sensor ranges, as well as custom ranges upon request, are available including: 1 sensor at 0.00-1000 mg/l or 0-1000 NTU, FNU; 3 sensors at 0.00-5000 or greater mg/l or 0-4000 NTU, FNU, ppm, mg/L; and 4 sensors at 0.00-30 mg/l or 0-30 NTU, FNU.

For ease of use and low life-cycle maintenance costs, The TR80 Turbidity Analyzer includes a simple optical configuration with an automated cleaning wiper to prevent the build-up of algae, oils and other contaminants.  The wiper is pre-set at the factory to clean the sensor lens at regular intervals frequent enough to assure accurate measurement and reduce the need for technician manual inspection and cleaning, which over this instrument’s long life can add up to a significant operational cost savings.

The rugged TR80 Analyzer is available in four configurations: flow-through-cell, de-bubbler flow cell, immersion assembly and valve-retractable unit. Three choices of standard six-wire electrical connections are available with cable assemblies of either 10-ft (3 m), 20-ft (6.1 m) or 30-ft (9.1 m). It is designed for freezing to frying conditions operating from 23 to 122°F (5 to 50°C).  It can take the pressure too, with a choice of multiple flow cell configurations available that withstand a range of up to 50 psi (3.5 bar maximum).  The sensor body features wetted materials of CPVC or optionally POLYPRO polypropylene material.

Analyzer Plays Important Role in Mine Wastewater Cyanide Treatment

By Josue Nduwa, Development Metallurgist, Oceana Gold, Haile Operation, and Anil Isaac, Applications Engineer, Electro-Chemical Devices, Inc. 

Cyanide (CN) is commonly utilized in multiple industrial processes in the global mining, metals, chemical, electronics, steel, pharmaceutical and other industries. Five processes have been said to account for most of the CN wastewater streams, and they include: refining of gold and other metal ores, metal plating, case hardening of steel, neutralizing of process acid “pickle scum” and scrubbing of stack gases from blast and process industry gas furnaces. 

Well-known for its toxic properties, CN is a carefully regulated substance by environmental, health and safety agencies around the globe to protect workers, surrounding communities and local water supplies. When used in the gold mining industry in the form of Sodium Cyanide (NaCN) or Calcium Cyanide (CaCN2), the CN compound of choice is mixed with water in a carefully controlled process. Prior to extraction, the ore is first crushed and treated with the CN solution, which then becomes a flowing slurry during the gold extraction process. 

After gold extraction, the residual slurry ore wastewater solution is then transferred and stored for treatment by a mine operator to dissipate the high levels of CN. Due to its toxicity, the wastewater must be treated and evaluated to ensure that the CN level has been reduced to a safe level before discharge as effluent into the water system to prevent water supply contamination that could endanger people or wildlife. The human exposure limits for CN vary by the type and form of CN compound. According to the United States National Institute of Occupational, Safety & Health (NIOSH), the recommended exposure limit (REL) for NaCN is 5mg/m3 (4.7 ppm) over 10 minutes. Toxic exposure symptoms can include eye or skin irritation, asphyxia, lassitude, headache, vomiting, breathing difficulty and death. 

For these reasons the global mining industry takes CN process safety and environmental stewardship seriously. Industry CN process safety and environmental protocols are rigidly adhered to by mine management and employees. These protocols include required equipment operation and maintenance procedures. 

The Challenge 

Global mining company OceanaGold’s Haile Mine operation, which is located in the U.S. state of South Carolina, contacted the applications team at Electro-Chemical Devices (ECD) in Anaheim, California, to discuss its CN wastewater treatment process. The CN analyzers supporting the mine’s wastewater treatment process were requiring unusually high levels of maintenance, which also left open the possibility of inaccurate measurement, which is unacceptable. Gold was discovered in 1827 by Benjamin Haile in South Carolina and his Haile Mine has been in production on and off for nearly 200 years. In fact in the late 19th century, the Haile Mine was the most productive and profitable gold mine east of the Mississippi River. Today, the OceanaGold employees at the Haile Mine are proud of their company history and are deeply committed to safety and the protection of the environment. 

According to the U.S. Environmental Protection Agency (EPA), the best available technologies for CN wastewater remediation treatment are: oxidation by chlorine, ion exchange and reverse osmosis. The EPA has established a maximum contaminant level (MCL) of 0.2 mg/L and a maximum contaminant level goal (MCLG) of 0.2 mg/L as free cyanide prior to plant discharge of wastewater. In addition, CN wastewater streams are mobile in soils and have low adsorption to soils with high pH, high carbonate and low clay content. Untreated or ineffectively treated CN wastewater streams can leach to groundwater. Under typical conditions in natural waters (pH less than 9.2), most free cyanide is expected to convert to hydrogen cyanide that is highly volatile. The operations team at the Haile Mine relies on a three-step oxidation process to treat its CN wastewater. CN analyzers are placed at the starting point of the treatment process to measure CN levels entering the primary process, at the secondary treatment process to measure treatment effectiveness, and they are placed at the end-point of the process to ensure treatment has been completed to required effluent levels and meets regulatory requirements prior to discharge. 

Should the analyzer report CN levels above the legal limit, the water is returned to the system for additional treatment. Failure to meet the U.S. OSHA and U.S. EPA regulations for the safe use and treatment of CN can result in complex investigations, required actions and fines. 

The Solution 

The Haile Mine operations team was looking for a highly reliable and accurate CN analyzer solution, which also required a less frequent maintenance schedule. After reviewing the mine team’s operational requirements, the applications engineers at ECD recommended the company’s S80-T80 CN Analyzer System for a number of reasons. 

The company’s CN Analyzer Monitoring System is designed with an advanced, precision Pion CN sensor and a smart dual-channel universal transmitter. The Haile Mine plant operations team felt confident that the combination of the highly accurate Pion CN sensor with an intelligent dual-channel transmitter would help them achieve a more cost-effective CN treatment system with reduced maintenance at a lower analyzer lifecycle costs. 

The Pion CN electrode is a combination electrode with a silver cyanide/silver sulfide (AgCN/AgS) solid-state pressed crystal sensing element and a double junction reference electrode. The CN ion selective electrode cartridge develops a millivolt potential proportional to the concentration of free CN ions in the measured solution. The typical output is 54mV to 60mV per decade of change in concentration. The speed of the Pion CN sensor’s response varies from a few seconds in concentrated solutions up to a few minutes in the lower ppm ranges. The CN Pion sensors are used with the dual-channel transmitter, which allows mix and match capabilities that could include the measurement of pH, ORP or other parameters for example. This analyzer measures CN from 0.2 ppm to 260 ppm and auto-ranges the display between the ppb and ppm scales. 

The CN Pion sensors can be inserted into either immersion or insertion type packages that are designed with a 0.75-inch MNPT compression fitting as the process connection. The Haile Mine plant operations team appreciated the flexibility of this design, which also employs a variable insertion length to accommodate installation in pipe tees, flow cells or through tank walls. The sensor’s retractable configuration is designed with a 1-inch MNPT ball valve, a 1-x-0.75 inch reducer and a 0.75 inch MNPT compression fitting to provide the process connection. 

The smart universal transmitter is designed for the continuous measurement of multiple parameters in a general-purpose industrial environment. It communicates with multiple pre- calibrated sensors that measure various parameters and automatically configures the transmitter’s menus and display screens to the measured parameter. With the transmitter’s auto configuration capability to any of the available sensor measurements, the mine operations team no longer needed to maintain an inventory multiple instrument types, saving time and reducing plant operating costs. Technicians at the mine required no special training with the transmitter’s membrane switch navigation. A simple menu structure with soft key menu choices and an easy-to-read 2.75- x-1.5-inch LCD display made the set-up easy. The mine team also like the flexibility of transmitters 4-20 mA output with MODBUS RTU on 24 VDC and 110/220 VAC instruments. The transmitter also can be configured with HART® 7 communications and a three-alarm relay. 

Conclusions 

The new CN analyzers were installed and operational in less than 30-minutes each with no special technician training or tools. They have been operational now for over __ (years or months) with no issues reported. The mine operations team has recommended the CN analyzer system for use at additional company mines worldwide.
