Gas and associated risks in water treatment

Wastewater and potable water treatment facilities produce and use various toxic and explosive gases such as methane, hydrogen sulphide, ammonia, carbon dioxide, carbon monoxide, chlorine and ozone. In addition, in confined spaces, the increased formation of toxic gases and decreased concentration of oxygen make these areas particularly dangerous for workers.

The risk can be evaluated by measuring worker exposure to various pollutants present in the air in work areas. The measured concentrations are then compared to the eight-hour time-weighted averages for exposure (TWA) and recommended exposure limits for shorter time periods (less than 15 minutes).

Gas and flame detection products and solutions in water treatment

Several technologies can be employed to detect gases present in water treatment facilities.

• Electrochemical sensors are used to monitor oxygen rates in the air, or the presence of toxic gases such as CO, H2S and Cl2
• Semi-conductor sensors are used where there are high concentrations of H2S or where the ambient temperature is high
• Catalytic sensors are used for the detection of explosive gases
• Infrared sensors detect explosive gases such as CH4 or carbon dioxide (CO2)
• Infrared technology sensors are recommended for corrosive atmospheres or where high levels of H2S are present. Continued high concentration of H2S (above 3ppm) will create a risk of saturation and poisoning for standard catalytic cells.

Teledyne Gas & Flame Detection’s infrared sensor cells are not sensitive to poisons such as H2S and chlorinated solvents, as well as lasting longer than other models. Maintenance is reduced to one annual test. Energy consumption is half than that of catalytic detectors, and they are guaranteed for five years.

A wide range of fixed and portable detectors in water treatment

With more than a century of experience, Teledyne Gas & Flame Detection has been innovating and building expertise in gas detection in order to improve safety in the workplace. The industrial product line was designed to be used in the most extreme environments and is well-adapted for use in the water sector. Use is possible in areas with and without explosion hazard classifications, high protection index, stainless steel or polyester casing.

Our units have many functional features, including RS485 outputs, TCP/IP interfaces, programmable relays, backlit LCD displays and 24/7 data recording.

Biological treatment facilities are usually situated far from production facilities, and staff who work at and maintain these facilities often work alone. For complete safety, operators are equipped with portable gas detectors, which are maintained and tested regularly.
