Wastewater treatment and gas detection
Wastewater treatment is an essential process to ensure the availability of clean and safe water resources for both civil and industrial use. However, potentially hazardous gases can be produced or released during these processes, making it essential to adopt reliable gas detection systems to protect both operators and the surrounding environment.
Wastewater treatment: the benefits of gas detection
The various stages of wastewater treatment can generate gases such as methane (CH4), hydrogen sulphide (H2S), carbon dioxide (CO2) and oxygen (O2), which can pose significant risks:
- Health hazards: toxic gases such as H2S can be lethal even at low concentrations.
- Fire or explosion hazards: flammable gases such as methane can accumulate and cause explosions.
- Environmental impact: uncontrolled emissions can contribute to air pollution.
Gas detection technologies in wastewater treatment
Gas detection systems used in water treatment are based on different technologies, each with specific characteristics:
- Electrochemical sensors: ideal for detecting toxic gases such as H2S, they are accurate and specific but require regular maintenance.
- Infrared (IR) sensors: used to detect flammable gases such as methane, they offer high stability and long life.
- Catalytic sensors: particularly suitable for detecting flammable gases, they are inexpensive but can be affected by contaminants.
Wastewater treatment: the most common applications
Gas detection is essential in several areas of water treatment plants:
- Anaerobic digestion tanks: methane is produced here during the decomposition of organic matter.
- Pumping stations: the accumulation of gases such as H2S is common due to the decomposition of sulphides.
- Storage tanks: may contain dangerous gases released during treatment.
- Closed or underground areas: require continuous monitoring to prevent gas accumulation.
