Gas detection for water & wastewater treatment

Water purification and wastewater treatment processes developed for water sanitation produce many combustible, toxic or asphyxiating gases. This field of activity presents several hazards and potential risks for workers. This is why it is widely regulated with local specific training, mandatory equipment, and safety regulations.

masques gaz et détecteurs gaz pour l'assainissement et le traitement des eaux usées

The most frequently gases encountered in water sanitation and wastewater management are methane (CH4), ammonia (NH3), chlorine (Cl2), ozone (O3), carbon dioxide (CO2) and nitrogen (N2). Each year many severe gas accidents occur worldwide. That’s why it is highly recommended to install and use several water treatment gas detection units.

Water TREATMENT gas detection

4 gas detector

This is the prime multi-gas detector and the most commonly used device for sanitation in wastewater treatment plants. It simultaneously monitors presence of methane (CH4), hydrogen sulfide (H2S), carbon monoxide (CO) and oxygen deficiency (O2). It is also recommended during trainings for water and wastewater treatment workers.

Ammonia detection

Ammonia (NH3) and hydrogen sulfide (H2S) gaseous release at highly toxic concentrations can occur while drying waste sludge (reversal and destocking). For this purpose, wearing NH3 and/or H2S gas detection devices is essential for worker’s health and safety.

Chlorine and ozone detection

Amongst every water purification processes, the tertiary treatment consist of eliminating residual phosphor, chemical or biological micro-pollutant from the treated water. Purification techniques can be either physical (sifting, micro filtering) or chemical, usually through chlorine (Cl2) or ozone (O3).

Water and wastewater treatment respiratory protection

Emergency escape breathing device – EEBD –

An escape respirator is a respiratory protective device dedicated to outdoor emergency evacuation. This is either a half-mask or a hood equipped with an ABEK specific filter. They are designed for protection against organic, inorganic (except carbon monoxide), acid substances, ammonia and sulfur compounds with a 15 minutes autonomy – time to evacuate.

Self-rescuer mask -SCSR

self-rescuer mask is a respiratory protective equipment especially designed for emergency evacuation in non-breathable atmospheres. As it is the safest emergency escape device, it is recommended during confined space trainings for any wastewater treatment worker.

CONFINED SPACE TRAINING

Any wastewater treatment worker who potentially enters a confined space need to receive some confined space training, depending on the level of work.

With local training (like CATEC® training in France, confined space certifications in the UK, or OSHA confined space training in the USA), learners understand more about safe work practices, suitable control measurements and what the regulations sates in regards to safety at work. Once trained, water treatment workers are aware of confined spaces dangers and understand the importance of implementing appropriate control measures and necessary emergency procedures.

VENTIS-MX4 portable gas detector that complies with ATEX standards. This detector can detect from 1 to 4 gases with a large range of sensor combinations (Explo 0-100% LEL, O2, CO, H2S, NO2, SO2).

Portable 4 gas detector – VENTIS-MX4 – EXLO, O2, CO, H2S

VENTIS-MX4 portable gas detector that complies with ATEX standards. This detector can detect from 1 to 4 gases with a large range of sensor combinations (Explo 0-100% LEL, O2, CO, H2S, NO2, SO2).

Portable gas detector MX4-Ventis
  • Detection of Explo (0-100% LEL), O2, CO, H2S, NO2, SO2
  • Robust, shock-resistant and waterproof device (IP66 and IP67)
  • Enhanced visibility with safety orange overmold
  • Compact and lightweight: first multigas detector with a single-gas detector size
  • Optional slide-on sampling pump (up to 30 meters)
Additional information

The Ventis-MX4 is a portable multigas detector. Contrary to single-gas detectors, it can detect up to 4 gases. Thanks to its rechargeable Li-ion battery, it can continuously operate during around 12 hours at 20°C ambient temperature. This battery can be replaced by an optional extended battery for up to 20 hours of autonomy without pump.

The Ventis-MX4 portable gas detector can detect up to 4 gases amongst explosive gases, oxygen (O2), carbon monoxide (CO), hydrogen sulfide (H2S), sulfur dioxide (SO2) and nitrogen dioxide (NO2). A specific location is dedicated to the explo sensor (catalytic sensor) and the oxygen sensor (electrochemical sensor). A 4 gas unit will basically include oxygen and explo sensors.

The Ventis-MX4 features 3 different alarms. The first one is a powerful 95 dB at 30 cm audible alarm to alert in noisy environmets. A high visibility red LED visual alarm and an ultra- vibrating alarm are added to improve safety. Two alarm levels are configures: low and high alarms – which are basically calibrated under occupational safety at work data.

The Ventis-MX4 portable gas detector also features the same physical properties – dimension and weight – than a single-gas detector. It can be wore close to the breathing tracts thanks to its crocodile clip without disturbing the user. This multigas detector shock-resistant and waterproof thanks to its high visibility polycarbonate-made overmold.

As this device can detect explosive gases, it meets current EU ATEX standards (explosive atmosphere). A sampling pump – VSP for Ventis-MX4 – is available to draw remote samples (up to 30 meters) before interventions – e.g. in confined space.
