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.

Gas monitors ane PPE for wastewater and water treatment works

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.

  • Dimensions: 104 x 58 x 36 mm – weight: 200 grams without pump
  • Audible (95 dB), LED visual (2 red and 2 blue) and vibrating alarms
  • Rechargeable lithium-ion battery with optional extended battery
  • Polycarbonate housing with waterproof rubber overmold (IP68)
  • Datalogging over 3 months with 10 seconds interval
Additional information

The Ventis Pro5 multi gas detector was especially designed to silmutaneously detect up to 5 gases among the combustible gases, NH3, CO, CO/H2S, H2S HCN, NO2, O2, SO2, CO2 and HC.

 

This flexible detector features a panic button to alert nearby teams when user is in distress. It also features a mandown alert function which is set to activate after a defined period of time without motion.

 

In case of anormal concentrations, powerful audible (95 dB à 10 cm) and visual (ultra-bright blue and red lights) alarms will alert any operator working in the area, even in high-noise and dark environments.

Custom alarm action messages like “EVACUATE” or “VENTILATE” can furthermore be configured in case of emergency situations in order to safely and quickly take corrective actions.

 

Made of polycarbonate with protective rubber overmold, this gas detector is available either in black or high-visibility safety orange versions and can be combined with the VSP slide-on pump. Its integrated data logger can record up to 3 months of events. Water and dust-resistant (IP68), the Ventis Pro5 can be used in pumped version for use in confined spaces or without pump as a personal protective equipment.

 

The Ventis Pro5 portable multi gas detector also features the LENS Wireless technology. LENS is the first wireless gas detection solution that allows personal monitors and area monitors to communicate gas readings and alarms with one another. This way, panic and mandown alarms will be communicated to other Ventos Pro detectors operating in the same area in order to alert everyone on the hazardous situations.

 

Lastly, the Ventis Pro5 benefits from the iAssign® technology for site and user follow-up. Thanks to this enhanced technology, every data recorded by the device will be assigned to the user ID. This process allows amongst other things users to wear several gas detectors within the same working day.

Additional information

Especially designed for use in hazardous atmospheres, the X-am 2500 portable multi gas detector is ATEX approved for zone 0 (permanent explosive atmosphere). This small 4 gas monitor can accurately and reliably detect the presence of up to 4 gases among O2 (oxygen), CO (carbon monoxide), H2S (hydrogen sulfide), NO2 (nitrogen dioxide) and SO2 (sulfur dioxide).

The powerful tiny sensors of the X-am 2500 multi gas detector allow safe and reliable detection of hazardous gases concentrations. Thus these high performance gas detection sensors are ideally well-suited for industrial applications and refineries. Moreover, thanks to their unique design, these gas detection sensors feature a long-lasting shelf life – up to 5 years for O2, CO and H2S sensors. This high sensor durability then enables reduction of gas detection related operating costs.

Thanks to its compact and lightweight design associated to a robust crocodile clip, the X-am 2500 portable 4 gas monitor can be easily and comfortably worn on a belt or on a collar without disturbing the user. Moreover, this portable multi gas  detector features several gas entries on the top and on the front in order to properly operate even if the device is inside a pocket or if one of the entries is accidentally covered. As a safety device against potentially dangerous gas concentrations, the X-am 2500 has a 3 years guarentee to ensure maximum security to its user.

The X-am 2500 portable gas monitor  features a large easy to read LCD display. All of the target gases are simultaneously displayed on the screen and once a gas alarm occurs, the hazardous target gas is highlighted for fast recognition of the hazard. The ultra-bright visual alarm can be seen at 360° and is coupled with acoustic 90 dB at 30 cm and vibrating alarms.

An optional gas sampling pump is available to draw remote samples up to 30 meters in order to get sure of gases concentrations in confined spaces like tanks or pits before any intervention. This gas sampling pump, designed for this 4 gas monitor, automatically triggers upon the device start-up and it is very easy for the user to switch from pump mode to diffusion mode without any tool.
