Water and Wastewater Treatment Plant Gas Detection
The water industry
In the water and wastewater industry toxic and flammable gases pose a significant safety threat as does the risk of oxygen depletion.
Our Solution To Ensure Safety For Water And Wastewater Treatment Plants
We have the skills and expertise to design, install, and maintain a cost effective gas detection system to ensure complete safety for all water and wastewater plants.
Clean water production
Clean water needs to be filtered to remove particles before it is disinfected with either ozone or chlorine to kill any bacteria in the water. Once disinfected the water is then dosed with sodium bisulphate to reduce the PH levels before finally being filtered through carbon beds to remove any odours and tastes. The biggest dangers presented here are from oxygen depletion and the potential exposure to chlorine, ammonia, and ozone.
Gas detection systems are installed where ozone and chlorine are stored and injected into the dosing process:
- Chlorine and sulphur dioxide drum/bottle stores
- Chlorinator rooms
- Ozone generator rooms
- Daff plants
Waste water Methane
A high number of incredibly toxic and flammable gases are present in the waste water environment meaning that both fixed and portable detectors are required. We have over 19 years’ experience of working specifically in this industry and have developed bespoke solutions along the way to ensure complete safety.
Sewage enters the treatment works and is screened to remove any large objects that may damage or hinder the treatment process. The sewage is then treated in settlement tanks to remove the particulates and bacteria before it is discharged to the watercourse – the resulting sludge from the settlement process is then treated. The sludge contains high levels of sulphates and methane, which can be released during the treatment process.
Gas detection systems for the detection of hydrogen sulphide and methane are installed in buildings where sludge is treated:
- Belt press
- Drum thickeners
- Gravity belts thickeners
- Sludge storage facilities
Biogas is produced by heating sewage sludge and encouraging anaerobic digestion – the natural process where plant and animal materials are broken down by microorganisms in the absence of air. The digestion creates biogas, which is approx. 65% vol. methane. The biogas can be used as a fuel source in combined power and heat (CHP) engines to create electricity and feed the national grid.
The Biogas is extremely explosive and due to the nature of its production contains high concentrations of hydrogen sulphide. Gas detection systems for the detection of hydrogen sulphide and methane are installed in buildings where biogas is stored and used:
- Gas bag storage
- Boiler houses
- CHP enclosures
