Landfill and Wastewater Treatment Plants

Protection of Landfill and Biogas Systems​

Our advanced safety solutions – including  Flame Arresters and Pressure/Vacuum Relief Valves – ensure efficient waste management and reliable environmental protection.​
Tailor-made safety concepts are designed to meet each customer’s specific requirements while complying with local standards and regulations, ensuring safe and fully compliant operations which are simple to maintain during the life of the asset.

Protection of Waste Water Treatment Plants

Wastewater treatment plants generate biogas during anaerobic digestion, which is routed to storage tanks, treatment units, gas pipelines, and utilization systems such as CHP units or flares. Each section is exposed to specific conditions, including pressure fluctuations, vacuum Dépression Vacuum is the pressure in an enclosed space that is lower than the ambient pressure. situations, and the risk of flame propagation.​

Pressure / Vacuum relief valves and Flame Arresters are installed on digesters, storage tanks, gas boosters, and flares. These  Flame Arresters protect downstream equipment and prevent flame transmission, ensuring proper tank venting, effective emission control, and safe isolation of potential ignition sources.

Protection of 
Landfill Plants

Landfill gas collection systems transport combustible gas from extraction points to utilization or flaring units, operating under varying flow rates and pressures and requiring protection against flashback, deflagration, and endurance burning Endurance burning Stabilized burning for an unlimited time. . ​

Protection includes in-line Deflagration and Detonation Flame Arresters in gas lines and at flares. Equipment placement ensures safe gas transport and reduces the risk of flame propagation back into the collection network.
