Protection of Waste Water Treatment Plants
Wastewater treatment plants generate biogas during anaerobic digestion and related processes. This gas is routed through storage vessels, treatment units, gas lines, and utilization systems such as CHP units or flares. Each section of the system presents distinct operating conditions, including fluctuating pressures,

Vacuum is the pressure in an enclosed space that is lower than the ambient pressure.

Protection concepts shown include pressure and vacuum relief devices installed on digesters and storage tanks, as well as in-line Flame Arresters positioned along gas conveyance piping. End-of-line and in-line

Equipment
Machines, appliances, fixed or mobile devices, control parts and accessories, and warning and prevention systems, whether separate or combined, intended for the generation, transfer, storage, measurement, control, and conversion of energy, and for the processing of materials, which have their own potential source of ignition and may cause an explosion.
and prevent flame transmission into critical process units. Components are arranged to support correct tank breathing, emissions control, and safe isolation of ignition sources.
Protection of Landfill Plants
Landfill gas collection systems transport combustible gas mixtures from extraction points to utilization or flaring units. These systems typically operate under varying flow rates and pressures and require robust protection against

Flashback
Phenomenon occurring in a flammable mixture of air and gas when the local velocity of the combustible mixture becomes less than the flame velocity, causing the flame to travel back to the point of mixture.

The illustrated protection layout includes in-line Deflagration Flame Arresters installed in gas lines, as well as Flame Arresters at terminal points such as flares. Equipment placement supports safe gas transport from the landfill body to enclosed machinery units and downstream systems, while reducing the risk of flame propagation back into the collection network.
Highlights
Verified flashback protection
Fewer fouling issues
Safer burner/flare tie-ins
Optimal product selection
