Wastewater Treatment Industry

Wastewater treatment plants are an integral part of every community. Their design needs to perform in a demanding, corrosive, noxious, and highly regulated environment. By their nature, they create a corrosive environment and replete with corrosive gases which degrade metal surfaces and the functionality of ventilation equipment.  We can supply equipment to address these environments using construction options of SS, FRP, and PVC.  Where anaerobic digesters are in place and methane gas is recycled for energy recovery, explosion protection is available for the inlet and exhaust systems of gas engines to protect from overpressure events which can occur regularly in these systems.

Ambient environments having hydrogen sulfide gas and moisture, produce sulfuric acid that degrades painted carbon steel and aluminum air handlers and exhaust fans. Methane, a potential hazard, is a second gas that may need to be addressed.  Stainless steel, fiberglass axial and centrifugal fans are mandatory for those areas of a facility such as the sludge drying area, pumping stations, and wet wells.

Air supply and exhaust openings to the plant can be directed through FRP duct, fittings, louvers, and dampers.  Final selection of equipment construction is predicated on the level of gases in the surrounding environment.  These plants cannot go “down” and need to be operating at the peak of their capacity, so minimal maintenance and longevity of equipment are critical as well as spares parts and redundant systems.   Noise can be an issue depending upon the location of the mechanical equipment and the proximity to housing.  Exhaust fans can be quieted, and interiors can be attenuated for operator safety.
