Pro-Air - Wet Well Aeration Systems

Envirep’s Pro-Air wet well aeration systems offer an effective, low-cost, energy-efficient solution for pump station grease removal and odor control. Sewage wet wells are designed to provide adequate storage volume of wastewater to prevent the short cycling of pumps and motors. Storage of raw wastewater in a wet well poses several problems, such as odors, grease buildup, corrosion, and accumulation of rags and debris. Wet well aeration and mixing is an effective ways to eliminate these issues.

The wet well aeration provides enough oxygen to saturate the wastewater and produce extreme agitation of the wastewater to break up the grease layer and mix the grease into the wastewater. The high level of agitation also re-suspends heavy solids to keep the wet well bottom from accumulating solids and prevent the pump inlet pipes from bridging and clogging.

The Pro-Air aeration and mixing system is integrated with the pump controls to operate when the pumps are off to prevent air entrainment through the pumps. The controls also include a cycle timer to reduce operating time and maximize the efficiency of the system.

Pro-Air wet well aeration systems provide the following benefits:

Breaks up troublesome grease
Keeps dissolved oxygen levels high, which reduces the production of toxic gases and odors
Reduces corrosion in sewage lift stations and force mains
Helps prevent the clogging of pumps and check valves
