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 way 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 clogging of pumps and check valvesSewage Wet Wells Need Aeration and Mixing

The Pro-Air wet well aeration system is very cost-effective, often costing less than 80% of the cost of chemical feed systems, plus lower operating costs.

Pro-Air systems include a regenerative blower, intake filter, pressure relief valve, control panel, and piping in the wet well. The control panel includes a cycle timer to adjust blower operating time and is interlocked to the pump starters to turn the blower off when a pump is operating.  The blower can be base mounted, wall-mounted, or provided with a fiberglass enclosure for outdoor installation. 

Blowers can be provided for single-phase, 120/240 volt, or three-phase, 208/240/480-volt electrical service. Motor sizes vary from 1/2 HP to 5 HP depending on the size of the wet well and the water depth. Contact Envirep for sizing recommendations.
