Wastewater Filtration

Wastewater treatment takes place at the backend of the plant. It usually involves cleaning up the waste streams from multiple sources like the Intake, Process and Cooling areas of a plant. Depending on the location of the plant there may be a variety of regulatory discharge limits that have to be met before

the wastewater can be released from the plant. PEP Filters has a complete line of automatic self-cleaning filtration equipment to help facilities meet their discharge limits.

PEP Filters is a globally recognized water filtration company with a rich history of providing fine filtration solutions for industrial cooling, process water treatment, and commercial HVAC cooling tower applications.
