Wastewater Treatment Effluent Filter | Polylok PL-525 Effluent Filter | 1/16" Wastewater Filtration

The PL-525 Filter is rated for 10,000 GPD (gallons per day) making it one of the largest filters in its class. It has 525 linear feet of 1/16” filtration slots. Like the Polylok PL-122, the Polylok PL-525 has an automatic shut-off ball installed with every filter. When the filter is removed for cleaning, the ball will float up and temporarily shut off the system so the effluent won’t leave the tank.
