Proven wastewater treatment technology for residential, commercial and small community needs

Zoeller Pump’s Recirculating Media Filter (RMF) is designed for use in decentralized wastewater treatment applications where the effluent quality must meet or exceed secondary treatment standards. The RMF technology can be used in residential, commercial, or small community applications for treating residential strength wastewater from a septic tank. Treatment occurs below grade as the fluid trickles down through the pore spaces of the media where aerobic organisms feed on the nutrients. Effluent leaves the system through an outlet pipe in the bottom of the filter. Treatment capacities range from 450 gpd to more than 36,000 gpd. Multiple RMFs can be used together when greater capacities are needed. Effluent can be discharged above or below grade. Above grade disposal must meet local health codes or guidelines.
