SaniTEE® wastewater screens are now available in 4", 8" and 16" sizes and provide consistent retention of wastewater solids for applications up to 20,000 gallons per day. Multiple SaniTEE screens can be used for flows above 20,000. SaniTEE® Wastewater Screens SaniTEE® self-cleaning wastewater deflection screens (commonly known as septic tank effluent filters) are designed to reduce suspended solids discharged in septic tank effluent by promoting natural sedimentation and excluding gas-lifted particles from entering the outlet pipe. Additionally, SaniTEE’s patented keyhole weirs help to attenuate surge flows, delivering a more consistent flow for further treatment or dispersal. These features help extend the lives of drain fields, reduce the clogging of orifices in effluent disposal systems and allow flexibility in the use of different types of effluent pumps.
