An easy to install/maintain effluent filter screening device to reduce suspended solids discharged in septic tank by promoting natural sedimentation and excludes gas-lifted particles from entering the outlet pipe. The SaniTEE® self-cleaning wastewater deflection screens (commonly known as septic tank effluent filters) are available in 4″, 8″ and 16″ sizes.
How it Works
As sewage enters the septic tank, grease, oils and light weight particles rise to join the scum layer at the water surface. Heavier solids settle to the bottom to join the sludge layer. In between these layers is a zone of relatively clean effluent. This effluent enters the side of the SaniTEE® screen, passing through the angled slots. Clarified effluent then travels up through the inside of SaniTEE and out through patented keyhole weirs to discharge via the standard outlet piping. As solids come in contact with the smooth vertical surface of the screen, they tend to slough off, falling back into the septic tank, instead of collecting inside the filter housing.
How it Installs
The installation of SaniTEE® consists of dropping it inside a standard septic tank outlet tee. No tools required. When cleaning the SaniTEE, simply move the swab handle up and down to pass the swab through the center screen. This swabbing action willl dislodge any debris that might be trapped in the angled slots. If inspection is required, SaniTEE can be removed easily by simply lifting the screen out of the outlet tee.
Finding the Right Size
It is recommended to check what local regulations are required in case additional information is needed.
