SaniTEE effluent screening devices from Bio-Microbics protect absorption areas from premature clogging and failure due to the release of nonsettleable solids and/or nondegradable flushed materials from the septic tank. Available in 4-, 8- and 16-inch-diameter sizes, the unit installs directly in the outlet tee of the tank. Its keyhole weirs provide consistency of flow despite surges. The angled slots resist blinding and prevent clogs inside the filter housing to extend the life of the system, reduce clogging material, and improve flow conditions. It has easy slip-in installation and comes standard with a swabbing feature for clean-in-place maintenance. 800-753-3278; www.biomicrobics.com.
