Abstract
A septic tank effluent filter includes a housing positioned external to and downstream a septic tank for receiving the effluent prior to it being released into a drainfield positioned downstream the housing. The housing includes an inlet port and an offset outlet ports on an opposing wall for connection between the septic tank and drainfield. A cylindrical container is carried within the housing and is connected directly to the outlet port for having the effluent flow from within the housing through the uniformly perforated cylindrical wall of the container to outlet port. A circular base plate of the container provides a baffle and prevents the undesirable direct streaming of the effluent from the inlet port to the outlet port. A plastic mesh bag is filled with polystyrene plastic beads having a large surface to volume ratio, thus a large surface area within a desirable space. The bead filled mesh bag is carried within the container such that the effluent entering the housing from the septic tank flows through the bead filled bag, permitting organic matter including bacteria to be collected on bead surfaces prior to the effluent flowing out of the housing and into the drainfield.
