Orenco's Biotube^® effluent filters prevent the discharge of large solids from the tank, dramatically improving the quality of effluent and extending drainfield life.

Effluent from the relatively clear zone of the septic tank, between the scum and sludge layers, enters the Biotube effluent filter through its vertical inlet holes. Larger particles are retained in the interior space, where further decomposition of organic materials occurs. Optional flow modulating orifices at the outlet of the filter slow the flow through the tank, allowing maximum settling of solids.

Effluent filters are not all alike. Ours have 5-10 times more flow area than others, so they don’t need to be cleaned as often, and that reduces maintenance time and cost.
