Applications

Our patented* 4" Biotube® Effluent Filters, Biotube Jr., Biotube® Insert Filters, and Biotube Base Inlet Filters are ideal for residential septic tanks. They prevent large solids from leaving the tank, dramatically improving wastewater quality and extending the life of residential drain fields.

Effluent filters resist clogging better than all other brands. Our standard, full-sized 4" Biotube® Effluent Filter provides maximum long-term protection in a complete package, with housing. Our 4" Biotube® Jr., at half the size of our standard model, has more filtering capacity than the full-sized filters sold by other manufacturers. For tanks with existing outlet tees, the Jr. Insert Filter is ideal. And for low-profile tanks, there's the Base Inlet Filter.

Biotube® Filtering Process

Effluent from the relatively clear zone of the septic tank, between the scum and sludge layers, horizontally enters the Biotube® Effluent Filter. Effluent then enters the annular space between the housing and the Biotube®, utilizing the Biotube®’s entire surface for filtering. Particles larger than the Biotube®’s mesh are prevented from leaving the tank.
