Upflow Filters for Septic Tank Effluents

Abstract

Upflow filters are a simple and inexpensive method for treating septic tank effluents in rural and suburban communities. Such filters can achieve biochemical oxygen demand removal efficiencies of up to 75 percent and can operate at hydraulic loading rates slightly greater than those for low-rate trickling filters. Maintenance is simple, head losses are low, and the filters can operate continuously and unattended for long periods.
