Trickling Filters (Rotary Distributors) and Siphon Equipment

A trickling filter, also called trickling bio-filter, bio-filter, biological filter and biological trickling filter, is a fixed-bed, biological reactor that operates under (mostly) aerobic conditions. Pre-settled waste-water is continuously ‘trickled’ or sprayed over the filter. As the water migrates through the pores of the filter, organics are aerobically degraded by the bio-film covering the filter material.
