A » A trickling filter is a biological treatment process used in wastewater purification. It involves a bed of porous media, such as rocks or plastic, over which wastewater is distributed. Microorganisms grow on the media surface, forming a biofilm that degrades organic matter as the water trickles through. This aerobic process reduces biochemical oxygen demand (BOD) and suspended solids, resulting in cleaner effluent suitable for further treatment or discharge.

A »A trickling filter works by allowing wastewater to trickle over a bed of media, such as rocks or plastic, where microorganisms grow and break down organic matter. As wastewater flows through, microorganisms degrade pollutants, purifying the water. The treated water is then collected and further processed or discharged.
