Trickling filter - Wikipedia
A trickling filter is a type of wastewater treatment system. It consists of a fixed bed of some material, such as rocks , coke , gravel , slag , polyurethane foam , sphagnum peat moss , ceramic , or plastic media, over which sewage or other wastewater flows downward and causes a layer of microbial slime ( biofilm ) to grow, covering the bed of ...

A trickling filter is also called biological filter, as it makes the use of active microbial mass as a bioweapon to degrade the waste out of primary sewage. Unlike activated sludge treatment , the trickling filter follows an attached growth system inspite of suspended growth system.
Trickling filters (TFs) are used to remove organic matter from wastewater. The TF is an aerobic treatment system that utilizes microorganisms attached to a medium to remove organic matter from wastewater. This type of system is common to a number of technologies such as rotating biological contactors and packed bed reactors (bio-towers).

A trickling filter , also called trickling biofilter, biofilter, biological filter and biological trickling filter , is a fixed-bed, biological reactor that operates under (mostly) aerobic conditions. Pre-settled wastewater is continuously ‘trickled’ or sprayed over the filter.
Trickling Filters are a unique type of fixed film biological treatment. In a trickling filter, the micro-organisms used to treat the wastewater are attached, or fixed, to a medium as they contact the wastewater. These micro-organisms form a slime growth on the medium known as zoogleal film.
Stone media trickling filters will be designed with depths of 5 to 7 feet for low-rate and depths of 3 to 6 feet for high-rate applications. Synthetic media manufacturers recommend depths of 10 to 40 feet for columnar or stacked module media.
