Trickling Filters - Sewage Treatment - Reverse

Sewage trickling filters are used in areas not serviced by municipal wastewater treatment plants (WWTP). They are typically installed in areas where the traditional septic tank system are failing, cannot be installed due to site limitations, or where improved levels of treatment are required for environmental benefits such as preventing contamination of ground water or surface water.

Trickling Filter - an overview | ScienceDirect Topics

In modern wastewater treatment plants, the trickling filter is composed of plastic units (Figs. 22.9 and 22.10). In older plants, or developing countries, the filter is simply a bed of stones or corrugated plastic sheets through which wastewater drips (see Fig. 22.7). This is one of the earliest systems introduced for biological waste treatment. The effluent is pumped through an overhead

What every operator should know about trickling filters

Trickling filters became the dominant secondary treatment process in the U.S. by the 1950s. Trickling filters fell out of favor in the 1970s when the U.S. Environmental Protection Agency issued its definition of secondary treatment standards — activated sludge was better able to meet the new standards. Improvements in secondary clarifier design and the introduction of coupled processes
