→‎Primary Treatment

*[[Vermicomposting_digesters|Vermicomposting digesters]]: This system provides aerobic primary treatment by providing an enclosed environment in which worms transform solid effluent into humus. Liquid is separated from solids by draining through a filtration medium that retains solids. Aerobic digestion is faster and generates less smell than septic tanks.

*[[Anaerobic_Baffled_Reactors_Anaerobic_Baffled_Reactor_(ABRsABR)2|Anaerobic Baffled Reactors]]: An anaerobic baffled reactor (ABR) is a tank with several compartments that is designed to reduce the organic and suspended matter in the wastewater by about 70%. Raw wastewater enters the ABR tank through the inlet structure, which directs the flow to the bottom of the first compartment. Due to the nature of wastewater under anaerobic conditions, a granulated sludge blanket is formed. As the wastewater flows up through the sludge granules, the solids are trapped in the sludge blanket where anaerobic bacteria consume the organics as food.
