*[[Anaerobic_Baffled_Reactor_(ABR) 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.
