The upflow anaerobic sludge blanket process was developed by lettinga in the netherland during the early 1980s, as a relatively simple wastewater treatment system, in which no moving parts are present The increased contact time with the active biomass (sludge) results in improved treatment. Its design ensures increased contact time of the wastewater with the sludge and hence increases the efficiency.

An anaerobic baffled reactor (abr) is an improved septic tank (s.9) with a series of baffles under which the wastewater is forced to flow. At first, the reactor were fed with 100 mg/l of cod and increased gradually until 1000mg/l of cod to ease The design consists of a series of staggered vertical baffles which the wastewater passes over and. The baffled design of the abr ensures high solids retention resulting in high treatment rates, while the overall sludge production is.
