SEWAGE TREATMENT – TECHNOLOGIES

Upflow Anaerobic Sludge Blanket Reactor (UASB) • The Up flow Anaerobic Sludge Blanket reactor (UASB) maintains a high concentration of biomass through formation of highly settleable microbial aggregates. The sewage flows upwards through a layer of sludge. • The sludge in the UASB is tested for pH, volatile fatty acids (VFA), alkalinity, COD ...

Comparisons Between the UASB and the EGSB Reactor Seung …

The Upflow Anaerobic Sludge Blanket (UASB) reactor was developed by Lettinga and his colleagues in Netherlands (Wageningen University) in late 1970s. The granule was reported by Young and McCarty (1969) in their anaerobic filter system first and was observed in South Africa during Lettinga’s trip before developing the first UASB reactor.
