It has been said that the UASB procedure is a crucial part of cutting-edge technology for environmental protection, among other treatment methods. This review explains the UASB's influencing variables, operating conditions, and fundamental design concepts. To achieve the best outcomes, temperature, granulation, OLR, HRT, mixing, and their effects on the operation of the UASB reactor and hydrogen generation were all proven. Additionally included are post-treatment techniques that successfully release and/or reuse treated water. The review put for t determine the optimal method for creating the UASB reactor.
