Anaerobic degradation of the pharmaceutical industry wastewater is carried out in the hybrid UASB reactor. Based on the results, I can conclude that the UASB reactor and the modification done in the reactor can be used for the pharmaceutical industry wastewater. The maximum COD removal efficiency is 71.99 % with average effluent COD concentration as 62000 mg/l. In 1st recycle it is 56.75% max and 66.27% max it is increased to 69.35% in 1st continuous...
