It was found that longer accli mation of sludge in the plants gave higher production of methane. In addition > 1: 1 water diluted slop enhanced COD reduction and reduced the range of pH variation. Addition of nutrients like nitrogen and phosphorus did not significantly affect t h e anaerobic process in 2 phase UASB. High concentration ( 1 2. 5 g/l) of potassium did not affect the methane production> as well.
