Abstract
Waste water from wheat starch production was treated by a membrane com bined two phase methane fermentation system with 20kg/m(3)d of COD loa ding. The following satisfactory results were obtained: BOD and SS con centration in the system effluent was under 50 mg/l and 90 mg/l respec tively, More than 99% of organic matter was removed. About 40,000 kcal of methane gas energy was recovered in an operation of 12-22kg/m(3)d, and the average methane gasification rate and sludge yield rate were 0.33Nm(3) CH4/kg COD removed, and 0.12kg VSS/kg COD removed respective ly.
