Treatment of methanolic wastewater was studied in an anaerobic sequencing batch reactor (ASBR) for a period of 193 days. The results showed that the system worked efficiently when the system volume loading was of 4–8g COD/l. d. Both Methanol concentration and bicarbonate play an important role in the anaerobic conversion of methanol.
