Brewery wastewater was collected from Breweries Ltd., located
in Gangneung city in Korea. The company produces large amounts
(approximately 1500 m3
/day) of wastewater. Wastewater in an aerobic
tank was used for the experiment. Water quality characteristics of the
brewery wastewater are summarized in Table 1. The ratio of biochemical
oxygen demand (BOD) and COD ranged from 0.3 to 0.5 in the influent
and aerobic tanks. The average pH was relatively low and was measured
at 5.1 for the influent tank and 6.5 for the aerobic tank
