Effect of upflow liquid velocity on size and activity of granular sludge in Expended Granular Sludge Bed(EGSB) reactor

EGSB 반응조 운전시 상향유속이 입상슬러지의 크기 및 활성도에 미치는 영향

The effect of upflow velocity on size distribution and activity of granular sludge was studied in laboratory-scale Expended Granular Sludge Bed(EGSB) reactor fed with non-fat dry milk and sucrose as sole carbon and energy source. High upflow velocity advanced size and activity of granular sludge by distribution and floatation of granular sludge. Therefore, the reactor operation of an apt upflow velocity was needed and an apt upflow velocity in this experimental was estimated to 1-10m/hr.
