Abstract

Moving bed biofilm reactor (MBBR) systems have been proven as an effective technology for water treatment and have been used for BOD/COD-removal, as well as for nitrification and denitrification in municipal and industrial wastewater treatment. Conventional Activated Sludge, in particular, has been extensively used in wastewater treatment since decades ago. In this study, physical performance results for both MBBR and Conventional Activated Sludge (CAS) were compared and evaluated on laboratory scale basis. The study aims to identify the best system performance in terms of constituent removal efficiency for effective management of the river purification plant. A novel parallel MBBR and CAS pilot plant were fabricated and operated to compare the physical performance of MBBR and CAS. From the result, MBBR has higher COD (58%), AN (75%) and TSS (80%) removal rate compared to CAS COD (53%), AN (53%) and TSS (69%).For BOD removal rate, CAS shows 68% removal rate whereas MBBR shows only 65%. Thus CAS has shown slightly higher removal rate than MBBR. In terms of sludge production, MBBR sludge is less than CAS. Overall performance proves that MBBR has better rate of constituent removal efficiency compared to CAS in the laboratory basis study.
