The evaluation of applicability for development of advanced package system (BioKube) for sewage treatment

Nowadays, more developing countries are facing the serious challenge of treating increasing number of decentralized domestic sewage in rural areas. Domestic sewage in rural areas that do not have public sewers must rely on on-site treatment system to manage wastewater. Therefore, new sewage treatment system for domestic sewage is a social concern in rural areas. In this respect, this study aimed to characterize treated domestic sewage by applying high-flux flat membrane to BioKube reactor consisted of aerobic bio-film media with the automatic control function. The BioKube reactor is separated into four chambers and each chamber contains approximately 584, 157, 487 and 118 L of wastewater, respectively. The removal efficiencies of CODCr, BOD5, SS, T-N, NH4+-N and T-P were reached 81.5, 84.8, 81.7, 38.3, 84.6 and 40.1%, respectively at a hydraulic retention time of 22 h. In addition to, T-P decreased from 4.03 to 0.01 mg/L by installation of coagulation-membrane reactor on the latter part and SS concentration decreased by approximately 99.9%.
