The objective of this paper is to critically review the significance of MBR technology for wastewater treatment derived Biodiesel plant with Alkali-Catalyzed Trans-esterification process. The whole study was carried out into two stages. In the first stage, pretreatment was studied with H2SO4 at the different pH range of 2.4 to 9 along with the removal efficiencies of BOD, COD and Oil & Greases....
Sustaining a desired rate of oxygen transfer for microbial activity is a matter of major concern for biological wastewater treatment (MBR). The study reported in the paper was aimed at assessing the effects of microbial products on the specific oxygen uptake rate (SOUR) in a conventional membrane bioreactor (CMBR) and that in a sponge submerged MBR (SSMBR). The production and progressive accumu...
In conventional activated sludge (CAS) involving aerobic biological processes, the retention of silica nanoparticles (SiO2 NPs) has no detrimental effect on chemical oxygen demand (COD) and ammonia nitrogen (NH3–N) removal. However, for the membrane bioreactor (MBR) system, which is also based on the activated sludge process in addition to the membrane separation process, it has implications no...
The performance of a novel industrial membrane bioreactor (MBR) comprising denitrification, nitrification and ultrafiltration for the secondary treatment of primary treated animal rendering wastewater has been compared with an experimental, low-cost and novel vertical-flow constructed treatment wetland planted with Typha latifolia L. The process wastewater followed pre-treatment by dissolved ai...
In this study, a full-scale membrane bioreactor (MBR) was monitored over a period exceeding 6 months. Two common chemical cleaning modes, chemically enhanced backwash and clean in place, with sodium hypochlorite were monitored with respect to microorganism log removal value (LRV). Overall, impact to microorganism LRV for virus, bacteria and protozoa due to cleaning was negligible with respect t...
A hybrid ultrafiltration-osmotic membrane bioreactor (UFO-MBR) was investigated for over 35 days for nutrient and trace organic chemical (TOrC) removal from municipal wastewater. The UFO-MBR system uses both ultrafiltration (UF) and forward osmosis (FO) membranes in parallel to simultaneously extract clean water from an activated sludge reactor for nonpotable (or environmental discharge) and po...
