Precipitation formation is a promising approach to recover phosphorus by extracting phosphate and ammonium ions in wastewaters; however, the operating costs need to be considered when the nitrogen and phosphorus loading increase. In this study, a modified process is suggested, using an aerobic granule forward osmosis membrane bioreactor (AG-FOMBR) to estimate the recovery efficiency. In this bioreactor, organic matters were digested by the biological process while phosphate ions were rejected by the Thin-film Composite (TFC) FO membrane and accumulated. Aerobic granules, as a compact form of microbial aggregates with good settleability and capability to treat high-strength wastewaters, were seeded to compare the membrane water fluxes with the sludge form. The AG-FOMBR showed 95.8%, 37.4%, and 100% overall removal of PO43--P, NH4+-N, and TOC in the first stage, and 95.5%, 46.0%, and 100% in the second stage, respectively. The solutes leakage of TFC membrane is measured and discussed. Recovery benefits through AG-FOMBR, OMBR, and FO (directly removing phosphorus from synthetic wastewater by FO) are evaluated. The global phosphorus recovery efficiency in this suggested reactor was 97.0% in average during the 75-day operation. Duu-Jong Lee 李篤中 2015 學位論文 ; thesis 62 en_US |
