Abstract:

Submerged membrane adsorption bioreactor (SMABR) was investigated as a pretreatment to reverse osmosis (RO). SMABR removed organic matter by adsorption and biological degradation. At a powder activated carbon (PAC) residence time of 66d (1.5% of PAC replacement daily), higher organic removal was achieved with removal of a majority of biopolymers (94-97%) and humics (71-76%). A continuous MBR operation with the optimal PAC residence time of 66d was conducted and compared with MBR with no PAC replenishment in terms of the removal of organic and microbes. High removal of organics of up to 72% was maintained with only a marginal increment of trans-membrane pressure and stable bioactivity (total cell number and adenosine tri-phosphate) during the 50d of operation. The SMABR was found to be a sustainable biological pretreatment to RO with only a small amount of PAC requirement (2.14g of PAC/m3of seawater treated). © 2013 Elsevier Ltd.
