dc.description.abstractSecondary treated urban wastewater was further polished by reverse osmosis (RO) membranes and the water quality of RO permeates was assessed for their utilizations in agricultural irrigation. The performances of brackish water reverse osmosis (AK-BWRO) and seawater reverse osmosis (AD-SWRO) membranes were investigated at 10 bar as applied pressure. The AD-SWRO membrane was tested also at 20 bar. Conductivity, salinity, chemical oxygen demand (COD), total organic carbon (TOC) and color were rejected by AK-BWRO membrane with average values of 94.6%, 95.2%, 85.8%, 76.4% and 91.3%, respectively, whereas the same contaminants were rejected with average values of 98.3%, 98.3%, 84.6%, 69.7% and 86.6%, respectively with AD-SWRO membrane. Except for TOC, AD-SWRO membrane showed similar rejections at 10 bar and at 20 bar of applied pressures. Although their rejection efficiencies were similar, AK-BWRO and AD-SWRO membranes revealed differences in their permeate flux which is 38.0 L/hm(2) for AK-BWRO membrane and 3.81 L/hm(2) for AD-SWRO membrane. An average value of permeate flux was 14.8 L/hm(2) at 20 bar for AD-SWRO membrane. Assessment of water quality of product water obtained by blending of the two effluents (secondary treated urban wastewater and RO permeate) based on salinity, electrical conductivity, specific ionic toxicity and miscellaneous hazards proved that blending of 20-30% of secondary treated effluent and 80-70% of RO permeate is a good strategy to minimize the unwanted components in treated water for its reuse in agricultural irrigation.
