Description
This study aimed to investigate the effects of coexisting substances on separation of endocrine disrupting chemicals (EDCs) in water and domestic wastewater effluents using low pressure reverse osmosis (LPRO) membrane. The coexisting substances included calcium chloride, glutamic acid sodium salt, acetic acid and humic substances whose molecular weight ranged up to twenty thousand. The results showed higher rejection of nonylphenol in a mixed solution of the coexisting substances. Thus, the results indicated that coexisting substances can affect rejection properties of EDCs in LPRO membranes. In using higher desalting membranes, much higher rejection rates of EDCs in domestic wastewater effluents were observed compared to rejection of a single solution, which shows over 95% rejection. However, rejection of E2 from domestic wastewater did not increase with relatively loose membrane.
