Removal of chemical carcinogens from water/wastewater by reverse osmosis (RO)
The removal of chemical carcinogens from water/wastewater by reverse osmosis (RO) was studied in bench-scale experiments on two-membranes, spiral-wound PA-300 and hollow-fiber B-9, and on synthetic wastewaters containing 14 individual chemicals representative of eight groups of organic carcinogens, including aromatic amines, alkyl halides, esters, alkylamines, carboxylic acids, solvents, and detergents. The removal efficiencies of the membranes were high for high-molecular-weight chemicals and low for small polar chemicals such as formaldehyde and ethanol. The removal efficiencies of the membranes were high for high-molecular-weight chemicals and low for small polar chemicals such as formaldehyde and ethanol. The removal efficiencies were >99% for eight chemicals with water solubilities of <100 mg/l., including polycyclic aromatic hydrocarbons and aromatic amines. In studies on a two-stage system that used ultrafiltration through Abcor tubular modules followed by RO, the over-all removal efficiency was above 90%, corresponding to an effluent concentration of <100 jg/l. Wastewaters from three laboratories handling test animals were also studied.
