Contents Notes Pilot scale tubular and spiral wound Reverse Osmosis (RO) units were used to establish the feasibility of renovating municipal sewage. Results indicated that prior treatment with ferric chloride and alum will be necessary even when using the tubular RO system. RO produced an approximate 100 mg/ TDS of inorganic ions in the effluent, but an estimated 40 to 50% of the soluble organic material permeated the membranes at high feed water recoveries. Approximately 70% of the organic material passing the membrane was ethanol, but other organics may pass through the membranes from other sewages. 92% water recovery rates, with no precipitation problems in the RO concentrate, were achieved, but RO product waters would require further treatment for organic removal prior to discharge. The feasibility of biodegrading RO concentrates was also established.
