Abstract : The feasibility of using synthetic membranes in an ultrafiltration process for recovering potable water from urine was demonstrated with urine specimens which had been enzymatically treated and acidified with citric acid. Specially cast cellulose acetate membranes were used in an experimental ultrafiltration system to reclaim waters which met the United States Public Health Service specifications on chloride ion and total dissolved solids. The product water was obtained at initial flux rates of approximately 10-20 liters per square foot of filtration surface per day at operating pressures of approximately 2000 pounds per square inch. A proposed design of an ultrafiltration unit is included along with a comprehensive discussion of the engineering considerations deemed significant. (Author)
