Summary

A laboratory reverse osmosis system capable of purifying 4 liters of a mixture of 2.4 liters of urine and 1.6 liters of either wash or dehumidification water in a 24-hour period was fabricated. The quantitative rejection of urea by the membranes was found to be the major problem. Urea rejection by complexing urea with various chemicals was investigated but no significant increase was realized. The effect of storage conditions on membrane performance was investigated. A study was made of the annealing of cellulose acetate membranes and attempts were made to develop satisfactory benzyl derivatives of cellulose acetate. A method was developed which permitted a rapid evaluation of membrane performance. A satisfactory membrane was found to result from the precise control of the annealing process.
