Investigation and Technique of Calculating the Effective Operation Life of Semipermeable Membranes in Ultrafiltration Purification of Industrial Solutions

Abstract

The design of a newly developed membrane device and technique of calculating the effective operation life of semipermeable ultrafiltration membranes by means of which the length of the period of effective realization of the process of purification, concentration and demineralization of industrial solutions may be determined is presented. In the newly developed technique, the estimated length of the effective life of ultrafiltration membranes under different conditions of the industrial purification process, which varies from 96 to 125 hours, is determined. Computed average calculated values of the diffusion coefficients in ultrafiltration membranes and the maximum contact stresses are presented.
