Hyperfiltration Processes for Treatment and Renovation of Textile Wastewater

摘要

The report describes a computer program developed for the design and simulation of a multistage hyperfiltration system for renovation of textile wastewater. The program is capable of practical design, parametric simulation, and cost projection of the multistage hyperfiltration system with tapered inner stages. The mathematical model is based on Sourirajan's preferential sorption and solute diffusion theory. Experimental rejection and flux data of a test hyperfiltration module are required as inputs. Empirical correlations and test results available from recent EPA-sponsored programs are used to calculate membrane transport parameters. Computer results for sample cases using cellulose acetate and dynamic membranes are presented. Various designs and operations are considered in the computations to show their effects on system economics. The program is readily adaptable for evaluation of other reverse osmosis/hyperfiltration applications.
