Abstract

The present invention discloses an inexpensive import substitute compact design of low-cost membrane process for the production of ultrapure water for dialysis and medical applications in different fields like pathological laboratories, biochemical analysis, sterilization and sanitation, dental and optical lens cleansers. The ultrapure water of demineralization (DM) process is related to the cascaded high- flux and high-selective membrane system for hyper permeation which is operated under the pressure of 3-7 kg/cm2 to generate DM water with total dissolved solids (TDS) of 0−2 ppm. The DM water system is designed for a capacity in the range of 25–60 L/h capacity and its salient features include compact design of the membrane assembly with higher effective membrane area per unit volume to ensure higher DM water recovery at relatively lower pressure compared to the existing reverse osmosis (RO) membrane system. The process pertaining to the present invention is more economical, low maintenance and highly effective compared to the conventional demineralization and more expensive demineralization membrane units currently available in the market. The configuration of the membrane modules adapted in the present invention is simple, easy to operate and useful for several biotechnological, biochemical, medical, and industrial applications shown as graphical sketch figure1.
