Abstract

This invention discloses a method and equipment for producing pure water used in pharmaceutical plant, by using membrane separation and electro-deionization, by using urban running water as raw water. The procedures are: low pressure membrane filtration, absorption by activated-carbon, precision filtration, nanometer filtration and softening and desalination, electro-deionization and deep softening, electro-deionization and deep desalination, functional charged membrane filtration. This invention method can remove, from water, inorganic ions, organic pollutants, bacteria, virus and other microorganisms. Compared with prior art process, this inventive process has advantages of: low cost, high utilization rate of raw water, no need of regeneration process, no consumption of alkali and acid, no environmental pollution, wide available of raw water, high reliability and continuous production of high pureness water.

Description

technical field [0001] The invention relates to a method and a device for producing pharmaceutical water through membrane collection separation and electrodeionization, belonging to pure water preparation technology. Background technique [0002] Among the existing processes for preparing medicinal water, there are three representative types: one is the process with ion exchange technology as the core, and the other is the process of combining electrodialysis, reverse osmosis and other membrane technologies with ion exchange. The third is the process with two-stage reverse osmosis as the core. The first two are mainly used for the production of purified water (purified water). The third process is not only able to produce purified water, but also allowed to produce water for injection in some countries. With the continuous development and maturity of membrane separation technology, membrane technology has become the most versatile and economical means of pure water producti...
