Pure Water Equipment

The combination of Electrodialyzer&ion-exchangers is an ideal device for battery factories to produce purewater. Economic and stable and easy in operation, with a long purewater-preparation period and thus a long service life,the output of purewater by the combination is great,the quality high and stable and the cost is low(one forth or one fifth of that by ion-exchangers only).

If the quality of the purewater produced by the electrodialyzer needs to be further improved,we can adopt a combination of electrodialyzer and ion exchangers to meet the requirement.

Electrodialyzer, is a stable and effective desalter whose desalination ratio is higher than 80%.Generally speaking,the quality of the output purewater produced by the electrodialyzer can meet the requirement of battery factories for use.According to selective permeability of electrodialysis membrane,it makes positive ions and negative ions in the original water gathering respectively to positive membranes and negative membranes under electric-field stress impressed.Desalted water thus forms between positive membranes and negative ones.

Reverse Osmosis Equipment employs a latest separated-by-membrane technology developed in 1990s. According to the osmosis principle of the semipermiable membrane,a reverse-osmosis pressure (stronger than osmosis pressure)exerted to the original water will force the contained dissolvant water permiating through RO membranes against the natural osmosis pressure,producing qualified purewater.
