Battery pure water treatment process is roughly divided into the following kinds:
　　1.Using ion exchange way, the process is as follows:
　　Raw water, raw water pump to many medium filter, activated carbon filter, water softener to the precision filter, Yang resin filter bed to Yin resin filter bed, mixed bed resin of Yin and Yang - microporous filter - water points
　　2.Using two-stage reverse osmosis, the process is as follows:
　　Raw water, raw water pump to many medium filter, activated carbon filter, water softener to the precision filter, the first-level reverse osmosis - > PH adjustment to the middle water tank, the second ro (reverse osmosis membrane surface is positively charged) to purified water, pure water pump - microporous filter - water points
　　3.Using EDI way, the process is as follows:
　　Raw water, raw water pump to many medium filter, activated carbon filter, water softener, the precision filter - level 1 reverse osmosis machine - the middle water tank - intermediate water pump - EDI system - microporous filter - water points
