【Overview】
Battery industry, including battery with ultra-pure water used in the production of pure water, pure water production of lithium batteries, solar cells, production of pure water, battery box plate with pure water. Electrolyte batteries with very strict requirements on the water, the conductivity of the water normally required in 0.1us/cm (10 megohm resistance) or more, the traditional use of ultra-pure water used to prepare the battery technology is often used resin yin and yang Switching equipment, the shortcomings of the process is in use for some time after the resin should always renewable. With the membrane separation technology continues to mature, now often use reverse osmosis filtration, reverse osmosis or later and then after using a mixed bed ion exchange (or electrodeionization EDI) technology to obtain ultra-pure water system.

【Applications】
Battery production of pure water production,
Lithium water extraction,
Water, solar photovoltaic industry,
Dry batteries, production of pure water
【Solutions】
Preparation of super water in the battery industry processes roughly divided into the following categories：
1, the use of ion exchange, the process is as follows：
Raw water Raw water pressure pump → → → Multi-media filter activated carbon filter precision filter → → → softener cation resin anion resin filter bed filter beds → → → yin and yang, the mixed bed resin filter pore water points →
2, two-stage reverse osmosis methods, the process is as follows：
Raw water Raw water pressure pump → → → Multi-media filter activated carbon filter softener → → → precision filter regulator first stage reverse osmosis → PH → intermediate → the second stage tank reverse osmosis (RO membrane surface with positive charge) → Purification of pure water tank → → Pumps → micropore filter water points.
3, the use of EDI methods, the process is as follows：
Raw Water Pumps → → raw water pressure multi-media filter activated carbon filter → → → precision filter water softener reverse osmosis machine → intermediate → an intermediate pump water tank → → → EDI system → microporous filter water points.
