What issues need to be known about reverse osmosis pure water equipment for battery production?(1)

- Jan 15, 2021-

The raw material for battery production is pure water. The ultrapure water used in the battery industry includes ultrapure water for battery production, ultrapure water for lithium battery production, ultrapure water for solar cell production, and ultrapure water for battery grids. Pure water. But the battery industry is different from other industries. It has very strict requirements for water quality. The emergence of reverse osmosis ultrapure water equipment in the battery industry has greatly met the demand for water for battery production. The reverse osmosis system is now the core part of ultrapure water equipment. For the safe use of water, the product water is based on the conductivity and resistivity data. The smaller the conductivity, the purer the water, the greater the resistivity, the purer the water. The product water required by the battery requires a resistivity of ≥10mΩ.cm².The following briefly introduces the characteristics of reverse osmosis ultrapure water equipment:


There are three ways in the system process, depending on the water usage.

Adopt the first-level reverse osmosis methodRaw water point-raw water pump-pretreatment device (quartz sand filter, activated carbon filter, water softener, precision filter)-one-stage reverse osmosis system-one high-pressure pump-over-flow ultraviolet sterilizer-pure water point.


Adopt a secondary reverse osmosis methodRaw water point-raw water pump-pretreatment device (quartz sand filter, activated carbon filter, water softener, precision filter)-primary reverse osmosis system-primary high pressure pump-secondary reverse osmosis system-secondary high pressure pump-pass Flow UV Sterilizer-Pure Water Point.


Adopt reverse osmosis + EDI system approachRaw water point-raw water pump-pretreatment device (quartz sand filter, activated carbon filter, water softener, precision filter)-primary reverse osmosis system-primary high pressure pump-secondary reverse osmosis system-secondary high pressure pump-pass Flow UV Sterilizer-EDI Device-Overflow UV Sterilizer-Pure Water Point.
