Ultra-pure water for the battery industry includes ultra-pure water for battery production, ultra-pure water for lithium battery production, ultra-pure water for solar cell production, and ultra-pure water for battery grids. The preparation of electrolyte in batteries has very strict requirements for pure water, It is usually required that the electrical conductivity of water be within0.1us/cmThe resistivity is10Above megohms, the traditional process used to prepare ultra-pure water for batteries often employs anion and cation resin exchange equipment. The drawback of this process is that the anion and cation resins need to be regenerated frequently after being used for a period of time. With the continuous maturation of industrial membrane separation technology, reverse osmosis membrane water treatment processes are now often adopted, or a first-stage reverse osmosis is followed by an ion exchange mixed bed (or electro-deionization)EDIThe process is used to produce ultrapure water.

The process flow for preparing ultrapure water for the battery industry

The processes for preparing ultrapure water in the battery industry can be roughly divided into the following types:

The ion exchange method is adopted

The process is as follows: Source water→Source water booster pump→Multi-media filter→Activated carbon filter→Precision filter→Cation exchanger→Anion exchanger→Mixed ion exchanger→Microporous filter→Water usage point

Adopt reverse osmosis+Mixed bed mode

The process is as follows: Source water→Source water booster pump→Multi-media filter→Activated carbon filter→Softener→Precision filter→Primary reverse osmosis main unit→Middle water tank→Mixed ion exchanger→Microporous filter→Purified water tank→Pure water pump→Water usage point

Electro-deionization is adoptedEDI"Method"

The process is as follows: Source water→Source water booster pump→Multi-media filter→Activated carbon filter→Water softener→Precision filter→Primary reverse osmosis main unit→Middle water tank→EDISystem→Purified water tank→Pure water pump→Water usage point

Characteristics of ultra-pure water equipment for the battery industry

The traditional process for preparing ultrapure water usually employs ion exchange resins for production. However, the use of ion exchange resins typically requires frequent resin regeneration, which not only consumes a lot of material resources but also wastes labor. Our company, after years of practice, has combined the latest reverse osmosis membrane separation technology andEDIThe technology often adopts reverse osmosis technology plusEDIThe equipment is used to prepare ultrapure water. Compared with the traditional process, this process has the advantage of low operating cost and reliable operation. Compared with the new process, it has the advantages of low cost and easy availability of consumables. Reverse osmosis process technology is reliable, and the recovery rate of ultrapure water is greater than90%.
