Ultrapure water equipment in the battery industry, characteristics and process flow of equipment for

Ultrapure water equipment is required for battery production, and the electrolyte in the battery has very strict requirements for pure water. The electrical conductivity of water is usually required to be above 10 trillion ohms.

Ultrapure water equipment for the battery industry is used in the battery production process, and the battery industry has a high demand for water, so when choosing water treatment equipment, the equipment with the best water quality will be selected, and ultrapure water equipment has become its preferred target.

Characteristics and process flow of battery industry preparation ultrapure water equipment, the raw material that the battery can not do without in the production process is water, but the battery industry is different from other industries, the water quality requirements are very strict, the battery industry uses reverse osmosis ultrapure water equipment to meet the water needs of customers, the following Wanda environmental protection to introduce the characteristics of reverse osmosis ultrapure water equipment, what is the production process.

Ultrapure water equipment for battery industry is a water treatment equipment specially designed and manufactured for the actual water quality of the production of batteries, the ultrapure water equipment runs stably, and the effluent quality meets the actual needs of the battery industry, in line with the relevant regulations of the state for ultrapure water quality standards.

1. No need for acid and alkali regeneration: In the mixed bed, the resin needs to be regenerated with chemical acid and alkali, and EDI eliminates the treatment and heavy work of these harmful substances. Protects the environment.

2. Continuous and simple operation: In the mixed bed, due to the change of each regeneration and water quality, the operation process becomes complicated, while the water production process of EDI is stable and continuous, the production water quality is constant, there is no complex operation procedure, and the operation is greatly simplified.

3. Reduced installation requirements: EDI system has a relatively low volume compared with the mixed bed with a considerable amount of water treatment, and it adopts a building block structure, which can be flexibly constructed according to the height of the site. The modular design makes EDI easy to maintain during production work.

The process of preparing superwater in the battery industry.

First, the ion exchange method is adopted, and the process is as follows: raw water, raw water pressurized pump, multi-media filter, activated carbon filter, water softener, precision filter, positive resin filter bed, anion resin filter bed, yin and yang resin mixed bed, microporous filter, water point.

Second, the two-stage reverse osmosis mode is adopted, and its process is as follows: raw water raw water pressurized pump multi-media filter activated carbon filter water softener precision filter first-stage reverse osmosis pH adjustment intermediate water tank second-stage reverse osmosis (reverse osmosis membrane surface with positive charge) purified water tank pure water pump microporous filter water point.

3. The EDI method is adopted, and the process is as follows: Raw water Raw water pressurized pump Multi-media filter Activated carbon filter Water softener Precision filter First-stage reverse osmosis machine Intermediate water tank Intermediate water pump EDI system Microporous filter Lingdo Water point At present, ultrapure water equipment is an indispensable water treatment equipment for the production of batteries.

The ultrapure water equipment system for the battery industry runs stably, the operation is simple, and the degree of automation is high. Wanda Environmental Protection Water Treatment As a professional water treatment equipment manufacturer, we have a professional technical team, warm and thoughtful service, professional quality assurance, welcome you to visit the factory!

The core components of the ultrapure water machine are the reverse osmosis membrane and the ultra-purification column, buy the imported one, the water quality is good, the consumables are easy to break, and it is expensive. The domestic brand is too miscellaneous, we recommend "Youpu", their core consumables are imported, the pre-treatment is also good, the performance is stable, and the price is cheap.

The decision on the large EDI ultrapure water plant** was based on the following points:

1. The price is different according to the water yield of large-scale EDI ultrapure water equipment selected by users.

2. According to the user's requirements for water purity, the configuration of the selected equipment is different, so it is different.

3. According to the quality of the raw water, the pretreatment equipment selected is different.

4. According to the user's requirements for the degree of automation of the equipment, it is different.

5. According to the user's requirements for the quality of the terminal water, it is different, such as whether it is necessary to add sterilization and disinfection equipment.

6. According to whether the user has requirements for the appearance of large-scale EDI ultrapure water equipment, different materials are selected.

7. According to the user's comprehensive strength, recommend suitable large-scale EDI ultrapure water equipment, and choose different design schemes.

The first class of ultrapure water equipment is composed of its material and process, which is mainly divided into factors such as material, specification, water output, quantity, and process of ultrapure water equipment. The material of ultrapure water equipment is mainly 304 stainless steel and 316 stainless steel, so the raw material **** will be slightly more expensive. The product specification is mainly based on the diameter and size of the equipment, as well as the number of reverse osmosis membranes.

The ** of primary and secondary reverse osmosis is not the same, and the different sizes are also different. And there is a bit of a difference between EDI and ultrapure water resins. Needless to say, the more quantity, the lower the unit price.

The application scope of ultrapure water machine involves hospitals, university scientific research, quality inspection units, chemical plants, pharmaceutical factories, water quality monitoring centers, animal husbandry industry, water plants, disease control centers, seed monitoring stations, battery factories, LCD screen factories, precision circuit factories, dust-free product production, etc.
