Overview of Ultra Pure Water Used in the Battery Optics Industry
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. The preparation of electrolyte in batteries requires very strict requirements for pure water, usually requiring a conductivity of 0.1us/cm (resistivity of 10 megaohms) or higher. The traditional process for preparing ultrapure water for batteries often uses cation exchange equipment, but the disadvantage of this process is that the cation exchange resin needs to be regenerated frequently after a period of use. With the continuous maturity of industrial membrane separation technology, reverse osmosis membrane water treatment process is often used, or first stage reverse osmosis followed by ion exchange mixed bed (or electro deionization EDI) process is used to produce ultrapure water.

Introduction to reverse osmosis equipment:

Reverse osmosis equipment uses advanced reverse osmosis desalination technology internationally to prepare deionized water, which is a purely physical process preparation technology. The reverse osmosis pure water unit has the advantages of long-term uninterrupted operation, automatic operation without the need for special supervision, simple operation, long-term stable water quality, no pollutant emissions, and low cost of producing pure water. The core component of the reverse osmosis pure water unit, the reverse osmosis (RO) membrane, adopts a domestically imported famous brand roll type composite membrane, and the high-pressure pump also uses imported products from famous brands. The system is equipped with a pre-processing system, such as activated carbon adsorption filters and precision security filters. In terms of electrical and automatic control, it is equipped with a pressure automatic protection system and a water quality automatic online monitoring instrument system, making the equipment control system clear at a glance. It also has a front-end inlet pressure boosting and a back-end water tank level linkage interface.

1、 Overview of Industrial Reverse Osmosis Water Treatment Equipment:
The reverse osmosis water treatment equipment is assembled using the most advanced reverse osmosis membrane elements, high-pressure pumps, instruments, and dosing metering pumps produced domestically and internationally. The support pipelines and other auxiliary components in reverse osmosis devices are mainly produced domestically. The main performance of the reverse osmosis equipment has reached the advanced level abroad. This product is designed and manufactured by our unit in a series, and various types of reverse osmosis membranes can be selected according to the different engineering needs of users to design a reverse osmosis desalination device that is more suitable for your engineering needs. We welcome customers to choose.

2、 Principle of reverse osmosis pure water equipment:
Reverse osmosis is a membrane separation process powered by pressure gradient, which, like a molecular filter, can effectively remove dissolved salt colloidal bacteria and organic matter from water. The reverse osmosis process is the reverse process of natural osmosis. In order to generate the reverse osmosis process, a water pump is needed to apply pressure to the saline solution to overcome its natural osmotic pressure, so that water can pass through the reverse osmosis membrane and prevent dissolved salts and other impurities in the water from being trapped on the other side of the reverse osmosis membrane; At the same time, in order to prevent the concentration of dissolved salt impurities in the raw water from focusing on the membrane surface, the concentrated water should continuously wash the membrane surface during operation and carry out the impurities in the concentrated water and on the membrane surface to achieve the entire process of reverse osmosis desalination purification.

3、 Functions of reverse osmosis pure water equipment:
Advanced reverse osmosis technology is used for pre desalination, resulting in a reduction of over 98% in the system's acid-base consumption and a significant decrease in branch fees. Imported high-pressure pump with high efficiency, low noise, and excellent quality. The imported online raw water and product water conductivity meter pH meter can monitor water quality at any time. Imported online product water and concentrated water flow meters, concentrated water reflux flow meters can monitor the water volume of each product at any time, and the system recycling vehicle.
4、 Operating parameters of reverse osmosis pure water equipment: desalination rate:
The desalination rate of the reverse osmosis system is 98%;
Operating pressure -1Mpa to 1.5Mpa;
Recovery rate: 75% to 80%.

5、 Advantages of reverse osmosis pure water equipment:
1. RO machine design recovery rate>75%;
2. RO inlet low pressure protection to prevent the high-pressure pump from running idle due to water shortage;
3. The RO system automatically flushes upon startup and runs continuously for 1 hour;
4. The RO system automatically shuts down during pre-treatment regeneration and backwashing; The raw water pump automatically starts;
5. The RO machine automatically shuts down when the water level in the raw water tank is low or when the water level in the pure water tank is high, and automatically starts up when the water level in the pure water tank is low;
6. Set fault alarm indication;
7. The built-in PLC has a light indicator, making maintenance easier.
