(I) Product Overview
This set of ultra pure water preparation equipment is developed for high-end manufacturing fields such as lithium batteries and precision electronics, with dual stage reverse osmosis (RO)+EDI electro deionization as the core processing technology. The equipment can stably produce high-grade ultrapure water with a resistivity of ≥ 18M Ω· cm. The effluent water quality is pure and the indicators operate stably, fully adapting to the water standards of strict production processes such as electrolyte preparation and electrode coating. The whole machine is equipped with a fully automatic intelligent control system, which realizes unmanned and automatic operation throughout the entire process, and has the characteristics of energy saving, water saving, and low maintenance costs in the later stage; We can customize the water production scale and process configuration according to the on-site raw water conditions, and flexibly adapt to diverse working conditions.
(II) Core features of the product
1. Deep desalination purification and continuous stable effluent quality equipment are equipped with imported reverse osmosis membrane components from Dow and Heideneng, matched with high-precision EDI membrane stacks. The overall ion removal efficiency exceeds 99.99%, and it can stably produce 18M Ω· cm grade ultrapure water for a long time, effectively suppressing water quality fluctuations and fully meeting the strict water consumption requirements of high-end manufacturing industries.
2. Fully intelligent automatic operation, energy-saving and cost control, equipped with PLC intelligent control system, realizing functions such as online water quality monitoring, automatic flushing, fault prompt, and automatic adaptation of operating parameters, without the need for manual on-site supervision. Equipped with frequency conversion and energy recovery components, it saves 25% and 30% energy compared to traditional water production equipment, with a water recovery rate of up to 70%, significantly reducing long-term operational investment.
3. Integrated modular construction, adaptable to various working conditions. The whole machine adopts a standardized integrated module architecture, and pre-processing, reverse osmosis, and EDI units can be flexibly matched according to the water production scale. The equipment structure is compact, and on-site installation and debugging are simple and efficient. In the face of complex raw water quality such as high hardness and high organic matter, customized water treatment solutions can be provided to adapt to diverse industrial application scenarios.
4. Durable and easy to maintain, the key components of the green production waterway are made of 316L stainless steel and high-performance anti-corrosion UPVC material, and the designed service life of the whole machine can reach more than 10 years. The EDI unit abandons the acid-base reagent regeneration process and produces no acid-base waste liquid; Equipped with automatic cleaning of membrane components and reminders of consumables expiration, it extends the service life of components and reduces daily maintenance workload.
(III) System composition and core functions
1. The preprocessing system is composed of a multi-media filter, activated carbon filter, softening device, and precision security filter. Gradually filtering out sediment, colloids, organic matter, and residual chlorine from the raw water, reducing the hardness of the inlet water, intercepting various fine impurities, adjusting the inlet water quality to the allowable working conditions of reverse osmosis, and playing a key protective role in the back-end reverse osmosis membrane components.
2. The two-stage reverse osmosis RO system is equipped with imported high-pressure reverse osmosis membrane elements. Based on the principle of high-pressure reverse osmosis screening, it can remove dissolved salts, suspended solids, and microorganisms in water on a large scale, produce low conductivity primary pure water, complete the main desalination process, and provide qualified inlet water source for the EDI deep refining unit.
3. The EDI electro deionization system, as the core unit for deep refining of the entire equipment, utilizes the synergistic ion exchange effect of a direct current electric field to further remove trace ions remaining in the water; Without the need for acid-base agents for chemical regeneration, it can sustainably and stably produce 18M Ω· cm grade ultrapure water, which is the core module for the production of industrial electronic grade ultrapure water.
4. The terminal sterilization and filtration system is equipped with dual wavelength ultraviolet sterilization equipment and terminal precision filters, which can inactivate water microorganisms, decompose some organic pollutants, intercept fine solid particles, avoid secondary pollution caused by pipeline transportation, and ensure the sterility and high purity of the final effluent.
5. The intelligent self-control system uses industrial PLC combined with human-machine touch screen as the control center to real-time collect key operating parameters such as flow rate, pressure, water quality, etc; Integrate multiple functions such as automatic flushing, water shortage and overpressure protection, fault alarm, and operation data storage to ensure that the equipment can operate continuously and stably without human supervision for 24 hours.
