Mixed Bed Polishing Ultrapure Water Equipment 18.25MΩ·cm Resistivity Automatic

This post-RO mixed bed polishing ultrapure water equipment serves as a terminal deep polishing unit specifically designed to follow single-stage or two-stage reverse osmosis systems. Utilizing high-purity anion and cation mixed ion exchange resin, it deeply removes trace residual soluble salts, silica, boron, and micro ionic impurities that RO membranes cannot fully eliminate.

The system significantly improves outlet water resistivity, consistently producing 15-18.25MΩ*cm high-purity ultrapure water. It effectively addresses water conductivity issues caused by raw water fluctuations and serves as essential polishing equipment for semiconductor, pharmaceutical, new energy battery, laboratory, and electroplating ultrapure water production lines.

• RO produced pure water flows evenly into the mixed bed tank, passing through fully mixed cation & anion exchange resin layers
• Cation resin adsorbs residual metal ions such as calcium, magnesium, and sodium; anion resin absorbs sulfate, chloride, silicate, and borate radicals simultaneously
• Trace weak electrolytes and soluble silicon that penetrate the RO membrane are thoroughly captured, significantly increasing water resistivity
• When resin adsorption reaches saturation, the system performs automatic backwashing, layered separation, acid & alkali regeneration, forward washing, and resin mixing to restore full exchange capacity
• Polished ultrapure water flows out through precision terminal filters to intercept resin fine particles, preventing resin leakage to subsequent production equipment

• Excellent Terminal Polishing Effect: Compensates for limited reverse osmosis desalination capacity with outlet resistivity steadily reaching 18.25MΩ*cm, controlling silicon and boron content at ultra-low levels to meet high-end industrial standards
• Flexible Regeneration Configurations: Manual small mixed bed for laboratory low-flow scenarios; fully automatic duplex mixed bed with automatic regeneration cycles for large industrial production lines, enabling uninterrupted continuous water supply
• High Purity Imported Ion Exchange Resin: Food/electronic grade high-efficiency mixed resin with large exchange capacity, long service cycles, low residual ion leakage rates, and stable long-term polishing performance
• Corrosion-resistant & Sanitary Tank Options: 304/316L stainless steel vertical tanks or FRP anti-corrosion tanks available, preventing secondary pollution and suitable for pharmaceutical sanitary workshops and corrosive electroplating environments
• Compact Structure & Easy Installation: Direct connection behind existing RO systems without extensive pipeline reconstruction, ideal for equipment upgrades and new production line integration
• Low Operation Cost: Minimal consumption of hydrochloric acid and sodium hydroxide during regeneration, with low daily power and water consumption for economical long-term industrial use

• Post-processing polishing for semiconductor chip cleaning ultrapure water systems
• Two-stage RO supporting polishing equipment for pharmaceutical sterile water production
• New energy lithium battery factory EDI system backup high-purity polishing units
• Laboratory and research institute small ultrapure water terminal refining devices
• Electroplating high-gloss coating deionized water post-treatment equipment
• Cosmetic high-end formula water and bottled pure water deep purification units
