This integrated two-stage reverse osmosis plus EDI deep desalination system is specially designed for electronic manufacturing. It thoroughly removes soluble salts, micro-particles, organics and microorganisms from raw water. No acid and alkali chemical regeneration is required during operation. The produced ultra-pure water reaches ultra-high purity standard, effectively avoiding electronic product short circuit, blemish and poor conductivity caused by ionic impurities, perfectly matching wafer, circuit board, chip and precision electronic production.

Raw water tank → Raw water pump → Quartz sand filter → Activated carbon filter → Water softener → Anti-scalant dosing device → 5μm security filter → First-stage high-pressure pump → First-stage RO system → Intermediate water tank → Second-stage high-pressure pump → Second-stage RO system → EDI deep desalination stack → Ultrapure water tank

• Double-stage RO: Mass desalination to reduce total salt content and protect EDI from organic fouling
• EDI stack: Deep deionization to produce high-resistivity ultra-pure water
• Optional post-processing: UV sterilizer, polishing mixed bed to further reduce bacteria and micro-particles

• Semiconductor wafer etching, cutting and cleaning process water
• PCB circuit board development, electroplating and washing water
• Chip packaging, microelectronic component precision cleaning
• LCD panel, lithium battery production ultra-pure water supply
• Electronic laboratories, precision testing instrument supporting ultra-pure water

Adjust equipment flow rate and add polishing filters according to factory water quality and production standards.

Core spare parts including high-pressure pumps, PLC control system, RO membranes and EDI modules enjoy one-year warranty. Lifelong free technical support is available for installation, debugging and daily maintenance.

We supply operation manuals, layout drawings and overseas remote commissioning guidance for global buyers.
