Industrial RO EDI Water Purification System For Ultra Pure Water Making

This integrated water treatment equipment combines reverse osmosis host and EDI continuous electrodeionization module, specially designed for producing high-standard industrial ultra-pure water. It effectively removes salt ions, organics, colloids and microorganisms in raw water without chemical regeneration, meeting strict water quality requirements for electronics, pharmacy, laboratory, electroplating and new energy industries.

• Superb Ultra-pure Water Quality
  Two-stage RO removes most dissolved solids first, then EDI deeply purifies residual ions. The produced water resistivity can reach 15-18.25MΩ*cm, fully satisfying high-end production standards.
• No Chemical Regeneration, Eco-friendly
  Unlike traditional mixed bed resin, EDI module works continuously without acid and alkali dosing for regeneration. It reduces chemical waste discharge and simplifies daily operation.
• Stable 24-hour Automatic Operation
  Equipped with PLC touch screen automatic control system, it supports automatic flushing, real-time monitoring of water conductivity, resistivity, pressure and flow. Fault self-alarm function ensures unattended running.
• Compact Skid-mounted Structure
  RO host and EDI unit are integrated on one stainless steel frame, occupying small workshop space. The whole set is pre-assembled for quick on-site installation and commissioning.
• Low Operating Cost
  High water recovery rate lowers raw water consumption. EDI only consumes low power, saving long-term chemical and labor maintenance expenses.

Raw water tank → Raw water pump → Quartz sand filter → Activated carbon filter → Water softener → Anti-scalent dosing system → 5μm security filter → High pressure pump → Two-stage RO system → Intermediate water tank → EDI ultra-pure water module → Ultrapure water tank

• Two-stage RO: Primary desalination to eliminate most salts, protect EDI module from fouling
• EDI Module: Deep ion exchange to get high-resistivity ultra-pure water
• Optional post equipment: UV sterilizer, precision polishing filter to further reduce bacteria and particles

Customized water output ranges from 0.5 to 50 cubic meters per hour. The single RO membrane desalination rate exceeds 98%. The finished ultra-pure water resistivity can reach 15-18.25MΩ*cm. The system total water recovery rate is kept at 70% to 80%.

Anti-fouling 8040 RO membranes are adopted as standard, matched with industrial grade EDI stacks. The whole pipeline and frame use 304 or 316 stainless steel to avoid secondary pollution.

Working temperature ranges from 10℃ to 40℃, standard power supply is 380V/50Hz with supporting power configured based on actual water yield.
