Product Description

90M³/h Industrial RO EDI Water System For Power Electronics And Chemical Industry

System Overview

This 90 m³/h industrial reverse osmosis (RO) system delivers high-quality water for industrial processes requiring ultra-pure or high-purity water. Ideal for power generation, electronics, chemical production, pharmaceuticals, and beverage manufacturing, the system integrates pretreatment, RO, EDI (Electrodeionization), and filtration to ensure stable, reliable water quality.

EDI (Electrodeionization) combines ion exchange resin with electrodialysis membranes to continuously produce high-purity water with resistivity up to 18 MΩ*cm or higher. As a core component of ultra-pure water production, EDI represents the transition from chemical regeneration to continuous physical purification. In semiconductor and pharmaceutical industries, EDI has replaced mixed-bed systems as the industry standard (SEMI F63).

Main Process Flow

Raw Water → Raw Water Tank → Booster Pump → Flocculant/Reducer Dosing → Activated Carbon Filter → Ultrafiltration (UF) → Scale Inhibitor Dosing → Security Filter → 1st Stage High-Pressure Pump → 1st Stage RO → pH Adjustment → Intermediate Tank → 2nd Stage High-Pressure Pump → 2nd Stage RO → Purified Water Tank → EDI Booster Pump → UV Sterilizer → Cartridge Filter → EDI System → Ultra-Pure Water Tank → Transfer Pump → TOC Removal Unit → Polishing Resin → Final Filter → Point of Use

Unit Functions

Multi-Media Filter: Removes suspended solids, sediment, rust, and turbidity to protect downstream RO membranes and equipment
Activated Carbon Filter: Removes residual chlorine, organic matter, color, and odor to prevent oxidation or fouling of RO membranes
Precision Filter (5 μm or finer): Further removes fine particles to protect RO system
Reverse Osmosis (RO) System: High-pressure pumps force water through RO membranes, removing dissolved salts, heavy metals, microorganisms, and colloids with salt rejection ≥ 98%
EDI Module (Electrodeionization): Continuously removes residual ions without chemical regeneration, producing high-purity water with stable conductivity (1-5 μS/cm)
Pure Water Tank & Circulation System: Ensures stable water supply with circulation pump to maintain flow and prevent water quality deterioration

Core EDI Components and Materials

Component	Material and Function	Industry Standard
Ion Exchange Resin	Nuclear-grade granular resin (e.g., Purolite® NRW1600), particle size 0.6-0.7 mm, exchange capacity ≥ 1.8 eq/L	ASTM D1782
Ion Exchange Membrane	Perfluorosulfonic acid membrane + perfluoroquaternary ammonium membrane (e.g., DuPont Nafion®), ion selectivity > 98%	SEMI F73
Diaphragm Flow Channel	Food-grade PP or PVDF, thickness 0.8-1.0 mm, turbulent flow design to prevent scaling	FDA 21 CFR 177
Electrode	Titanium-plated ruthenium anode/stainless steel cathode, corrosion-resistant current density > 100 mA/cm²	ISO 9001

Operational Guidelines

Raw Water Quality Monitoring: Regularly check hardness, residual chlorine, and turbidity to prevent scaling or RO membrane damage
RO System Protection: Low-pressure protection to prevent pump dry running; high-pressure protection to prevent membrane damage; periodic membrane flushing to reduce fouling
EDI Module Operation: Ensure stable RO permeate water quality; avoid high hardness or high CO₂ content entering EDI; monitor conductivity for stable water quality
Circulation System Maintenance: Prevent stagnation and microbial growth; regularly disinfect and clean tanks and pipelines
Automatic Control & Alarm System: PLC automatically manages start/stop, flushing, and alarms; immediate response to abnormal conditions ensures safe operation
