I.Overview
Deionization equipment serves as an indispensable “process water purifier” in the chemical industry, with its core value lying in providing high-purity water quality to ensure reaction efficiency, equipment safety, and product quality. It acts as a safety guardian, efficiency enabler, green promoter, and quality foundation.
Selection principles: For highly corrosive conditions, choose PVDF/titanium piping; for high COD water sources, pair with O₃ + activated carbon pretreatment; for large-scale projects, use CEDI to replace mixed-bed systems (saving 85% in operational costs).
II.Main Process
Chemical Wastewater/Surface Water→Enhanced Pretreatment→Fouling - Resistant RO→CEDI→ DI Water for Chemical Use

V.Here is a guideline for you to get a proper quotation
Tell us the raw water/source of water(tap water, well water, or sea water, etc)
Provide water analysis report(TDS , conductivity, or resistivity, etc)
Required production capacity( 5m³/H, 50m³/H,or 500m³/H, etc)
What's the pure water used for( industrial,Food and Beverage,or agriculture, etc )
