Two-Pass RO + EDI Ultrapure Water Process

This two-pass RO EDI ultrapure water system uses municipal tap water as the raw water source. Water first passes through quartz sand filtration, activated carbon filtration, and precision filtration to remove sediment, rust, colloids, residual chlorine, organic matter, and larger particles. This pretreatment stage protects the RO membrane modules and improves system stability.

After pretreatment, water enters the two-pass reverse osmosis section. The double-stage RO process removes most dissolved salts, heavy metals, bacteria, and microorganisms, producing high-purity water for further polishing. The EDI module then continuously removes trace ions, silicates, and residual electrolytes without large acid and alkali regeneration consumption.

At the final stage, the system is equipped with polishing mixed bed, UV sterilization, and terminal ultrafiltration to further improve water purity and cleanliness. The complete system supports automatic return flow, pressure stabilization, and continuous high-purity water production.

Integrated Industrial EDI Water System

The equipment integrates pretreatment tanks, two-pass RO membrane groups, EDI modules, polishing mixed bed, UV sterilizer, PLC electric control cabinet, online water quality instruments, and 316L sanitary piping. The frame uses anti-corrosion painted carbon steel, and the water-contact piping is designed with 316L stainless steel.

The system supports automatic flushing, automatic regeneration, fault self-checking, alarm functions, and 24-hour continuous water production according to site operation requirements. Compared with traditional mixed-bed water production, the EDI-based process is easier to operate and more environmentally friendly.
