PLC Control Skid Mounted EDI Water Purification System for Industrial Applications

This PLC Control Skid-mounted Integrated EDI System is a complete pre-assembled industrial deionized water treatment solution designed for general industrial factories, manufacturing plants, and industrial park centralized water supply projects. Unlike traditional scattered water treatment equipment, this skid-mounted EDI unit integrates membrane stack, pipeline circuit, intelligent control cabinet, monitoring instruments, and protection devices on a unified base, enabling plug-and-play installation and one-piece delivery.

When matched with two-stage RO pretreatment, the equipment performs deep deionization purification, effectively removing residual minerals, tiny impurities, and conductive substances from water. Operating in a fully automatic non-chemical mode, it consistently delivers high-purity industrial deionized water 24/7. With its highly integrated structure, intelligent operation, and low on-site construction costs, this system represents an optimal upgraded water treatment solution for standardized industrial factory production lines.

After purification by the two-stage RO system, qualified inlet water steadily enters the integrated skid-mounted EDI membrane stack. Under a continuous and stable DC electric field, the internal high-efficiency ion exchange resin adsorbs residual trace ions and micro impurities from the water.

Impurity ions achieve directional separation through selective ion exchange membranes and are concentrated and discharged through independent water channels. The system automatically regenerates internal resin during operation without chemical addition, eliminating frequent manual maintenance. Equipped with an integrated PLC intelligent control system, the entire unit automates water intake, circulation, flushing, and water quality monitoring.

The controller dynamically adjusts operating voltage and flow parameters based on real-time water quality changes, ensuring long-term stable and consistent high-purity water output for industrial production.

• Skid-Mounted Integrated Design: All core components and auxiliary parts are pre-assembled on an integral base, enabling overall delivery, simple on-site installation, no complex pipeline layout, and significant savings in construction cycle and site costs.
• Full PLC Intelligent Automatic Control: Equipped with industrial-grade PLC control system supporting automatic operation, real-time data display, parameter self-adjustment, and fault self-detection for 24-hour unattended operation.
• Non-Chemical Green Running Mode: Electric automatic resin regeneration without chemical dosing, no auxiliary consumables, and no waste liquid emission, meeting modern industrial energy-saving and environmental standards.
• Stable Industrial-Grade Water Quality: High-precision stacked EDI membrane stack ensures high desalination efficiency, effectively removes trace conductive impurities, and consistently supplies high-resistivity deionized water.
• Space-Saving & Compact Structure: Highly integrated layout reduces redundant structure, minimizes overall footprint, and enables flexible placement suitable for factory workshops with limited installation space.
• Low Operation & Maintenance Cost: Intelligent energy-saving operation program reduces power consumption, while integrated modular structure simplifies daily maintenance with low failure rate and long service life.
