Closed Loop Water DI System Design

Deionised (DI) or Demineralised (Demin) water systems use resin technology to remove dissolved ions from water, producing a consistently high-purity supply. Standard DI systems typically achieve less than 5 µS, while mixed bed systems can reach 0.5 µS for polishing applications. By operating as a closed loop, these systems recirculate water to reduce waste, lower operating costs, extend the life of chemical processing solutions, ensure quality finishand meet warranty applicator standards. In industries such as powder coating, closed-loop Serviced DI (SDI) systems also support zero-discharge operations, eliminating the need for sewer discharge and effluent treatment plants.

Ryonex provides end-to-end closed-loop DI solutions, including system design, professional installation, commissioning, and operator training. Our SDI systems supply DI rinse water across all rinse tanks, protecting non chrome solutions, extending bath life and ensuring quality finishing. With the added benefit of outsourced resin regeneration, businesses gain the assurance of high-quality DI water while maintaining sustainable, compliant, and cost-efficient operations.
