Regenerable Ion Exchange Water Recycling Systems
Water Innovations Regenerable Ion Exchange Water Recycling systems (WI-RIX-WR) are engineered for efficient water purification and recycling, offering continuous operation and high-quality deionized (DI) water.
Both the WI-RIX-12-WR and WI-RIX-25-WR systems feature a skid-mounted design, utilizing a 304SS skid coated with polyurethane to prevent corrosion. Installation is minimized, generally limited to interconnect piping and electrical connections. Both systems operate continuously using an alternating duplex configuration for the cation and anion exchange vessels, ensuring that one set is always in service while the other is in regeneration or standby.
