HFX-55d Rinsewater Recycling System at American Standard Circuits, Inc

In June 2010, ASC-I of West Chicago installed a HFX-55d Ion Exchange System to recycle rinsewaters generated at their facility. Built by Water Innovations, Inc. (WI) of San Diego, CA and sold by Environmental Compliance, Inc. (ECI) of Elk Grove Village, the turn-key project was completed within 8 weeks of PO on a flexible schedule while ASC-I continued manufacturing activities.

The 4-skid modular system with a central controller is mounted on 316 stainless steel frames. Highly-efficient, it supplies 0.2 µS/cm DI water to 65% of production rinsewaters through closed-loop recycling while generating only 5% waste. The HFX-55d has reduced loading on the conventional treatment system by 45 gpm, will save approximately $15,000 per month on water and sewer costs, and enabled elimination of Service exchange DI (SDI). The return on investment will be 24 months or less.

The HFX55d system utilizes duplex components throughout, providing 100% redundancy to ensure its full-time operation. On separate skids, one each of the cation and anion resin vessels are in service while the other set of vessel are either in stand-by or regeneration. Duplex system feed and process supply pumps protect against unanticipated failure of one and extend the service life of both through alternating use. Interconnect piping is Schedule 80 PVC with primarily union and flange fittings, and corrosion-resistant 304 stainless steel mounting hardware is used. System operation is automatic or manual with a 6” color touch screen illustrating system flows and providing real-time data on system operation.

Independent regenerations of the cation and anion vessels are fully automatic, utilizing feed forward grain counting, with packed-bed resin columns for the highest quality water and regeneration efficiency. Carbon backwashing is automatic based on time of operation or gallons processed. Operator responsibilities are limited to periodic bag filter change-outs and verifying the availability of regeneration chemistry. Otherwise, the system operates entirely automatically.
