These units can generate a water quality greater than 1,000,000 ohm/cm based on inlet quality, and use a duplex configuration. If set up correctly 50% of resin will remain in reserve or in regeneration. Regeneration is initiated by measuring feed water quality and flow rate.
Water pressure is used to drive all valve functions.
To regenerate the cation vessel there are three steps; Acid draw, slow rinse, and fast rinse.
To regenerate the anion vessel there are four steps; Stand by tank purge, caustic draw, slow rinse, fast rinse.
Both regeneration cycles flow opposite the service flow.
Tanks are made of fiberglass reinforced polyester.
Units use strong acid cationic and strong base anionic resins.
System uses multistage centrifugal pump of 316 stainless steel, and a touch screen control programmable logic controller.
Each system is modular and skid mounted for ease of transport and installation.
