High Purity

2-Bed Demineralisation Systems functions

The MIX-2BD series are complete packaged 2-bed demineraliser systems that incorporate proven counter-current configuration in a packed resin bed.

In the MIX-2BD, feed water enters the packed bed upward in the service cycle and downwards in the regeneration cycles. In the upward service cycle, the resin bed is lifted up in a compacted state. As the water progressively comes into contact with the more regenerated resin, high quality water production is ensured with lower ionic leakage.

The MIX-2BD is packed with narrow bead size resin which provides excellent fluid hydraulics, has lower susceptibility to fouling and minimizes channeling during regeneration. The resultant improved resin kinetics also means less mechanical and hydraulic damage to the resin beads during service and regeneration.

Macroporous resin can also be supplied as option where required.

The effluent from the MIX-2BD is largely neutral due to the equivalence of cations to anions. As acid and caustic are both introduced into the packed bed at the same time during regeneration, the effluent generated is mostly neutral.

The MIX-2BD systems compact design comes fully mounted on a skid with a corrosion resistant frame. A stainless steel multistage pump is included to provide sufficient pressure & flow during service and regeneration.
