Marlo Packaged Batch DI Regeneration Plants support the providers of a portable exchange deionization (PEDI) service business with an operator-friendly, pre-engineered design to regenerate exhausted mixed-bed resin at their facility. The standard system includes a resin separation vessel which allows for the transfer of the cation and anion resin into separate vessels to be regenerated simultaneously. After regeneration and rinse to quality, the cation and anion resins are sent to a final vessel to remix before being placed back into the exchange tanks and returned to service.
