Condensate polishers have been used to keep water clean by eliminating contaminants from return condensate. The choice to refine return condensate for reuse is simply financial. Rather than utilising freshly made-up process water, the condensate may be restored to an ultra-pure condition by simple polishing. Condensate polishing is a tried-and-true technology for obtaining high grade distilled water from reclaimed boiler condensation. Condensate polishing is distinct from conventional ion exchange in that electrostatic interaction is simply a component of the whole process because the condensate is indeed of excellent quality and only needs polishing. Condensate polishing also serves to physically separate corrosion compounds from boiler condensate. A well operating condensate polisher will therefore require back cleaning and regeneration as a result of rising pressure loss as it will due to ionic depletion. The process's ion exchange includes exchanging contaminant ions for hydrogen and hydroxide ions (for the H-OH cycle) in a porosity synthetic resin environment.
