Demineralization plants remove all cations and anions from water. The Demineralization system consists of an acid/alkali resistant pressure vessel with internal combustion and initial switching of cation and anion exchangers. A range of regenerators, hydraulics, ejectors, acid and alkali tanks, and conductivity meters provide the pure, completely dissolved salt-free water required for energy projects, the pharmaceutical sector, battery water, the electronics industry, and textile/process water applications provide good water.
