Abstract

The new plant operates as a compact bed and comprises two U-shaped columns; one column has an active section, where the treatment is effected, and a transfer section of smaller dia. There is also a regeneration column, with an active section in which the resin is regenerated, and a transfer section of a smaller dia. The resin circulates in the active portion under the action of an impeller; its flow is automatically adapted to the quality of the water to be treated and waste of the regenerating reagent is avoided. The installation is used in the first stage of demineralisation to eliminate the cations, coming from the dissolved salts, from the water. The cations may be Ca++ ions and are exchanged with H+ ions by the strong acid cationic exchange resin.
