<p>Water is passed through a vessel where a flow of absorber material removes dissolved minerals. A regeneration phase is inserted between two absorbent phases, using a salt solution which further removes minerals. The water being processed is passed through an additional desalination stage (20), and at least part of the extracted salt is used during the regeneration phase on the absorbent material. The desalination stage is after demineralizing and water softening action. During the water processing, it is passed through a water softening resin. The desalination uses a reverse osmosis action. During the regeneration phase, an additional store volume of salt solution can be connected, with the salt solution prepared close to the supply vessel (26). A reverse flow is passed through the vessels (1,2) against the main water processing flow direction, during the regeneration phase. At least two vessels (1,2) are linked to the desalination stage (20), with reversing processing and regeneration phases. The switch between the processing phase and a regeneration phase is effected according to the level of mineral substances absorbed by the absorbent material, measured by electrical conductivity. An independent claim is included for a water processing assembly, with an additional desalination stage (20) linked to the water processing vessels (1,2). The outflow (22) of concentrate from the desalination stage (20) is returned under control to at least one vessel (1,2). Preferred Features: The desalination stage (20) is a membrane concentrator, with at least one membrane for a reverse osmosis action. The flows through the vessels (1,2) are controlled by a number of valves (6-9,15-18). The vessels (1,2) contain at least one absorbent resin as the absorbing material. A back rinsing connection (23) at the vessels (1,2) is linked to the desalination stage (20) and also with the supply vessel (26) with additional prepared salt solution.</p> |
