METHOD OF ELECTROCHEMICAL TREATMENT OF WATER AND GEAR FOR ITS REALIZATION Russian patent published in 2002 - IPC

FIELD: water preparation technology, water softening. SUBSTANCE: aqueous medium is first treated in variable electric field by flow through additional non-soluble sieve electrodes and then in stationary electric field formed by key electrodes. Gear for realization of method comprises body with main non-soluble electrodes, system of D C supply, inlet and outlet pipe unions. Additional sieve electrodes are installed between inlet pipe union and key electrodes and are connected to system supplying alternating current of commercial frequency. EFFECT: prevention of deposition of hard salts on surface of key electrodes, reduced time between overhauls. 6 cl, 1 dwg
