METHOD AND DEVICE FOR TREATMENT OF AQUEOUS SOLUTIONS Russian patent published in 2019 - IPC B08B3/10 

FIELD: chemistry.

SUBSTANCE: invention relates to equipment related to physical and chemical methods of treatment of aqueous solutions. Primary area of use is purification of industrial and domestic effluents, household and drinking water for heat supply. Process equipment is flushed with washing solution with low or high pH. To prepare flushing solution, electrochemical reactor is connected to process equipment. Interelectrode space of the reactor is partially filled with granules of anionite and/or cationite. Reactor electrodes are connected to positive and negative poles of constant voltage source and water with neutral pH is passed at electric field intensity in interelectrode space 1 * 10² - 3 * 10³ V/m. To restore initial state of ion-exchange resins, electrodes are disconnected from voltage source and water with neutral pH is passed through electrochemical reactor chamber.

EFFECT: technical result: fast and efficient cleaning, environmental safety.
