SEAWATER DESALINATION PLANT Russian patent published in 2022 - IPC C02F1/469 C02F103/08 

FIELD: water purification.

SUBSTANCE: invention relates to the desalination of salty sea and lake waters, as well as the production of concentrated solutions of various substances. The seawater desalination plant contains a chamber with two parallel diaphragms installed along and symmetrically relative to the walls of the chamber for cleaning from dissolved salts, dividing the chamber into two zones, as well as two electrodes of different polarity. The reverse osmotic membrane is located inside the second zone of the chamber bounded by two diaphragms, which is connected to a variable capacity pump for pumping permeate. The first zone of the chamber is divided into two halves united by a branch pipe: right and left relative to the direction of the seawater flow. The two outputs of the positive and negative poles of the control unit are connected to the first and second electrodes located on the outside of the chamber to the two halves of the first zone, respectively. The output of the control unit is connected to a variable capacity pump for pumping permeate, and the first and second inputs are connected, respectively, to a permeate conductivity sensor and a concentrate pH meter. The output of the first zone is the output of the concentrate.

EFFECT: efficiency and duration of operation of the device is ensured.
