METHODS AND SYSTEMS FOR OBTAINING A HIGH CONCENTRATION OF DISSOLVED OZONE IN LIQUID MEDIA Russian patent published in 2021 - IPC C02F1/78 B01F3/04 B01F3/20 A61L2/18 B01F5/02 B01F5/10 C02F1/66 

FIELD: treatment of water.

SUBSTANCE: invention can be used in purification of water in the chemical and pharmaceutical industries. The method for continuous production of ozonised water includes injecting an acidifying agent into a jet of supplied pressurised water to maintain a pH below 7 and supplying pressurised water into a dissolution column to form acidic pressurised water. A two-phase mixture of gaseous oxygen and ozone and recirculating water is sprayed into the acidic pressurised water in the dissolution column, producing ozonised water therein. The pressure of the dissolution column is maintained in the range from 2 to 7 bar g. by controlled release of a jet of exhaust gas from the dissolution column. The ozonised water is released from the dissolution column and the flow rate thereof is adjusted so as to correspond to the flow rate of the pressurised water jet supplied to the dissolution column after injecting the acidifying agent. Proposed are methods and systems for continuous production of a gas-free liquid containing dissolved ozone and a gas-free oxidiser for liquid oxidation processes, as well as a system for continuous production of ozonised water.

EFFECT: inventions provide a possibility of reducing the ozone losses and increasing the concentration thereof during dissolution.
