METHOD OF WATER TREATMENT AT A THERMAL POWER PLANT Russian patent published in 2023 - IPC C02F9/00 B01D61/58 

FIELD: thermal; industrial energy.

SUBSTANCE: invention can be used for chemical water treatment for consumers. The method includes the process of preliminary water purification, water filtration by reverse osmosis, removal of dissolved gases, collection of purified water for subsequent supply to the consumer. The pre-treatment process includes coagulation and mechanical filtration of water, water heating up to 30-45°C, and then filtration sequentially in three stages: ultrafiltration, nanofiltration and reverse osmosis filtration.

EFFECT: simplification of water treatment technology by reducing the stages of water treatment by eliminating the ion exchange process for deep water desalination while increasing the productivity of water purification by eliminating additional utilization of chemical reagents and improving filtration, additional water heating and additional ultra- and nanofiltration for water purification.
