PROCESS OF WATER TREATMENT Russian patent published in 2003 - IPC

FIELD: ecological treatment of water. SUBSTANCE: invention can find use in processes of softening, clarification, decolorizing and deironing of water in chemical, food, pharmaceutical industries, in production of oil and gas, in public utilities. Process includes pH correction by way of multiple successive increase and decrease of pressure of water. Water is heated with increase of pressure to temperature nearing boiling point, not allowing it to boil, is kept at this temperature in the course of 5-10 min and is cooled with decrease of pressure. Proposed approach ensures reduction of pH of water to value below 7.0 without use of any chemical reagents. EFFECT: raised potential of process. 1 dwg
