METHOD OF CLEAVING ORGANICS IN WATER Russian patent published in 2005 - IPC

FIELD: water treatment.

SUBSTANCE: invention relates to cleavage of organics in water containing more than 2 ppm toxic organics along with carbonic acid or carbonates performed by treating water with ozone and to generation of chlorine by electrolysis of sodium chloride using aqueous sodium chloride solution obtained during ozonation of water containing more than 2 ppm toxic organics and 2 to 20% sodium chloride along with dissolved carbonic acid or carbonates. Ozonation is carried out at 10 to 130^оС and gauge pressure from 0.5 to 3 bar over a period of time from 1 min to 10 h, pH of supplied water being within a range of 2 to 11. Such procedure lowers content of organics in water containing at least 0.1% carbonic acid or carbonates, while concentration of toxic organics falls below 1 ppm.

EFFECT: increased process efficiency and avoided use conventional chemicals, excessive pH, and UV emission.
