METHOD OF WATER DISINFECTION AND ASSESSMENT OF ITS EFFICIENCY Russian patent published in 2014 - IPC C02F1/50 C02F1/30 C09B47/04 

FIELD: chemistry.

SUBSTANCE: invention relates to the field of biotechnology. Claimed is a method of water disinfection and assessment of its efficiency with respect to an indicator, potentially pathogenic and pathogenic bacteria. The method includes application of water-insoluble heterogeneous sensitisers based on phthalocyanines, inoculated to aminopropyl silica gel. The sensitisers with a positive electric charge, containing in the structure of their active phase aluminium, zinc or silicon phthalocyanines, with a concentration of an active phase 5 mcM/g, are applied. The sensitiser in a concentration of 4-5 g/dm³ is introduced into infected water with its further keeping in darkness with the following illumination with active bubbling of air oxygen. After that, after the sensitiser precipitation water is sampled from the supernatant fluid. Inoculations of disinfected water volume are carried out. A number of grown colonies is calculated. Efficiency of the disinfecting action of the sensitiser is calculated and is evaluated as high if a value is ≥99.99%, medium if the value is from 80.9 to 99.98%, low if the value is <80.9%.

EFFECT: invention makes it possible to extend the arsenal of the applied water-insoluble heterogeneous sensitisers for water disinfection.
