SOLUTION FOR CLEANING WATER BODIES FROM CYANOBACTERIA AND GREEN ALGAE Russian patent published in 2021 - IPC C02F1/24 C02F1/50 C02F1/72 C02F1/28 C02F9/04 C02F9/14 C02F103/04 

FIELD: disinfection.

SUBSTANCE: invention relates to disinfection and cleaning water bodies from cyanobacteria and green algae. The solution for cleaning water bodies from cyanobacteria and green algae includes sodium percarbonate powder and a binding agent - a water repellent. As a binding agent, it contains a hydrophobizator melt in the form of a refractory triglyceride fraction to ensure the formation of a superhydrophobic coating on its basis with a contact angle of 155-165. The solution for cleaning water bodies is obtained by adding a hydrophobizator melt to sodium percarbonate powder heated to a temperature of 60-70C at a ratio: sodium percarbonate - 85-97 wt%, hydrophobizator melt in the form of a refractory triglyceride fraction - the rest. One should mix the components smoothly and keep the mixture at a temperature of 65C for no more than 5 minutes. After that one should cool it to room temperature and the resulting mixture is ground to a dispersed state with a particle size of 50-250 mcm.

EFFECT: invention provides synergistic effect when cleaning vast reservoirs, reducing the cost and expanding the range of compositions for water purification from cyanobacteria and green algae.
