METHOD FOR WATER PREPARATION FOR FOOD PRODUCTIONS Russian patent published in 2014 - IPC C02F9/12 C02F1/32 C02F1/36 B01J19/08 C02F103/04 

FIELD: food industry.

SUBSTANCE: method involves water purification from mechanical admixtures by way of filtration, water treatment with pulse ultrasound field with a frequency equal to 22±1.65 kHz, ultrasonic oscillation power equal to nearly 120-200 W, intensity equal to nearly 10-20 W/cm² and exposure lasting 3-5 minutes. Then water is repeatedly filtered and treated with ultraviolet radiation at wave length amounting to 200-250 nm.

EFFECT: drinking water treatment technology simplification combined with simultaneous increase of the degree of water purification from undesirable admixtures and the required quality water obtainment.
