METHOD OF WATER TREATMENT

摘要

FIELD: process engineering.SUBSTANCE: invention relates to water treatment for reduction the content of salts and suspended substances. Proposed method comprises filling the tank with water to effect acoustic cavitation to level of 0.15-0.5 in evacuating the tank to 0.3-0.9 kgf/cmaccompanied by filtration. Cavitation is caused by simultaneous action of ultrasound different-frequency opposed oscillators. Low-frequency oscillator excites broad spectrum of frequencies while high-frequency oscillator excites one oscillation frequency ten times higher than that of low-frequency oscillator main frequency. In compliance with preferable version, main oscillation frequency excited by low-frequency oscillator makes 1.8 kHz while that caused by high-frequency source makes 18 kHz.EFFECT: intensified treatment, deep cleaning.4 cl, 1 dwg, 1 ex
