WATER PURIFICATION BY COAGULATION UNDER THE INFLUENCE OF ULTRASONIC FIELD

Blog Article

The authors carried out experiments on the in-fluence of ultrasound on the subsidence of suspended materials.The efficiency of coagulation process in wa-ter purification in ultrasound field is estimated.The influence of ultrasound on the water with suspended materials before introducing coagulant was a condition of the experiment.

The magnetostriction method for obtaining ultrasound oscillations with the help of ultra-sound generator of batch production was applied.The samples were patrol belt chosen and the coagulation process was controlled using standard procedures.The experimental data was obtained which estimate the efficiency in-crease in the subsidence of suspended materials de-pending on the duration of ultrasound processing.

Dur-ing one minute of ultrasound processing the following results were obtained: the subsidence efficiency in-creased by 25.83 % in case of coagulant share Al2O3 Hydrating Cleanser 2.5 mg/l; the subsidence efficiency increased by 23.

70 % in case of coagulant share Al2O3 5.0 mg/l.
