Determination of the technological parameters for the sonochemical purification of oily water

Ultrasound allows for the significant intensification of modern technologies, providing for the reduction of their energy capacity and the improvement of the quality of the final product. An experimentally revealed essential increase in the activity of crystals obtained in a galvanocoagulator upon ultrasonic exposure allowed for the elaboration of a new technology for the purification of large amounts of polluted waters in special reaction vessels. At the Institute of General and Inorganic Chemistry of Russian Academy of Sciences, a method for the purification of wastewaters from oil products and heavy metals using a galvanocoagulant as a reagent was developed. To realize this technique, flow drum reactors (galvanocoagulators) operating in a continuous mode by microferritization using magnetite, which is obtained by the electrochemical method directly in the rolling drums, are used.
