Mechanical treatment of waste water from fat substances in the ultrasonic field
Moscow State University of Civil Engineering, Yaroslavskoe shosse, 26, Moscow, 129337, Russia
The use of ultrasonic vibrations in the technology of waste water purification from fat substances is part of the scientific problem of using in this area of knowledge of physical methods, which include: ultrasonic, magnetic, high-frequency, roentgen, ultraviolet and other. Currently, ultrasonic vibrations are widely used in various industries: metallurgy, chemical, mechanical engineering, medicine and other. The wide use of ultrasound is explained by the variety of phenomena occurring in the ultrasonic field. Ultrasonic vibrations initiate dispersion and emulsification of substances, contribute to coagulation and degassing, affect the processes of crystallization and dissolution; it is known that ultrasound causes a variety of chemical transformations of the substance, including oxidation, reduction, polymerization and so on. The explanation of these phenomena is found in a variety of ultrasonic effects: cavitation, shock waves, micro-flows, acoustic wind and so on. The schemes of ultrasonic generators are continuously improved, works on the development of methods of using ultrasound and on the search for new areas of its application are progressing. Under these conditions, the question of the possibility of using ultrasound for the treatment of waste water from fat is relevant. However, the theoretical side of this issue is a little-studied object.
