Abstract

The article represents the results of the study of the interaction of fatty acids salts as components of wastewater with calcium hydroxide in the cavitation fields which were excited in the hydrodynamic cavitator of fluid type. The potentiometry method revealed that in the cavitation fields the fullness of usage of calcium hydroxide has been much higher than at the mechanical mixing of the reaction system. The method of infrared spectrographic analysis of the products of interaction of calcium hydroxide with sodium stearate at different hydrodynamic conditions confirmed almost complete conversion of Ca (OH)2 in the cavitation fields. The article analyses the system of interconnected physical and chemical processes during the interaction of calcium hydroxide with sodium stearate in the cavitation fields, and the cause-and-effect relations between them. The role of the cumulative effect, caused by the cavitation was noted in the intensification of the interaction between these reagents. The effect of flotation of the poorly soluble calcium stearate was revealed after the treatment of the reaction system in the hydrodynamic cavitator.
