The article presents results of mathematical modeling of physical and of chemical processes hydrothermodynamic processing of industrial waste water on the basis of of effects supercavitation. To optimize the parameters of hydrothermodynamic cavitation as the basis nonchemical treatment of industrial waste, is used a model with the parameterization of indicators arising at this energy, its conversion, as well as changing the properties of the liquid and modiёcation of admixtures. Is represented model dependence between the parameters (modes) cavitation and efёciency of industrial wastewater treatment.
