Liquid Organic Waste Purification on the Example of Beet-Sugar Production Using Cavitation Hydrodynamic Generators

The authors presented a mechanism for optimizing the results of studies of an integrated system for treating waste beet sugar production using cavitation hydrodynamic generators, a chemical treatment, and an ozonation system. As a result of the research, the synergy effect was confirmed when using the cavitator in conjunction with other methods of exposure. Also, the authors established the optimal modes for the selected types of exposure and processing environment. The scale of the problem is shown - more than 2 trillion tons of world beet sugar production waste and the alternative possibilities of using this cleaning system are described. The main problem of cleaning these wastes is the presence of saponin in them, which is a natural toxic substance that can cause hemolysis of red blood cells and is a depressing factor for the development of aquatic organisms when these wastes enter their environment. The emphasis of cleaning is shifted towards the maximum removal of saponins from the solution. Based on the purification performed and the use of control measurements by determining light absorption coefficients (transparency), a purification result was obtained that meets basic requirements, including European standards for wastewater treatment quality. The possibility of applying this technique to expand the number of optimization factors is shown.
