Application of alternating magnetic field in wastewater treatment at yeast enterprises
The work is devoted to solving the current scientific and practical problem of increasing the level of environmental safety of yeast production through the use of an alternating magnetic field (AMF) for wastewater treatment and disinfection. The list of industrial effluents' main treatment methods from organic, mineral, and biological pollution is determined. The advantages and disadvantages of these cleaning methods are established. The application of physicochemical technologies of wastewater treatment of yeast production in Ukraine and abroad is considered in detail; the characteristics of their application's physicochemical methods, industry, and conditions are determined. The prospects of using an AMF as a method of purification and disinfection of yeast production wastewater are noted. The physicochemical and microbiological composition of wastewater was studied with the help of physicochemical and microbiological analysis. After exposure to a magnetic field with a magnetic induction intensity of 75 mTl for 10 minutes, there was a decrease in the physicochemical index of chemical oxygen demand by 72 %. The degree of purification by other indicators is in the range of 30 – 50 %, and the degree of disinfection of microorganisms is 87 %. Further development of knowledge on the influence of AMF on the process of wastewater treatment of yeast production depending on its parameters and duration of action. The results of the study can be used to select treatment equipment at yeast plants.
