Abstract: The development of processing enterprises, their low technological level, as well as the shortcomings of the regulatory framework are the reasons for the violation of the ecological balance of natural ecosystems. Wastewater from the dairy processing industry is contaminated with easily decomposable organic substances that can cause great damage to water bodies. Existing wastewater treatment technologies are extremely energy-intensive due to the shortcomings of the analysis of the composition of liquid media, which can reveal an excess of maximum permissible concentrations of no more than ten percent of the total amount of standardized pollutants. This paper provides information on the assessment of a biotechnological solution for the intensification of wastewater treatment processes in the filtration fields of a milk processing plant, as well as an assessment of the level of their pollution. Information is presented on the results of purification and its ability to reduce the concentrations of pollutants in the filtration fields: by suspended matter by 17 times, by mass concentration of fats by 17 times, by BOD5 by 45 times, by COD by 10 times. In addition, the use of this method allows to significantly reduce the intensity of the smell, which may indirectly indicate a decrease in the release of toxic gases (ammonia, hydrogen sulfide) from the waste liquid.
