Improvement of environmental sustainability of milk processing enterprises

Abstract

Sewage from milk processing enterprises remains a factor of environmental pollution. This is caused by a high concentration of organic pollutants contained in a dispersed and dissolved state, among which protein predominates. An effective way to increase the environmental friendliness of dairy enterprises is to minimize emissions of pollutants. In particular, this applies to dairies, the main products of which are protein products - cheese and casein, and the main pollutant - whey. This could be achieved through complete processing of whey. The article considers the possibility of reducing the polluting effect of wastewater from milk processing enterprises by separating dispersed protein from milk whey. The results of the study of the content and granulometric composition of dispersed whey protein are presented. The design of the filter with a self-cleaning filter element developed by the authors is presented, which allows for a continuous process of serum purification with a consistently high degree of separation.
