Purifying wastewater from dairy plant

Abstract

Currently, there is a widespread expansion of existing and construction of new enterprises of the dairy industry. Sewage of dairy enterprises is characterized by a high concentration of pollution, their purification being a complex technical and scientific task. Current sewage treatment facilities do not meet the relevant standards, as a rule. This fact disrupts the municipal treatment facilities work significantly and leads to environmental pollution. Flotation and coagulation purification methods as well as their effectiveness in the application of dairy industry enterprises drains are considered. The problem of wastewater treatment of the food industry enterprises is largely related to the extraction of fats. An experimental study to determine the concentration of fat at different stages of treatment by gravimetric and IR spectrophotometric methods was conducted.
