Physical and Chemical Features of Aqueous Media Treatment Process from Components of Cow Milk with a Milled Waste of Corn

Abstract

Abstract. The effluent treatment process for dairy waste water adopts physicochemical methods with adsorption playing a significant role in removing organic chemical contaminants. Corn waste, due to their abundance and large volumes, often attract the attention of environmental researchers. It is known that corn is an effective sorbent in the purification of aqueous media from oil products and dyes. In this work, there are researches of the physical and chemical characteristics of aqueous media treatment process from the components that are the part of the drainage of milk processing plants (lactic acid and asparagine) with ground thermal modified corn waste. It has been established that the obtained sorption material effectively extracts various components of sewage from milk processing plants. Extraction of asparagine occurs more efficiently than lactic acid, so for the amino acid, 91% efficiency is achieved, for lactic acid 78%. When the amount of pollutant in the range of COD values 305–320 mgO/dm3, the rational weight of the sorption material additive is 6 g/dm3.
