Abstract
The empirical analysis of the scheme of whey treatment was carried out. Controlled parameters for the further investigations and assessment criteria of effectiveness of whey treatment have been singled out: the best conditions for protein coagulation, intensity of flocculation, the choice of the facility capable of effective working with high temperature of waste water and flocculant application contributing to formation of the larger flakes and process intensity. Real-time experiment on dairy enterprise LLC “SCHUCHINSKY CHEESE MANUFACTURE” was carried out. The following equipment was applied in the experiment: electroflotator, screw dehydrator, pump assemblies, containers for preparation of reagents and whey heating, measuring equipment: pH-meter, flowmeter, thermometer, photometric analyzer of chemical oxygen consumption (COC), scales. In the process of the experiment on the plants we determined the data of COC, pH and mass of emitting protein depending on the type of the flocculants used: superfloc A-130 and praestol 2530. The results of the experiment with whey treatment with COC equal to more than 10000 mg/l revealed high effectiveness of high charge anionic flocculants. New innovative technology of separate whey treatment in the technological process of dairy factories without its discharge to waste water is presented.
