TECHNOLOGY OF VAPOR CONDENSATE PURIFICATION OF MEAT AND BONE MEAL PRODUCTION
The purpose of the conducted researches was the development of ecologically safe and efficient technology of purification of vapor condensate (VC) generating during evaporation and drying of raw material at the meat and bone meal production. For the VC purification a method of biochemical oxidation in anaerobic and aerobic conditions and a method of ultrafiltration were used. The researches were conducted on the laboratory automated installation. It was proved that the VC purification was more efficient by applying the biochemical method. The method of ultrafiltration failed to produce required results. Based on the findings, a technology of VC purification by means of a biochemical method including biological elimination of nitrogen and reagent elimination of residual phosphorus is offered.
