Abstract
Dairy wastewater consists of transport water and raw materials washing, technology water, condensation water or cooling water from the washing and disinfecting rooms, manufacturing and packaging equipment cleaning and water from plumbing. These wastewaters are characterized by a high turnover of physico-chemical and microbiological properties due to their composition and origin variety. Because of the composition of protein, fat, and lactose, wastewater cannot be discharged to the sewerage system before their purification, because the mere disposal would pollute the environment. The main purpose of this research is to monitorize the quality of water in the milk processors industry, in order to ensure food security by framing it within the limits permitted by current rules.
