In the poultry industry carcasses are cooled in water. The carcasses are immersed in cold water, before being processed further. This cooling water gets turbid and contaminated with microorganisms like E. Coli and Salmonella. 

For reuse, the cooling water has to be transparent and free from bacteria. This can be achieved by means of filtration and ozone treatment. Ozone is the second most powerful sterilant in the world and its function is to destroy bacteria, viruses and odors. An American research shows that by means of ozone treatment a quality can be obtained suitable for water reuse in conformance with the American legislation. [1]
