Who wouldn’t enjoy a large, cold ice cream in a hot summer day? However, production of ice cream can be challenging for the municipal waste water treatment plant that receives sewage from the dairy. Large amounts of fat and high organic load can harm the treatment process, and therefore, sewage from the dairy can be accepted only in moderate doses. Quite cheap and simple solutions can significantly improve the situation; a balancing tank and a good cooperation together ensure efficient treatment! See from the video how a Finnish dairy has solved the problem in cooperation with the local waste water treatment plant.
