The target of this diploma thesis is to create a proposal in concrete production establishment for transfer and filtrate of the industrial waste water by production of aluminium parts with high preasure die casting technology. This thesis contain short overview about the high preasure die casting technology. Knowladge about high preasure casting maschine and about the casting cell with focus on his liquids that are used during production with target to identified the sorces of water contamination. There is mentioned an actual state of the abstraction and clearing waste water in the selected establishment and is presented technology for clearing of industrial waste water in this paper. In the practic part there are recovered and realized measurements of pH and chemical consumption of oxygen on the basic of which recommendations for optimalization of clearing of industrial waste water were established.
