The paper considers a way of minimizing the pollution due to ceramic sludges, by rationalizing the addition of waste waters and sludges in tile production processes. The analytical and rheological results, obtained on the body slips used for white gres tile production in waste or purified waters, demonstrate that the addition of dried sludges up to 5% wt (in place of the < 2% wt amount till now used) makes the slip completely compatible with industrial requirements.

Abstract
The paper considers a way of minimizing the pollution due to ceramic sludges, by rationalizing the addition of waste waters and sludges in tile production processes. The analytical and rheological results, obtained on the body slips used for white gres tile production in waste or purified waters, demonstrate that the addition of dried sludges up to 5% wt (in place of the < 2% wt amount till now used) makes the slip completely compatible with industrial requirements. This paper evidences the possibility of direct use of waste waters, containing sludges, in the wet grinding process, making purification treatments of waters unnecessary and greatly reducing the economical engagement.Pubblicazioni consigliate
