Utilization of Sludge of Water Supply Treatment Facilities

Summary

A possibility of the use of sludge of potable water supply treatment facilities for production of pottery is investigated. Technological tests show that the use of sludge of the Khabarovsk’s treatment facilities as additives to common clays in a dose up to 15% of raw material weight makes it possible to solve a problem of their utilization without a decrease in quality of a produced product. The possibility of the use of treatment facilities sludge in a dose from 3 to 15% as alloy additives making it possible to improve plasticity of ceramic mass, to improve conditions of its sintering, to reduce parameters of shrinkage at all technological stages of preparation of raw materials and manufacturing of products, to reduce the size of pores generated and to improve indices of water-absorbing ability is established.
