Use of Water Treatment Sludge in the Production of Building and Ceramic Materials

Abstract

The technological process of natural water treatment before being supplied to the water supply network is accompanied by the formation of water treatment sludge. The chemical composition of water treatment precipitation is characterized by the presence of aluminum and iron hydroxides, manganese oxide, and an undissolved residue of chemical reagents used in water treatment. The strategy of sustainable development presupposes proper management of man-made waste, capable of ensuring their reuse and reducing the associated environmental burden on the environment. There are known options for using water treatment sludge in the production of bricks, expanded clay, and cement. The use of water treatment sediments in the production of burnt ceramic materials is effective. A promising direction for the utilization of water treatment sludge is the possibility of its use in a mixture with peat as a potential raw material for the production of construction and ceramic materials. An installation is developed for the collection of milled peat, its mixing with water treatment sludge, and subsequent drying of the resultant mixture.
