INDUSTRIAL WASTEWATER

Abstract

Waste is any material or object that occurs during the performance of manufacturing, service or other activities. Items excluded from use, and waste materials generated in consumption and that, in terms of producers or consumers are not for further use and must be discarded. The research for this paper has two parts. The first part was to assess the amount of generated municipal waste, so that in the period of fourteen days was measured the quantity of municipal waste before selection, processing and landfilling. This includes also the test was sampling and analyzing morphological composition of waste in the city of Leskovac, in accordance with the European Waste Catalogue which is used for the classification of all wastes and for sorting waste, too. In the second part, solid waste on the basis of cellulose is used for the production of activated carbon, which is then used for the reduction of textile dyes coloration in the wastewater. Based on the results, it can be said that the activated carbon produced from waste paper has potential as an adsorbent for the removal of textile dyes from aqueous solutions after dyeing process. Prolonged contact time means a greater amount of dye on the adsorbent, i.e. the dye concentration in the solution decreases with the duration of the adsorption, and the actual amount of adsorbed dye increases with the increase of dye concentration.
