UTILIZATION OF SLUDGE RESULTED FROM CHLORINE INDUSTRY IN WASTWATER TREATMENT (Enviromental Chemistry Study)

Abstract

Over the last periods of times, the contamination of water resources by the heavy metal ions has steadily been increased as a result of over population and expansion of industrial activities. Because the toxicity of heavy metals and their serious threat to the human health and ecological systems, an intensive care and research efforts are continuing to find and develop cheaper treatment technologies which are appropriate to a variety of industrial simulations. Currently, the adsorption technique is believed to be a simple and very effective technique for the treatment of water and wastewater where success of the technique is depending largely on the efficient of adsorbents and thier development. In our study two different types of solid waste materials namely; burnt brine sludge (BBS) and non burnt brine sludge (NBBS) as cheaper and very low cost adsorbents were used for the removals of the heavy metal ions Pb+2, Cd+2 and Cu+2 from their aqueous solutions. The heavy metal salts used in this study were; Cu(NO3)2•3H2O (MW: 241.6, purity: 99% and produced by Central Drug House (p) LTD laboratory reagent), Cd(NO3)2•4H2O (MW: 308.48 and purity: 99% and produced by Central Drug House (p) LTD laboratory reagent) and Pb(NO3)2•6H2O (MW: 331.21 and purity: 99% and produced by Alpha Chemika laboratory reagent). The burnt brine Sludge (BBS) and non burnt
