The characteristics and reuse of Golden Horn surface sediments

Abstract

In this study the characteristics and reuse of Golden Horn surface sediment were investigated. 40 per cent of the water content of the sediment is free and immobilised water, and the remaining 60 per cent is bound water content. In accordance with these results, the high specific resistance value of the sediment indicates its poor dewaterability characteristics. The leachate of the samples does not contain the toxic heavy metals even if the deposits get into contact with acid rain of pH 4. The sediment has strong Cu and Pb adsorption properties. Considering the metal content of the sediment, it is obvious that the sediment is not saturated with these metals. Another important characteristic of the samples IS their high buffering capacity. The reuse of the dried sediment as a clay mixture III brick manufacturing seems possible.|Keywords: Sediment, dewatering, metal adsorption
