Domestic and industrial (especially ore beneficiation) processes produce large volumes of wastewater contaminated with fine particles. The most common method used in dewatering is the conditioning and precipitation of pollutants with special chemical agents. The equipment commonly used for this purpose in mining industry is called thickener. The aim of this study is to examine the effect of static electricity on the sedimentation behavior, in addition to the methods used for dewatering industrial wastes. In this context, the flocculation and coagulation behavior of the sludge obtained from a blast furnace used in the iron and steel industry was investigated. Following the determination of the optimum flocculant and coagulant dosage, precipitation tests were performed using natural (without chemicals) and triboelectric implementation. Two commonly used methods (Talmage-Fitch and Coe-Clevenger) were used and compared for the determination of settling rates. Results of this preliminary study under certain conditions showed that triboelectricity yields higher rate of precipitation results compared to tests performed without chemicals and with the use of coagulants. However, they are quite low compared to the settling times obtained with the use of flocculants.
