The use of co-polymer flocculants for the elimination of the environmental effects of wastewater of a coal washer and design of a thickener for supplies of fresh water

Abstract

A washing plant belonging to Özberil Mining Co. (Denizli/Turkey) has a 50 t/h of capacity and coal was washed with heavy media separation to increase its quality. Wastewaters of coal tailing streams of the washing plant were discharged to a river, near the washing plant. This situation has created serious problems to the river. In addition, the amount of fresh water that was needed for the washing plant is not enough. The objective of this study is to get fresh water for recirculating and separating fine solids in a state of easy handling, and coal tailing streams of the washing plant are eliminated of environmental effects. Therefore, laboratory flocculation experiments were carried out with the aim of designing the wastewater treatment facility for establishing optimum sedimentation conditions in this plant. After the laboratory tests, engineering design was completed for the wastewater treatment plant. Thus, in the result of this study was found a suitable solution for the wastewater for the Özberil coal washing plant. © 2013 Copyright Taylor and Francis Group, LLC.
