Multi-stage, Multi-force Dewatering Of Steelmaking Sludges
Abstract
A novel, sequential, multi-stage, multi-force dewatering process for steelmaking sludges is described. The process consists of stages of chemical flocculant addition, sedimentation complemented by magnetic forces, decantation of clear liquid, and finally filtration to produce a cake. The synergistic effect of the chemical, magnetic and gravity forces results in rapid and complete solid/ liquid separation. The results show that blast furnace, basic oxygen furnace, and electric arc furnace sludges can be dewatered to produce cakes containing 70 - 80 wt.% solids, while discarding clear water, which represents 75 - 90% of the original sludge volume. Thus this dewatering process has considerable potential for the treatment of steelmaking sludges to permit more efficient disposal, storage, or recycle. © 1989.
