The removal extents of dyes over s-Fe 0, nZVI and iron power were similar, which were significantly higher than those over iron scurf. However, the cost of s-Fe 0 is only ∼1% of nZVI. Thus, the degradation process of dyes over s-Fe 0 exhibits several advantages, including higher degradation rate, and lower cost.

Energy consumption and production capacity are two major concerns in the steel making industries which are using electric arc furnace (EAF). To improve the performance of EAF, a new initiative technique has been introduced in which sponge iron particles are preheated before entering the furnace. A heat exchanger is used to transfer waste energy from EAF flue …
