Application of Mill Scale Waste for Geoecological Protection of Aquatic Medium

Abstract

The potential for use of mill scale (metallurgical production waste) as an affordable sorption-filtration material for aqueous medium protection from phosphates and heavy metals is considered. The results of X-ray phase studies of mill scale prototypes, as well as extraction of dissolved components from them into bidistilled water at long-term contact, which revealed insignificant emission of harmful substances indicating safety of the mill scale application as a sorbent, are given. It is proposed to use industrial cartridges (filter cartridges) loaded from rolled scale to purify large volumes of surface wastewater in real conditions.
