Steel mill - Wikipedia. Often a mini mill will be constructed in an area with no other steel production, to take advantage of local markets, resources, or lower-cost labour. Mini mill plants may specialize, for example, in making coils of rod for wire-drawing use, or pipe, or in special sections for transportation and agriculture.

For example, Lastra et al. (2004) were able to separate metal complexes from pulp mill wastewater by nanofiltration. Other researchers have found nanofiltration to be effective for the removal of color and hard-to-degrade organic compounds in such effluents (Ahn et al. 1998; Huukilo et al. 2002; Mänttäri and Nyström 2007; Gönder et al. 2011; Khosravi et al. 2011; …

Rolling mills produce wastewater during the cooling of bearings and shafts. The water consumption is about 10 m 3 /ton, but by recirculation it is possible to reduce this amount of water by a factor of two to seven. Wastewater from the iron and steel industry can contain up to 5% of grease and oil when recirculation of the wastewater takes place.
