Iron (Fe) used to produce coagulants and flocculants, can come from various sources such as: pickling liquor. mill scale or scrap from the steel industry. copperas or ferrous sulphate, from the titanium dioxide production. LKAB Minerals’ MagnaChem is a high grade, natural alternative iron source to these recycled and less pure products.

coagulation–flocculation for the treatment of industrial waste-water treatment, aiming at performance optimization, i.e. selection of the most appropriate coagulant, determination of experimental conditions, and assessment of pH effect and investigation of flocculants addition Holt et al., (2002).

Coagulants. Coagulants can enhance the efficiency of flocculants used for solids removal in wastewater clarification. Coagulants neutralize surface charges, thus increasing the performance of the flocculant. Nalco flocculants can aid sedimentation in water clarification. These polymers could be used with a coagulant for charge neutralization.
