  • Purification of wastewaters using matrix-isolated nanocomposite flocculant-coagulants

    This work relates to the technology of inorganic substances. It can be used in the production of aluminum-silicon and iron-silicon flocculants-coagulants. With their help, methods for treating wastewater from industrial enterprises, as well as storm water containing oil products. In this paper, concrete examples of the research results on the purification of natural, industrial and oily wastewater. With the use of new nanocomposite silica-alumina and iron-silicon flocculants-coagulants ASFC and ISFC, obtained by the new technology. The authors have developed and patented the technology of obtaining flocculants-coagulants of this type in solid form. Method of matrix isolation of active components has been used to prepare such composite materials. Performance evaluation was given to the action of coagulants, flocculants and ASFC ISFC. A comparison was made with the new composite materials commonly used for these purposes the conventional art, coagulants - aluminum sulphate and iron sulphate. With their help, the methods of treating wastewater from industrial enterprises, as well as storm water containing oil products. An assessment was made of the effectiveness of the action of coagulant flocculants ASFC and ISFC on real industrial wastewater.
