Purification of industrial and waste water using matrix-isolated nanocomposite flocculant-coagulants

The paper presents the results of studies on the industrial purification of oil-containing wastewater with the use of new nanocomposite flocculants-coagulants ASFC and ISFC. They were tested using the methods of wastewater treatment industries, as well as rain water containing oil. Specific examples of water purification were examined, using new aluminum-silicon and iron-silicon flocculants-coagulants. The authors have developed and patented the technology of obtaining flocculants-coagulants of this type in solid form. To produce such composite materials, the method of matrix isolation of active components was used. An efficiency of coagulants-flocculant ASFC and ISFC used in real industrial wastewater has been evaluated. Comparison was made for new composite materials with known analogues.
