NEW HIGH-TECH COMPOSITE FLOCCULANTS-COAGULANTS AS AN ALTERNATIVE TO THE KNOWN REAGENTS FOR WATER TREATMENT
https://doi.org/10.15518/isjaee.2016.11-12.093-103
Abstract
This work relates to the technology of inorganic substances. It can be used in the preparation of aluminum-silicon and iron-silicon flocculants-coagulants. We have been proposed methods of treating wastewater of industrial enterprises, as well as storm water containing petroleum products. The article describes the specific examples of water treatment using the modified aluminum-silicon and iron-silicon flocculants-coagulants, which were obtained by the new technology. The authors have developed and patented technology for producing this type of flocculants coagulants in solid form with matrix isolation technique of active components. We have been evaluated the effectiveness of the action for coagulants-flocculants ASFC and ISFC on model and real, natural and industrial wastewaters. The article makes a comparison between the new composite materials and the known analogues.
