A new synthetic polymers used in removal of pollutants from industrial effluents

Chemical products synthesised using polymer waste have a great significance in industry. Chemical modifications of this type of waste make it possible to obtain products having new properties and at the same time to decrease the amount of usually dangerous waste in the environment. The products can be used in the processes reducing environmental micro-pollutants and in particular in wastewater treatment processes. There are more and more possibilities to use new synthetic polymers in industrial effluents treatment due to dynamic development of the technology of water and sewage treatment. Besides, technological changes of production processes make it necessary to carry out research on new polymers used in the processes of industrial effluents treatment. Despite the fact that in wastewater treatment technologies small amounts of organic polyelectrolytes are used, their global consumption is still quite big. A new generation of chemical products: flocculants synthesised from polymer waste ware used in coal mine pit waters treatment with good results. In the chemical modification of polystyrene waste as well as of post-production waste of phenol-formaldehyde resins, the products of specific flocculation properties and reducing the indicators of macro and micro-pollutants in industrial effluents were obtained. The products appeared to be effective flocculants supporting the coagulation process of coal mine pit waters.
