Use of Ion Exchange Filters in Wastewater Treatment

Abstract

The authors describe the existing methods of electroplating wastewater treatment in industrial enterprises of the world, particularly in the engineering industry. In this paper, the authors address issues of modernization of the existing system of electroplating wastewater after treatment by the example of the machine-building enterprises through ion-exchange filters. The calculations are carried out on the example of applying cat ion and anion exchange filters. These filters allow one to change the ionic composition of the solution and to carry out its complete demineralization. They have a relatively high filtration rates, the possibility of fully automate systems and the possibility of regenerating ion exchangers, though impurities removed from water do not form a precipitate. The research has shown that the solution of merely technical challenges results in overloading and reducing the efficiency of wastewater treatment plants. Sustainable development could be achieved through the reorientating industrial processes of goods producing and services onto the new models, implementing environmentally friendly technologies for the creation of environmentally friendly production, ensuring a more efficient use of raw materials, replacing the most toxic electrolytes, systematic and irregular changing technological solutions and developing ways to recover waste solutions containing the same type of components.
