Control recycling technology of tannery chromium wastes

Abstract

The leader industry produces several kinds of wastes. That is why is necessary to look for the technologies and methods to process these waste to the products unloading the living environment. The solving of the recycling technology for the liquid and solid chromium wastes is only one problem from this area. The importance exactly of this problem results from the fact, that the chromium tannery wastes are potential dangerous for the environment. In this contribution there is described mathematical model of the recycling process, proposal of the laboratory technological equipment for the total chromium recycling of the liquid and solid waste. For this laboratory equipment was solved the computer control system with the full control algorithm closed recycling technology according to optimal electrical energy and alkali solution consumption. Experimental laboratory model were built in the Department of Automatic Control Faculty of Applied Informatics Tomas Bata University in Zlin an apparatus fully equipped with sensors and actuators.
