Control System for Chromium Recycling Technology

The leather industry uses a by wastes of meat industry, and, as such, significantly reduces the environmental impact. It is therefore evident that term „waste“ is relative. It can be argued that if the "waste" generated in one industry sector can successful be utilised as a raw material in another industry sector for the manufacture of goods, we need to rethink our philosophy on the use of resources. This paper describes a proposed comprehensive computer control and monitoring system for a recycling technological process of both liquid and solid wastes from the tanning industry. The chromium tannery wastes are potential dangerous for the environment. As an experimental laboratory model were built in the Department of Automatic Control Faculty of Technology Tomas Bata University in Zlín an apparatus fully equipped with sensors and actuators.
