Analytical Process Control System

Analytical Process Control System

Product Details

Technical Description
The RT 586 Analytical Process Control System demonstrates the control of the quality of industrial process water and waste water. It combines chemical procedures with applied basic principles of control engineering.
The mobile laboratory unit is dimensioned in a way to allow experiments, without neglecting the characteristics of industrial plants. Neutral water is mixed with diluted sodium hydroxide, the resulting ion load is measured. The addition of diluted sulphuric acid neutralises the solution. Controlled aeration changes the oxygen content. Another experiment controls the redox potential of water using a diluted iodine solution. All processes are equipped with extensive instrumentation and are controlled by industrial controllers. Transparent reaction tanks enable the processes to be observed.

Learning Objectives / Experiments
· Simulation of a salt load in water by addition of diluted sodium hydroxide via a conductivity control system
· pH-value control of the solution using diluted sulphuric acid
· Change in the oxygen content by means of controlled aeration with compressed air
· Control of the redox potential via addition of diluted iodine solution
