The pH Training System is based around the pH Rig and is a self-contained educational platform for teaching pH level control and effluent treatment methods. The System comprises two independently pumped fluid circuits mounted on a robust bench-top panel which allows the study of the principles of process control using the pH of the mixed effluent and reagent fluids as the process variable. The system is suitable for individual student work or for group demonstrations. Effluent and reagent are contained in separate holding tanks prior to being pumped into the reaction tank where mixing is carried out.
