Abstract :
The author explains how an adaptive pH controller deals with multiple reagents in a comparatively simple fashion. The titration curve is divided into separate reagent and waste stream models, allowing `plug-in´ reagent changes. The controller can perform online identification of a single waste stream model, combining data gathered with any number of different reagents. The controller runs in a standard Bailey NETWORK 90 DCS, and has been pilot-plant-tested with good results
