Abstract:

An on-line operational support system with an underlying dynamic mechanistic model was developed for simulating water inventories at an industrial water treatment plant. Customized unit process models for hydraulics in variable volume tank, overflow tank, sand-filter (SF), activated carbon (AC), ion-exchange (IE) and reverse osmosis (RO) were developed in the GPS-X simulation environment. The control system used at the plant was replicated using different control models of on/off feedback control, sequencer control and/or logical combination of two or more feedback control conditions. The whole treatment plant model was built using individual unit processes complete with all physical, operational and control information. The support system was equipped with a data pre-processor which processed on-line data to generate appropriate model initial conditions. A customized front-end graphical user interface was provided for displaying historical and simulation data along with warning signals. The simulation system was validated using operational plant data and important sources of error were identified. Correctional strategies for overcoming and mitigating these errors were tested. The preliminary results were encouraging and confirmed the feasibility of the dynamic modeling approach. The simulation system is also envisioned to be of potential value in optimization of storage tank volumes, pump capacities and control system testing during plant design using suitable optimization functions.
