Abstract
The development of mathematical models for the dynamic simulation of the pretreatment section in Reverse Osmosis plants, used for drinking water production, is presented. The objective is to use these models to reduce energy consumption and exploitation costs by testing and comparing advanced control strategies. Thus, these models have been developed for implementation using off-the-shelf software (EcoSimPro), so that advanced control algorithms can be easily tested, while the parameters are selected to be simple to obtain from available plant measurements, so the models can be easily adapted to specific plants.
