In this paper we propose a discrete model that can be used to predict the fouling status of a membrane during multiple production- and cleaning cycles. The proposed model is used to minimize the overall operating costs - based on chemicals and energy consumption - over a fixed time horizon, guaranteeing production of a specified volume, where the number of cycles, the production flow, the duration of a production step and the duration of a subsequent cleaning step is computed. The membrane fouling status should never exceed a certain limit. Other constraints for the state and control variables, such as a maximum bound for the volume produced per cycle are also incorporated in the optimization problem. Numerical results are presented, where optimal production flows, times and cleaning intervals are calculated by means of a generalized simplex algorithm.
