Abstract:
Method for on-line prediction of performance of an RO based desalination plant is disclosed. The method includes: (i) a mathematical model of the RO unit; (ii) on-line estimation of membrane physical parameters of the nonlinear mathematical model representing the RO unit; and (iii) analysis of the estimated membrane transport parameter with respect to time. Based on the analysis of these estimated parameters, plant operators can clean the membranes to restore the performance of the RO desalination plant. The method can be implemented in a computer based control system used for data acquisition and control of an RO based desalination plant. The method can help in maintaining the performance of the RO based desalination plants at a desired level and increase membrane life without affecting quality of permeate water produced.
