The reverse osmosis desalination system is defined by mutual interaction between several phenomena from different
natures. Therefore, such modelling requires a unified approach to have the possibility to correlate the different
dynamic situation in our system. We performed experiments at three concentrations (10 mg/ml, 15 mg/ml and
18 mg/ml). Permeate conductivity, retentate conductivity, permeate concentration, retentate concentration, salt
permeate concentration, and salt retentate concentration were extracted according to the values of the pressure.
This paper presents a bond graph model of a reverse osmosis desalination system taking account of hydraulic and
chemical phenomena. The construction procedure was based on the law that the optimized model can be generalized
to any reverse osmosis desalination system with simple parameter variation. Simulation result.. View more»
