Abstract：

Through the analysis of online monitoring running test on a long process reverse osmosis system, the variations of the membrane parameters such as feed water pressure, salt permeability, pressure drop and membrane flux in organic, inorganic and complex pollution were compared.The influence of membrane system operating parameters by calcium sulfate pollution and humic acid pollution were defined, system damage caused by the composition of humic acid complexation with calcium ions were pointed out in particular.
