It is applicable for the removal or concentration of dye, removal of heavy metal and the concentration and desalination of whey protein. It will intercept divalent ions and higher ions preferentially, the interception of monovalent ions will be affected by the liquid concentration. This membrane model was widely applied to the desalination and decoloration treatment on the raw water, such as surface water, landfill leachate, dyeing wastewater, coking plant waste water, etc.
