The Center’s patent of PS RO composite membrane with high flux being awarded excellent prize of China chemical industry patent in 2012.

The Center’s patent of PS RO composite membrane with high flux was awarded excellent prize of China chemical industry patent in 2012. The patent technique provides us with a new RO composite membrane with materials being easy to be achieved, cheaper price, high salt rejection and high flux; its characteristics lie in having aromatic polyamide function layer obtained from condensation compound of the interface between aromatic polyamine and aromatic polybasic acid amide, thus realizing high flux and high salt rejection of the membrane.
