The latest development and application of seawater desalination reverse osmosis membrane technology


Reverse osmosis membrane (R0) technology is one of the most powerful tools to solve the water crisis in the world. Reverse osmosis membrane desalination process energy-saving and high desalination are two issues to be met, however, there is a gap between the water-producing characteristics and the removal of solute balance, while meeting will be more difficult. Toray positron annihilation time-of-flight spectroscopy (PALS) analysis of pore size, which concluded that the pore size and R0 film on the removal of boron showed a correlation. The surface morphology and morphology of RO membrane were analyzed by transmission electron microscope (TEM), and the parameters affecting the water permeability of membrane were obtained.


Based on the above research results, we have made great progress in the application of molecular design techniques to the development of high performance RO membranes for seawater desalination, both in terms of solutes removal and water permeability of RO membranes. At the same time, the innovative seawater reverse osmosis membrane was developed using these findings and has been applied in the world's largest seawater desalination project (Magtaa, Algeria, 500000m3 / d) and China's largest seawater desalination project (Qingdao, 100000m3 / d).
