A reverse osmosis membrane is a semi-permeable membrane that allows water molecules to pass through it, but it blocks most of the dissolved salts, organics, bacteria and pyrogens. On the other hand, membrane contactors can only effectively remove gases such as oxygen, carbon dioxide, and ammonia in water, but cannot eliminate ions, bacteria, organic matter, or suspended solids.
Reverse osmosis membrane (RO membrane) and deammonification membrane (usually referred to as membrane contactor) are two different water treatment technologies, which are different in function and application.
Reverse osmosis membrane is mainly used to remove various impurities in water, such as salt, organic compounds, microorganisms and heat source proteins. Its working principle is to use the selective permeability of the membrane to allow water molecules to pass through and exclude the above impurities. This process can greatly reduce the hardness of water and improve water quality.
The main function of the deamination membrane is to remove gases in water, such as oxygen, carbon dioxide and ammonia. Membrane contactors allow these gases to be removed from the water by changing the pressure or chemical reaction. However, the deamination membrane usually does not have a good removal effect on ions, bacteria, organic matter or suspended matter.
To sum up, reverse osmosis membrane is a kind of water purification technology, which can remove many types of impurities in water, while deamination membrane is mainly used to remove specific gases, and has limited effect on the removal of other types of pollutants.
