Household 2012-150GPD RO Membrane for Water Treatment Membrane Element
Polyamides include aliphatic polyamides and aromatic polyamides. In the 1970s, aliphatic polyamides were mainly used, such as nylon-4, nylon-6 and nylon-66 membranes; At present, aromatic polyamide film is most widely used. The membrane materials are aromatic polyamide, aromatic polyamide hydrazide and some nitrogen-containing aromatic polymers.
The aromatic polyamide membrane can adapt to a wide pH range of 2~11, but it is very sensitive to free chlorine in water.
The film that is selective to the substances that penetrate is called semi permeable membrane. Generally, the film that can only penetrate the solvent but not the solute is called ideal semi permeable membrane. When the same volume of dilute solution (such as fresh water) and concentrated solution (such as salt water) are placed on both sides of the semi permeable membrane, the solvent in the dilute solution will naturally pass through the semi permeable membrane and spontaneously flow to the side of the concentrated solution. This phenomenon is called penetration.
