Polyamide Ro Membrane

You may have noticed that many of our RO membranes say "material: aromatic polyamide composite membrane". Polyamide is the name of this material. It is the most common material in the RO membrane industry today. Almost all major brands use it. America's Dow uses it. Japan's Hydranautics and Toray use it. Our product size is 8040. That is the standard size for industrial pressure vessels. You can put our membrane into any standard housing. It will fit perfectly. You do not need to worry about compatibility.

There are several reasons why polyamide is so popular. First, the rejection rate is high. It removes more than 99% of salt from water. Second, the chemical stability is good. It is not afraid of acid or alkali cleaning. Third, the mechanical strength is good. It can handle high pressure without breaking. Fourth, the cost is reasonable. The performance to price ratio is the best available. So do not worry. Our polyamide ro membrane is a very mature product. Our research team has worked on polyamide membranes for decades. We know this material very well.

Our product comes in many types. We have high flow types that produce more water. We have low energy types that save electricity. We have high rejection types that give very pure water. We have low pressure types that work with smaller pumps. We have brackish water types for salty well water. We have seawater types for the ocean. You name the need. We have the membrane. We do not sell just one type. We listen to your water quality and your needs. Then we pick the right polyamide membrane from our full line. No more. No less.
