AquaSure Spring fresh DX, AquaSure Elegant RO, AquaSure Nano RO – these are RO water purifiers from the house of Eureka Forbes. You can buy any of these at leading consumer durable, home appliance and modern organized retail outlets. What is the type of RO membrane that AquaSure RO water purifiers come equipped with? It is Thin Film Composite (TFC or TFM) membrane. This is the membrane used in most of the domestic RO water purifiers in India and across the world. Then there is another type of membrane called the Cellulose Triacetate (CTA) that is also used.
Why AquaSure RO water purifiers use TFC rather than CTA? This is because TFC is more advantageous than CTC. Key differences between the two types are on chlorine tolerance and filtration ability and chlorine tolerance. You will come across information on TFC not being chlorine tolerant compared to CTA. This is right. And with almost all municipal water supply systems being chlorinated, many may question the ability and effectiveness of TFC. Well, AquaSure RO water purifiers come equipped with special carbon pre-filters to check chlorine during the purification process so that it doesn’t reach the membrane. Millions of users bank upon AquaSure RO water purifiers. These are certified by numerous global certification bodies for purification effectiveness, quality, and technology incorporated.
TFC membranes are less susceptible to bacterial fouling and reject 98 percent of standard contaminants. The CTA membrane is chlorine tolerant, but rejects 93 percent of standard contaminants and is more susceptible to bacterial fouling.
