Get the best reverse osmosis membranes removing contaminants from water

Posted by AmandaTom on September 29th, 2013

A growing awareness about water purity has escalated the demand of water filters. There is a large variety of water filters available in the market. You can try out the water filters furnished with reverse osmosis membranes since these units promise to provide you with clean and clear water free of pollutants. Make sure that the unit you buy has other water filter parts working effectively to provide you with water that is good to taste and beneficial for health.

Reverse osmosis membranes are flimsy, semi-permeable, porous membranes that are integral parts of reverse osmosis water filter systems. A reverse osmosis membrane contains super-fine pores. What kind of impurities would be filtered through a RO membrane is determined by the size of the pores it has on its surface.

Now, the question is, how the reverse osmosis membranes function? The pores on a reverse osmosis membrane are bigger than water molecules. So, water easily passes through the tiny pores while the larger contaminants present in the water get stuck in the membrane and are separated from the water.  The capacity to separate water and the contaminants present in it is what turns the RO membrane a significant part of a filter that has RO membrane as one of its important water filter parts.

Reverse osmosis membranes are available in two varieties. They include:

•             Cellulose Triacetate Membranes (CTA): The Cellulose Triacetate Membranes are highly deliquescent. They are perfect for eliminating antibodies from water. You need to disinfect these membranes on a regular basis in order to check bacterial growth. They are cost-effective and are long lasting. Another prime benefit of the Cellulose Triacetate membranes is that they need less cleaning and are highly resistant to chlorine.

•             Thin Film Composite Membranes (TFC): The word “thin-film composite” explains the way in which these RO membranes are made up. These membranes are constructed of layers of different components attached together to create a single membrane. The layered constitution of the Thin Film Composite membrane allows the use of material combinations that enhance the lastingness and performance of the membrane. The membrane has exquisite hydrolytic resistance for better membrane stability and durability. It rejects salts and antibodies efficiently. The excellent membrane flux ensures lower pressure and higher productivity. The Thin Film Composite membrane has a greatly operating pH range (2 to 11).

Wondering about which water filter system to buy, one with Cellulose Triacetate Membrane (CTA) or a unit equipped with Thin Film Composite membrane? While CTA membrane eliminates 93 % of standard contaminants, TFC membrane has the capacity to remove about 98 % of the contaminants from the water. CTA membrane is more susceptible to the damage caused by micro organisms than TFC membrane. At present, water filters with TFC membranes have a high demand in the market. You should measure the advantages and disadvantages of both the membranes and determine which one is the better. If you want to replace the existing Reverse Osmosis membranes from your water filters, you should make sure that you buy the membranes from a reliable store. Make sure that store has other water filter parts in its stock.
