Selecting Filtration Systems

Drinking water is one of the best methods of replenishing your body; some people claim that drinking clean water at certain times of the day even helps prevent illnesses down the line. When you are looking to provide clean water for your loved ones without the strain of using bottled water, you need an effective filtration system that uses reverse osmosis (RO) membranes. RO membranes are used to block impurities in the water and bring them out through a different channel. Residential RO membranes fall under two categories:

The cellulose triacetate (CTA) membrane is usually seen in municipal water systems, and even then it’s only applicable when the water has been chlorinated. CTA mechanisms comprise a pre-sediment filter, the membrane itself, and a set of filters that have carbon in them. While some RO water systems are affordable, there’s always a danger of getting quality water in small amounts.


Thin film composite (TFC) RO membranes are just as effective in filtering water for consumption. They are also the reverse of CTA membranes in the sense that they cannot be used for chlorinated water lest they be damaged. As such, TFC membranes have carbon pre-filters positioned ahead of them in the pipeline to strip the chlorine from the water. TFC membranes need regular maintenance to keep the entire filtration system in peak condition.
