What Is A Reverse Osmosis Water Filter

Chances are, a reverse osmosis water filter (ro) is one of the systems you will encounter when searching for a quality water filter

It works by forcing water at a pressure between 30–250 psi, through a semi-permeable membrane 0.0001 micron in size(approx 0.00000004 inch). When it comes to filters, the smaller the microns, the better the water is filtered.

The molecules of most inorganic contaminants as well as trace minerals are larger than the membrane, so they are unable to pass through it. These waste elements are then diverted to a drain so as to prevent the membrane from clogging up.

Generally speaking, home reverse osmosis water systems will include the following stages to filter your tap water:

reverse osmosis filter 1. Filter traps particles and rust

2. Optional second filter with smaller membrane traps additional sediments

3. An activated carbon filter to trap organic chemicals and chlorine that can break down the thin film composite membrane (TFM/TFC).

4. A thin film composite membrane (TFM/TFC) also removes particles. 5. An optional second activated carbon filter removes chemicals not caught by the TFM/TFC.

6. Optional ultra-violet germicidal lamp that sterilizes any microbes that may have escaped the filtration processes above.
