Reverse Osmosis Water Filter Systems

Not all water filter systems are the same. All systems work on the principle of directing in flow fluid so that it passes through a membrane or mesh which in turns extracts impurities from it. The goal is to be able to get rid of the impurities that are harmful to your health. A byproduct is that the liquid then becomes more attractive to consume because of its visual clarity, pure taste and fresh smell.

Simple set ups will only get rid of impurities of larger size, twigs and leaves for example, which might cause blockages in the supply line or fester in a holding tank tank if it is to be stored. The membrane size will determine which and how many of the contaminants are removed. It stands to reason that the smaller the filter the greater the number of contaminants that can be eliminated.

Some systems may need to employ a number of filters in the water line with deceasing membrane sizes each filtering out different materials. This is necessary to reduce clogging in the smaller meshes and thereby increase the efficiency of the system. This is all very well but there comes a time when the membrane size becomes such that the medium flow through it may be reduced to a dribble because of the membrane resistance.

These hyper filters then need to employ a technology to overcome this problem. Reverse osmosis is such a technique that can be employed to increase the fluid pressure on the inflow side. This forces the fluid through the dense membrane and at the same time can remove the trapped contaminant particles.

This is often achieved by employing a reverse osmosis unit. These can raise the pressure of the fluid on the inflow side to achieve an acceptable outflow after passing through the fine membrane. These systems can also manage to dispose of the contaminants on the in flow side of the system thereby increasing the system’s efficiency.

This technique of purification was originally devised to extract fresh H2O from the sea by filtering out the harmful salts. It has gone on to be the chosen system for use in some large municipal desalination plants. It is also and is often used by the military to provide clean liquid in hostile and unsanitary environments.

Thankfully smaller domestic scaled reverse osmosis water filter systems are available at reasonable cost. They are slightly more bulky the familiar standard under sink filter but for not much more can provide a better cleaner product.

You can have all the fresh pure water you need by installing a reverse osmosis water filter. There are several great water filter systems available online.
