Under Counter Reverse Osmosis Water Filtration System

A Reverse Osmosis water system works on a simple and straight forward process. It pushes water with high pressure through a semi-permeable membrane which filters out impurities. During the process, the contaminants like the majority of dissolved salts, organic matter, bacteria, and pyrogens do not pass the filter membrane get flushed out of the system leaving pure drinking water for the user. Reverse Osmosis water filtration systems are not new. In fact, the American population has been using Reverse Osmosis water filters since 1977 and is still considered one of the most effective methods to purify water.

How Reverse Osmosis Water systems work

A reverse osmosis system usually works in 4 stages of filtration or even more to provide optimum water quality:

Stage 1 – Sediment Filter

The sediment filter is also known as pre filter which is designed to strain out the macro contaminants like dirt, silt and sediments. They make the further process of filtration easier by stopping the macro contaminants from reaching the delicate layers of filter membrane.

Stage 2 – Carbon Filter

A carbon filter is designed to filter chlorine which is abundant in municipal water especially in the metro cities of America. Carbon filters also remove unpleasant odors and taste from water.

Stage 3 – Reverse Osmosis Membrane

The reverse osmosis membrane is the most delicate and essential part of reverse osmosis filtration systems. It allows pressured water through it but blocks almost every contaminant as small as 0.25 microns.

Stage 4 – Polishing Filter

The polishing filter is the last stage which provides additional filtration to remove essentially any left-over minerals, odor and taste to provide polishing to the filtered water which is optimum for daily drinking purpose.

Additional Process

All the contaminants are removed using water that flows back through all the membranes to flush them out through a drain valve. This increases performance of the filters and prevents blockage of the membranes. A good reverse osmosis water filtration system provides up to 99.5% of clean drinking water.
