While water purification systems have been around for decades, in recent years the technology and the process has evolved and there are many products on the market that use reverse osmosis or distillation to purify the water. But how does a reverse osmosis system work and how do you know it is the right system for your home? Here is a basic overview of what is involved in purifying water through reverse osmosis.

The basic principle behind reverse osmosis is the removal of sediments from the water. Sediments include minerals like calcium, magnesium, manganese, potassium and iron that are naturally present in water. These minerals are dissolved by the water''s natural osmotic pressure and the water that flows out of a reverse osmosis unit is free of these minerals.

Water that is passed through a reverse osmosis unit contains ions. The process removes these ions by using a membrane. The membranes are made up of a layer of polypyrithione that is coated w
