What is the Reverse Osmosis Process?

Reverse Osmosis Water Purifiers use the reverse osmosis process to remove impurities from the water. Osmosis is the process whereby a solution which contains a solute (such as salt or sugar) moves from a smaller solute solution to the higher solute solution. For example, if you have a 16oz bottle of fresh water and a 32 oz bottle of salt water, the natural osmosis process will cause the fresh water to move to the salt water. This is osmosis. This is a process that occurs naturally in nature. Reverse Osmosis is not natural because it requires applied force to reverse the process and move a greater solute solution to the lesser solute solution. One of the most common applications is to use Reverse Osmosis (also referred to as RO) is the desalination (removal of salt) of sea water to create fresh water.

Household Reverse Osmosis Systems

Reverse Osmosis systems have become very popular for use in residential applications like homes. They offer the ability to remove most and often close to all impurities from the water. RO water is essentially devoid of minerals because of the process it is put through. Fans of RO systems are glad to get rid of chlorine and other chemicals from the water, some of which can only be removed by reverse osmosis. Flouride, for example, can only be removed through an RO process and is extremely toxic to humans when left in the water. RO systems are also helpful in places where the water is very hard and has a lot of excessive and unhealthy minerals in the water.

Cautions about Reverse Osmosis Water

People that use RO water often believe they are getting good water because they have removed all the impurities from the water. The trouble is, not everything that RO systems remove from water is stuff that you want removed. Some minerals are good for you. Good healthy water contains healthy minerals that your body wants and needs. When you drink water devoid of minerals, the water will leech those minerals from other parts of your body. Over time, your body can become depleted of minerals from drinking RO water. After doing the reverse osmosis process for water that needs it, you will need to use a re-mineralization filter to put the good minerals back into the water. This will start the process of making the water healthier to drink. Ideally, after re-mineralizing the water you should run the water through a water ionizer.

4-Stage and 5-Stage RO Systems

Household Reverse Osmosis Systems are typically under-counter installations. They usually come with a four stage or five stage RO process where impurities are removed. These steps usually include several carbon filters, a sediment filter, and most importantly, the RO Membrane. The RO membrane is the core filter that is used in preventing salt from moving with the water and causes it to separate out. Watt's Premier offers some of the best RO systems on the market today and they offer a few variations so you have some choice.

RO systems have a very specific purpose and they should be used accordingly to deal with salt water, hard water, fluoride, and other critical water concerns. But for many water purification needs, these systems are not necessary. So it is very important that you understand your water needs before you purchase one.
