A reverse osmosis system is a filter that takes out salt along with other inorganic matter that may be in your water. The process is also referred to as desalination, How Stuff Works explains.
How it works
Water passes through a fine membrane, which filters out contaminants. This makes it easy to collect water from the permeate side of the membrane, which is clear of concentrated contaminants. Because the system is ideal for removing salt, it is ideal for use in households that have salty or brackish drinking water. If your water also has large amounts of nitrates or dissolved minerals, then buying this filtration system is a sound decision.
Stages of filtration
When you have a reverse osmosis system, you can look forward to several stages of filtration. First, there’s the sediment stage which involves the removal of particles as well as rust and sand. This is followed by the carbon stage, which is all about the removal of chlorine and chemicals. Reverse osmosis stage or the removal of dissolved solids or anything larger than a water molecule follows. After all this, the water is then purified by the addition of healthy minerals to balance out the pH and improve the taste. The water will then go to the storage tank where it may be subject to optional water treatment before the final carbon stage or when the water passes through a filter that removes any contaminants that may still remain at this point.
Factors to consider
When you shop around for an RO system, make sure you factor in any the quality of the system. Is it an excellent one? Does it have glowing reviews? Test your water so you’re well aware of the contaminants you need to remove and what kind of system will work best for you.
