A reverse osmosis water filter is on option in home water filters which has been used with high success for many years now.
Reverse osmosis is a very complicated chemical and technical procedure which basically involves forcing water through a semipermeable membrane. (A semipermeable membrane will let some atoms and molecules through but not all) the water is forced through this membrane and the end result is cleaner water.
This method of treating water has been around for years and is still used in some places. The drawback to this form of filtering is that it is not very economical. Only about 5% of the water is left that is clean and contaminant free. It is for this reason that other methods of filtration are often used now.
Reverse osmosis needs a lot of forced water in order to work properly and it is a method that can be quite slow. The method definitely works, just perhaps not as efficiently or quickly as some of the other methods of water filtration.
History Of RO Filtering
This method of filtering water has been around since 1970. The process has always been best known for removing salt from seawater to provide drinking water.
Though first used for industrial uses, it then became common for medical and industrial applications until finally it was used domestically. The theory of osmosis has been around for a long time. Osmosis is what happens to the human body when sea water is consumed.
The body releases water to combat the salt water and eventually dehydrates. The opposite process is used for reverse osmosis. The clean water is separated from the salt water through this semi permeable membrane that does not allow the salt and contaminants through.
RO In The Scheme of Things
There are still many places that use this method of water purification and studies are being done to try to make it more efficient. Overall, it is an excellent way to purify water and technology continues to improve upon it.
Other methods such as point of entry filters and refrigerator filters are being used much more often, however. Filters that attach right at the water tap are becoming very common in homes today. It is possible to get whole house water filtration as well.
The Reverse Osmosis water filter continues to be high on the list of home water filtration options, simply for their proven abilities to purify water.
They are one of many systems that you want to consider, but do consider all aspects of such a system and look for the more economical and efficient system available for your budget.
