We have all heard of osmosis back in high school when we were studying plants and other living things and how they leach water from the soil and their environment. Just as we get water from water coolers!
The process is one you probably have not thought that much about since school. Then you start looking into water filtration systems and you start hearing all about reverse osmosis (RO) water filter systems.
You will be thinking I know what osmosis is – when a membrane separates two liquids and the lower saline water will naturally move through the membrane to the water with the higher salinity. After a while the water will have naturally balanced itself out to an equal salinity (salt content).

So you would hazard a guess that reverse osmosis is in some way similar to this. The original purpose of reverse osmosis (RO) was to remove salt from water; yes it is what they use to create fresh drinking water for large ships etc. Water is forced through the membrane from the most salty to the least salty and you end up with the salt molecules being caught in the filter as they are larger than the molecules of water which are hydrogen and oxygen.
The membrane required to do this is so fine that reverse osmosis (RO) is not just good for removing salt it is actually an incredible water filtration method – quite possibly the best available in the world today. It will give you absolutely pure water pure H2O, two parts hydrogen and one part oxygen.
It will be pure and delicious water but it will have none of the mineral content that some people prefer to have in their water for varied health benefits and taste reasons. I am happy to get my minerals from my food and enjoy the taste of totally pure reverse osmosis processed water.
