Water Treatment Part 3

Ok so this is the step that gets really interesting. This mid-step is the one that removes the majority of unwanted particles from the water. This step is where RO or reverse osmosis takes place.

Now I'm going to paraphrase here because some of this process is pretty hairy i.e. complicated. The main idea that is osmosis, more or less, is the natural tendency for areas of lower solution concentrations filter to areas of higher solution concentration to equalize naturally. In our case the solution is water. We of course aren't doing osmosis but reverse osmosis. In other words we are forcing the area of higher solution concentration to an area of lower concentration i.e. water with impurities to an area without impurities. More or less this is the process using pumps and RO membranes the water is purified. The particular RO unit that we employ is capable of providing up 95 percent + of total dissolved solids.
