Reverse Osmosis System-A 10 If You Need One-But Do You Need One?
Tuesday, November 18th, 2008It’s true, if you have salty or brackish water with a lot of inorganic material in it, you will be pleased with anything that will clean it up and reverse osmosis water units will. But, if you are getting your water from a municipal water system or a chlorinated well; I’ve got good news for you. There are much cheaper selective filtration systems you can get that will do a better job, and produce healthier water, than reverse osmosis systemes. In this article we will look at each system and how they work, and you can decide what’s best for you.
Reverse osmosis (RO) systems work by pushing water against a semi-permeable membrane with pores so small that only objects the size of a water molecule, or smaller, will pass through. As a matter of fact, the pores are so small they will even reject a large part of the water itself along with minerals and most contaminants. In most RO systems, the rejected water is simply wasted. Typically, this amounts to about two or three wasted gallons for every gallon filtered.
