REVERSE OSMOSIS – PART TWO OF THREE

In the last blog post we learned what osmosis was and saw a visual of what it was. To reiterate, in Osmosis cleaner water moves from the less concentrated side of a semipermeable membrane into the side where there is contamination. The problem with this is is that we can never achieve high purity water because there will always be contaminants on both side of the membrane.

REVERSE OSMOSIS – PART ONE OF THREE

When I began designing and selling Reverse Osmosis (RO) systems circa 1975, very few people ever heard of the technology let alone understood it. Today, RO is a common technology found in many homes but many still do not understand why it is called Reverse Osmosis. So, lets take a closer look. The accompanying figure will help with the description. The key to an RO system is something called a…

Osmosis – Purifies Water and Purifies Blood

We learned before that Reverse Osmosis uses what is called a semi-permeable membrane (SPM) to purify water. An SPM is a material designed with a pore size that lets specific materials pass through it, while blocking others. In water purification the membrane allows water to pass, but blocks salts, bacteria and other solids. We also learned that when a SPM separates a highly concentrated solution from a less concentrated solution…
