How your reverse osmosis system works

Reverse osmosis filtration is the best way to remove contaminants from your water source. Reverse osmosis may sound complicated but its actually quite simple.

Your High Pure Water system is composed of multiple filtration stages. The first two stages are used to extend the life of the R.O. membrane.  

Sediment filtration

The first stage is the sediment filter. Sediment filters work very similar to coffee filters. This filter removes silt , dirt and debris smaller than 5 microns

5 Microns is small enough to filter out red blood cells. 

Sediment filtration is a necessary process which extends the life of the R.O. membrane.   Without sediment filtration the final R.O. filtration membrane would clog fairly quickly.

 

Organic chemical filtration

The second stage is a carbon filter. The High Pure Water carbon filter uses activated coconut carbon. These filters are capable of absorbing some chemicals and most volatile organic compounds.
Carbon filters can remove chlorine, ethanol, butane, and most organic odor causing compounds. The carbon filter stage helps to protect the R.O. membrane but also removes small molecules that may pass through the membrane.

Reverse Osmosis Stage

The R.O. membrane is the last stage in the filtration system.  R.O. membranes work very similar to a coffee filter as well.  They are made of materials that are so tightly woven that not much more than water molecules can get through. 
Because the materials used to make the R.O. membrane are so tightly woven, pressure is needed to push water through.  Anything bigger than a water molecule is rejected and carried away to a waste tube.
The Industry standard waste to clean water ratio is 4:1. This means that most R.O. units produce 4 parts waste water to one part clean water.  The Piranha 100 produces half that,  2:1.
