5 STAGE RO SYSTEMS

The LAB-SIL Five Stage Reverse Osmosis System is a high capacity 36 to 50 GPD (gallons per day) system designed for laboratory usage,

“Osmosis is the movement of a solvent through a semi permeable membrane into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane.”  A semi permeable membrane is a membrane that will allow some atoms or molecules to pass, but not others.

Reverse osmosis uses a semi permeable membrane. The semi permeable membrane allows the fluid that is being purified to pass through the membrane.  As it does this, it rejects the contaminants that remain.  It utilizes a technology known as cross flow.  Cross flow allows the membrane to continually clean itself off.  As fluid passes through the membrane, some of it continues downstream.  This causes the rejected and unwanted particles to be pushed away from the membrane.
Reverse osmosis requires a strong driving force to push the fluid through the membrane.  The usual way to do this is with a pump. The higher the pressure from the pump is, the larger the driving force is. As the concentration of the fluid that is being rejected increases, the driving force needed to continue concentrating the fluid increases.

Reverse osmosis is capable of rejecting salts, bacteria, proteins, sugars, dyes, dyes, and other constituents.

It is most recommended by us to be used for primary purification of water for our distillation apparatus.
