The Science Behind Reverse Osmosis

A solution with a high salt concentration is separated by a semi-permeable membrane from a solution with a low salt concentration. In normal osmosis, water molecules from the side with low salt begin permeating the membrane into the high salt concentration solution.

The natural osmosis process can be reversed and used as an environmentally friendly and naturally safe form of water purification.

In the reverse osmosis process, pressure is supplied which exceeds the osmotic pressure Of the high concentration solution – to force water molecules in the reverse direction.

 

Through this process, clean water Starts to permeate through the membrane. The clean permeate water molecules contain approximately 98% less salt than the inlet water.

 

Reverse osmosis technology removes more than 99% of the particles and bacteria from the high salt concentration. The clean permeate water molecules can be further conditioned into CAP/CLSI Type-I water.

GWT reverse osmosis specifications correspond to a water temperature of 15 degrees Centigrade. Each degree of temperature variation creates a shift in production. Other reverse osmosis systems use 25 degrees Centigrade to rate their capabilities. With GWT you are assured of high permeate production even if the temperature falls below 25 degrees. 

The production rate of a reverse osmosis system depends on water temperature.

Once the reverse osmosis process has been completed, the permeate water is ready for complete deionization. Complete deionization separates all remaining minerals, particles, and bacteria from the clean water permeate molecules. 

General Water Technologies’ analyzer feed water systems provide complete deionization and deliver CAP/CLSI Type-I water. 

Every GWT system is designed with green technology and the list Of advantages goes on. 

A GWT 4000, 8000, or 7000 Series system is an excellent choice for ultra-pure chemistry analyzer feed water.
