Whole House Reverse Osmosis Systems: The Ultimate Guide
What is Reverse Osmosis?
Contaminants are removed from water through the reverse osmosis process by passing the water through a membrane that allows only specific molecules to penetrate. The membrane acts as a barrier, only allowing water molecules to pass through while blocking larger molecules such as dissolved salts, minerals, and other impurities. The result is clean, purified water free from contaminants and safe for consumption.
How Does Reverse Osmosis Work?
A – Pressure
B – High concentration solution
C – Flow build up
D – RO Membrane
E – Low concentration solution
F – Filtered water
The reverse osmosis process works on the principle of osmosis, where water naturally moves from an area of lower solute concentration to an area of higher solute concentration through a semipermeable membrane. In reverse osmosis, pressure is applied to the side of the membrane with higher solute concentration, forcing water molecules to move in the opposite direction, from the concentrated solution to the dilute solution.
Whole house reverse osmosis water filter systems generally consist of multiple stages of a filtration system, each designed to target specific types of contaminants. These stages may include pre-filters to remove sediment and larger particles, activated carbon filters to adsorb organic compounds and chlorine, and the semipermeable membrane for removing dissolved solids and other impurities. Proper pre-treatment is essential for maintaining the longevity and effectiveness of the system, ensuring it lasts 15-20 years.
