In recent years though, whole-house reverse osmosis (RO) systems have emerged as a solution to handle water quality concerns like the ones mentioned above. These systems use advanced filtration technology to remove impurities and contaminants from water, providing clean, purified water to a growing number of homes.

In this ultimate guide, we’ll delve into the intricacies of whole-house reverse osmosis systems, exploring how they work, their benefits, considerations before installation, and much more.

What is Reverse Osmosis?

Reverse osmosis is a water purification process that removes contaminants from water by passing it through a semipermeable membrane. 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.

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.

Reverse osmosis systems generally consist of multiple stages of filtration, 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.
