Understanding Reverse Osmosis Systems

The Science Behind Reverse Osmosis

Reverse osmosis (RO) is a filtration process that removes impurities from water by using pressure to force water molecules through a semipermeable membrane. This membrane acts as a barrier, allowing only water to pass through while blocking larger molecules and impurities, such as dissolved salts, bacteria, and chemicals.

The process begins with applying pressure to the water on one side of the membrane. This forces water molecules through microscopic pores, leaving contaminants behind. The purified water, known as the permeate, is collected for use, while the remaining concentrated water, carrying the rejected impurities, is flushed away or redirected.
