How Reverse Osmosis Works

Reverse osmosis (RO) is a highly effective water filtration process designed to remove dissolved substances, contaminants, and impurities from water.

The process works by applying pressure to force water through a semi-permeable membrane. This membrane is engineered to allow only water molecules to pass through, while blocking dissolved solids such as salts, minerals, and other contaminants. By pushing water through the membrane under pressure, reverse osmosis operates in the opposite direction of natural osmosis, effectively separating clean water from unwanted substances.

As a result, contaminants are left behind and flushed away, while purified water is collected for use.

Filtration Performance

Reverse osmosis is widely recognized as one of the most efficient filtration methods available:

• Removes approximately 85% to 98% of total dissolved solids (TDS)
• Effectively reduces salts, heavy metals, and other dissolved contaminants
• Removes bacteria and viruses, which are significantly larger than dissolved ions

While RO systems are highly effective, certain dissolved gases—such as oxygen or hydrogen sulfide—may pass through the membrane due to their molecular properties.

Why Reverse Osmosis Matters

Reverse osmosis provides cleaner, better-tasting water by significantly reducing contaminants that can impact health, odor, and overall water quality. It is an ideal solution for drinking water applications where higher purity is desired.
