How RO removes impurities

Reverse osmosis (RO) performs a highly effective purification process to ensure your water is exceptionally clean. This advanced system follows several key steps to eliminate contaminants:

  • Pre-filters clean water: Initial filters remove larger particles, dirt, and chlorine, protecting the main RO membrane.
  • Pressure forces water through: A pump applies pressure, pushing the water towards the special membrane.
  • Membrane blocks impurities: The semi-permeable membrane has tiny pores, allowing only pure water molecules to pass through.
  • Contaminants are flushed away: Dissolved salts, heavy metals, and other impurities remain on the membrane's surface and are diverted as wastewater.

How RO water is safe and healthy

Reverse osmosis (RO) purified water offers substantial benefits for your health and safety by ensuring exceptional purity. Here is why RO water is considered a healthy choice:

  • Removes harmful contaminants: RO effectively eliminates dissolved solids, heavy metals like lead and arsenic, pesticides, and other chemical pollutants from your drinking water.
  • Filters out microorganisms: The fine RO membrane can block microscopic bacteria and viruses. This significantly reduces the risk of waterborne diseases.
  • Improves taste and odour: By removing impurities and chlorine, RO enhances the water's taste and eliminates unpleasant odours. This encourages better hydration.
  • Provides pure base for diet: While RO removes some minerals, a balanced diet typically provides essential nutrients. Many modern RO purifiers also re-mineralise the water for added health benefits.

What does RO stand for in water purification?

RO stands for reverse osmosis. It is a purification technology that uses a semi-permeable membrane to remove ions, unwanted molecules, and larger particles from drinking water. This process ensures the water becomes exceptionally clean and pure for consumption.

How does reverse osmosis remove impurities?

Reverse osmosis removes impurities by forcing water under pressure through a fine, semi-permeable membrane. This membrane allows only pure water molecules to pass, while it blocks dissolved solids, chemicals, heavy metals, and microorganisms. The rejected impurities are then flushed away as wastewater.

Is RO water safe for drinking?

Yes, RO water is safe for drinking. It effectively eliminates harmful dissolved contaminants, chemicals, pesticides, heavy metals, and microscopic organisms, significantly reducing health risks from waterborne impurities. Many modern RO purifiers also add back essential minerals for enhanced health benefits.

What are the disadvantages of RO?

Disadvantages of reverse osmosis include wastewater generation during the purification process. It also removes beneficial natural minerals, though some purifiers address this with re-mineralisation. RO systems can have higher initial costs and require regular filter replacement, adding to maintenance expenses.
