Reverse osmosis, as the name suggests, reverses this natural process. By applying external pressure exceeding the natural osmotic pressure (typically provided by a high-pressure pump), water molecules are forced to pass through the RO membrane from the high-concentration side (containing impurities like raw water) to the low-concentration side (produced pure water). Dissolved salts, ions, heavy metals, bacteria, viruses, and other impurities in water—being significantly larger than water molecules—cannot pass through the ultra-fine pores (typically 0.0001 micrometers) of the RO membrane. These contaminants are thus retained and discharged with the wastewater.

Reverse osmosis water (RO water) is produced by treating raw water sources like tap water or well water through reverse osmosis technology. This process effectively removes over 95% of dissolved salts, organic compounds, bacteria, viruses, and other impurities, resulting in water with exceptional purity that meets stringent quality standards.

Advantages of Reverse Osmosis Water:

1. Safe and Efficient Filtration: Can remove up to 99% of impurities in water, including heavy metals, chlorides, nitrates, arsenic, and lead. It also eliminates harmful radioactive particles, organic compounds, fluorescent substances, pesticides, and other contaminants, ensuring safe drinking water.

2. Improved Taste: Eliminates excess minerals and chemicals, resulting in a purer taste and softer texture compared to regular tap water. Perfect for soups, tea brewing, coffee preparation, and more—preserving original flavors while breaking down nutrients for better absorption.

3. Versatile Applications: Suitable for homes, commercial offices, medical facilities, laboratories, electronics industries, and various settings.

4. Eco-Friendly: Although RO machines produce wastewater, they significantly reduce plastic waste compared to bottled water. This cuts down on plastic bottle usage and white pollution. It also lowers carbon footprint by avoiding energy consumption and emissions from bottle production, transportation, and storage.

In summary, the greatest advantage of reverse osmosis water lies in its ability to provide the highest level of household drinking water safety assurance, while enhancing taste, daily life quality, and appliance maintenance. Despite controversies surrounding mineral removal and wastewater generation, its exceptional purification performance remains unmatched by other household water treatment technologies. For areas with hard water and higher pollution risks, reverse osmosis technology stands as the optimal choice for ensuring safe drinking water.
