Nanofiltration Water Purifier


Nanofiltration works by excluding particles based on size. It uses a membrane with smaller holes compared to microfiltration or ultrafiltration. This lets it selectively remove certain substances, such as organic molecules, some salts, and larger ions. At the same time, it allows smaller molecules and some salts to pass through.

In contrast, reverse osmosis relies on pressure to push water through a special membrane. This removes various contaminants, like bacteria, viruses, dissolved salts, heavy metals, and other impurities. The RO membrane has even smaller holes than the nanofiltration membrane, effectively blocking almost all contaminants and producing purified water.

When combined in a water purifier, nanofiltration and reverse osmosis effectively remove a wide range of impurities. First, water goes through the nanofiltration membrane, which selectively filters out certain contaminants, including larger organic molecules and some salts. Then, the water flows through the reverse osmosis membrane, further eliminating smaller molecules, dissolved salts, and other contaminants.

As a result, you get highly purified water, free from most impurities like bacteria, viruses, organic compounds, salts, and other contaminants. The performance and capabilities of an NF-RO water purifier can vary depending on the design, quality of the membranes used, and operating conditions.

NF-RO water purifiers find common use in various applications, such as residential, commercial, and industrial settings. They provide a reliable and efficient method to obtain clean, safe, and purified water for drinking, cooking, manufacturing processes, and other purposes where high-quality water is required.
