Frequently Asked Questions About Nanofiltration Membranes to Help You Choose the Right Product
What is the difference between household nanofiltration membranes and industrial nanofiltration membranes?
Household nanofiltration membranes are mainly designed for residential water purification applications. They focus on safe drinking water while retaining beneficial minerals. Their water output is relatively smaller, making them ideal for daily drinking water systems, kitchen purifiers, and other household applications.
Industrial nanofiltration membranes are mainly designed for industrial production and large-scale water treatment applications. They focus on system stability, treatment efficiency, and continuous operation. With larger membrane areas and higher water production capacity, they are suitable for industrial separation, concentration, and purification processes.
When can nanofiltration membranes be used?
In household applications, nanofiltration membranes are an ideal choice when you want to remove harmful contaminants while retaining certain beneficial minerals in the water. They are widely used in mineralized drinking water systems and household water purifiers.
In industrial applications, nanofiltration membranes are widely used in pharmaceutical production, pesticide manufacturing, food processing, and fine chemical industries due to their excellent selective separation performance. For example, in pesticide production, nanofiltration membranes can be used for the separation, purification, and concentration of amino-oligosaccharide biological pesticides. In pharmaceutical production, they can also be used for the efficient separation and purification of small molecular compounds.
Why is there no water output after installing a new membrane?
If there is no water output after installing a new membrane, the first thing to check is whether the membrane element has been installed correctly. One of the most common causes is incorrect installation direction, such as the “O-ring” being installed in the wrong direction, which may prevent proper sealing and normal operation.
It is recommended to check the following points:
- Check whether the “O-ring” direction is correct;
- Check whether the membrane element is fully inserted into the correct position;
- Check whether there are any foreign objects inside the pressure vessel;
- Check whether the system operating pressure meets the membrane’s working requirements.

Types and Features of YIME Nanofiltration Membranes
Household Nanofiltration Membrane
Nanofiltration (NF) is a relatively advanced membrane technology, typically applied to water with low total dissolved solids (TDS), such as surface water and fresh groundwater. Its primary purpose is water softening (removal of multivalent cations) and the reduction of disinfection by-product precursors, including natural organic matter (NOM) and synthetic organic compounds.
Household nanofiltration membrane elements are suitable for desalination of water sources with TDS below 500 ppm. They offer high rejection of organic matter, microorganisms, and most divalent or higher-valence metal ions, while allowing partial retention of beneficial monovalent ions. These membranes are widely used in residential water purifiers, mineralized drinking water systems, and other small-scale applications.
Industrial Nanofiltration Membrane
Industrial nanofiltration (NF) membranes are widely applied across industries such as landfill leachate treatment, paper manufacturing, textile dyeing, and nuclear facilities, where efficient color removal and COD reduction are essential. These membranes offer selective separation capabilities, allowing the retention of beneficial minerals while effectively removing organic contaminants and harmful substances from complex water streams.
Unlike traditional treatment methods, nanofiltration operates without chemical reactions or heating, ensuring that biological activity is preserved throughout the process. This makes NF an environmentally friendly and energy-efficient solution, as it typically requires lower operating pressure compared to reverse osmosis systems. As a result, it significantly reduces energy consumption and operational costs while maintaining high treatment performance.
With its unique balance between permeability and selectivity, nanofiltration has become an essential technology in modern water treatment. It is extensively used in drinking water production, as well as in the food, pharmaceutical, and biotechnology industries for purification, concentration, and separation processes. By integrating advanced NF membrane technology with system design, YIME provides reliable and sustainable solutions tailored to diverse industrial water treatment challenges.
Industrial Nanofiltration Membrane
Industrial nanofiltration (NF) series are widely used in decolorization and COD removal processes across industries such as landfill leachate treatment, paper manufacturing, textile dyeing, and nuclear facilities. With excellent selective separation performance, nanofiltration membranes can efficiently remove organic pollutants and harmful substances while effectively retaining beneficial minerals.
During the separation process, nanofiltration membranes require no chemical reactions or heating, and they do not damage the biological activity of the substances being treated. With the advantages of low operating pressure, energy efficiency, and stable performance, nanofiltration technology has been widely applied in drinking water production, as well as separation, purification, and concentration processes in the food, pharmaceutical, and biotechnology industries.
