What is Nanofiltration（NF）Systems？
NF is a green water treatment technology. It is typically used to remove substances in the range of 0.5-10 nm, allowing small molecules of organic matter and monovalent ions to pass through. The cost of the equipment is low, with very low energy consumption and low operating costs.
NF membranes have excellent properties such as thermal stability, acid resistance, alkali resistance, and solvent resistance, high concentration multiplier, pollution resistance, high membrane flux, and low operating pressure. Therefore, it can replace the traditional costly and tedious water treatment methods in some fields.
Nanofiltration systems are widely used in industries such as electronics, food, domestic wastewater treatment, petroleum industry wastewater treatment, and pharmaceuticals.

How does Nanofiltration Plant Work?
Nanofiltration is a liquid-liquid separation method that utilizes the difference in the selective osmosis performance of the membrane for each component of the mixture. By using external energy or chemical potential difference as a driving force, salts and small molecules will pass through the nanofiltration membrane, while large molecules are retained by the pressure difference. It is also known as “low-pressure reverse osmosis” or “dilute reverse osmosis”.
Its filtration capacity is between ultrafiltration and reverse osmosis, and is mainly used for the concentration and purification of large molecules in solution.
NEWater High-quality NF Membranes:
NF membranes have nanometer-sized pores and are suitable for separating dissolved components with molecular weights of 100 to 1,000 and molecular sizes of about 1 nanometer.
- Reduction of heavy metals
- Reduction of nitrate and sulfate content
- Reduces color, tannins and turbidity
- Reduction of TDS in brackish water
- Reduces pesticides and VOCs
- Lower feed water pressure.
Why Choose a Nanofiltration System?
In practical water treatment cases, 75% desalination is better than 95% to 99% desalination for some applications, especially if the water treatment goal can be achieved using only half the energy. Nanofiltration is therefore the preferred choice for removing hardness from water without affecting the total dissolved solids content.
NF systems are currently used mainly in the water plant or industrial desalination industry, with desalination rates of 90% or more, and reverse osmosis desalination rates of 99% or more. If the requirements for water quality are not particularly high, the use of nanofiltration systems can save a lot of costs.

NEWater Project Cases of Nanofiltration Systems
Due to the long-term accumulation of leachate, there is a great change in the water quality of a domestic waste plant. As a result, the leachate treatment equipment cannot operate normally and the effluent water quality cannot meet the requirements. The focus is on the problems that existed before the renovation such as adding external ultrafiltration and nanofiltration membranes.
Electroplating wastewater contains heavy metal ions, cyanide and other pollutants, which are extremely harmful to the environment and human body if discharged directly without treatment. Membrane separation technology can achieve zero discharge and resourceful reuse of electroplating rinsing wastewater, while reducing pollution and production costs.
High-salt wastewater of coal chemical industry mainly comes from the drainage of desalination water system, gas washing wastewater, circulating water system drainage and concentrated water of water reuse system in the production process. The combined process of pretreatment – nanofiltration separation – reverse osmosis concentration – evaporation/freezing crystallization is mainly adopted to realize zero discharge of high-salt wastewater.

Nanofiltration, between ultrafiltration and reverse osmosis. While nanofiltration and reverse osmosis systems have similar designs and operational uses, there are some differences between the two.
Nanofiltration (NF) is similar to a bridge between ultrafiltration and reverse osmosis membranes in water treatment. NF membranes have pore sizes ranging from 0.01 to slightly less than 0.001 and are therefore also known as “softening” membranes. Nanofiltration is not as stringent as reverse osmosis, it can work with relatively low feed water pressure, and it cannot remove singly charged ions from water as reverse osmosis membranes can. Typically NF membrane systems allow more salt to pass through than RO membranes, which may have a desalination rate of 80% or less, with hardness removal typically remaining above 90%, while reverse osmosis systems can remove up to 99% of chloride and sodium.
