Nanofiltration Technology Services
Nanofiltration membrane is a pressure-driven membrane between ultrafiltration membrane and reverse osmosis membrane. Due to its lower operating pressure, it allows some inorganic salts, especially monovalent salt ions, to pass through for separation and organic matter separation, has different selectivity for monovalent and divalent ions, and has high retention of small molecules (molecular weight less than 1000 Dalton) organic matter, among other features. Its transmembrane pressure (up to 3 MPa) is less than that required for reverse osmosis, thus greatly reducing operating costs. Filtration technology is based on the appropriate pore sizes on the membrane surface through which the liquid will pass. These pore sizes are typically less than 10 nm, and nanofiltration is often used to remove ions from different solutions.
Characteristics of Nanofiltration Membranes
Nanofiltration membranes are widely used in the treatment of tap water and drinking water, and in the manufacture of food, biological and pharmaceutical products. As a high-precision filtration membrane, nanofiltration membrane has the following characteristics:
- No phase change or chemical reaction in the filtration process, and no other impurities are brought in.
- It can remove salt, and a large number of common dissolved salts can be removed by nanofiltration membrane.
- High recovery rate in the process.
- Small footprint of equipment, low energy consumption.
- Easy to operate and maintain.

Why should nanofiltration membranes be cleaned regularly?
The general cleaning cycle for nanofiltration membranes is mainly based on the use of the membrane element, which is usually around three months, but when the water production of the membrane element decreases, it is time to clean the nanofiltration membrane. It is also important to be prepared for nanofiltration membrane cleaning by using high quality water without residual chlorine and other oxidants for flushing as much as possible. When preparing the cleaning solution, make sure that the cleaning chemicals are well dissolved and mixed before entering the element cycle.
