The pore size of a nanofiltration filter is about 0.001 microns. Most organic molecules, almost all viruses, most naturally occurring organic debris, and a variety of salts are all removed using nanofiltration. Nanofiltration is frequently used to soften hard water because it removes the divalent ions that cause it to be hard.
These bacteria are removed by nanofiltration together with the majority of naturally occurring organic debris and a few minerals, particularly the divalent ions that are the source of hard water. However, nanofiltration does not get rid of dissolved substances.
In NF membrane, Brother Filtration can provide three different types of membranes for diverse applications. Based on the characteristics of industrial water, municipal water, and material separation.
The NF membrane has a large filtration area which has high efficiency and helps to reduce costs. Brother Filtration cares not only about the quality of the membranes but also pays attention to the preservation of membranes. A better package offers better performance!

The pressure-driven membrane method known as nano-filtration falls between reverse osmosis and ultra-filtration in terms of separation level. It is also competitive membrane filtration method.
The liquid industry is never where we stop. Additionally, we are seeking for solutions for oil and air.
The pores of nano-filtration membranes are about 1 nm in size. The retention of loaded and unloaded particles is a defining characteristic of nano-filtration membranes. Experimental filtration studies using carefully chosen molecules can be used to measure the retention of a nano-filtration membrane. For loaded particles, a basic salt solution (NaCl or Na2SO4) is chosen. For unloaded particles, polysaccharides (dextrines) or polyethylene glycols (PEG) of different molecular weights are chosen. A typical nano-filtration membrane has salt retention that is far lower than, for instance, reverse osmosis, while ultra-filtration has salt retention of zero.
Ion selection is a feature of nanofiltration membranes. This is the capacity to differentiate between various ions. Electrostatic repulsion/attraction forces between the elements in the liquid and the (nano-filtration) membrane surface may occur, resulting in a certain level of ion selectivity. This is because a nano-filtration membrane gathers solid loaded groups in its membrane structure. These ions are predicted to diffuse across the membrane based on the sieve effect (pore size 1 nm) and the molecular sizes of chlorides (0.12 nm) and sulphates (0.23 nm). Despite this, the retention for sulfates and chlorides is minimum 90% and 90%, respectively.
