BlueOcean - Nanofiltration Membrane (NF)

Nanofiltration membranes are also called “softening membranes” because they can remove the heavy metals from feed water but leave the majority of the lower molecular weight ions in the water.

Nanofiltration membranes can remove large organic molecules with molecular weight above about 1000 Daltons such as color from water. Nanofiltration membranes can also remove bacteria and virus.

With above capabilities and lower power consumption, NF membrane has been widely used for drinking water production, this is because that NF can remove heavy metals, bacteria, virus and large organics in the feed water, while retaining healthy minerals in the permeate (drinking) water.

Other applications are:

1. Removal of sugar from syrups and juices
2. Removal of hardness from process water.
3. Recycling of process water so that it can be reused instead of being discarded as waste
