Direct capillary nanofiltration — a new high-grade

Capillary nanofiltration (NF) enables raw water to be treated in a single step to produce high quality permeate. The permeate can be used as process water for the industry. Trial studies show that a stable operation is achievable using capillary NF without pretreatment (in other words direct NF), that the technique saves energy, that there is a

Direct capillary nanofiltration - A new high-grade

In recent decades, nanofiltration (NF) is considered as a promising separation technique to produce drinking water from different types of water source. In this paper, we comprehensively reviewed the progress of NF-based drinking water treatment, through summarizing the development of materials/fabrication and applications of NF membranes in

Capillary nanofiltration (capNF) for drinking water treatment

Capillary nanofiltration (capNF) is a new alternative membrane concept available on the market – the membrane technology of Pentair and NX filtration are examples. These membranes do not have many of the known drawbacks of reverse osmosis membranes, and, as long as desalination is not required, the capNF membranes are perfectly suitable.

Nanofiltration (NF) - DuPont

Nanofiltration (NF) is a membrane liquid-separation technology sharing many characteristics with reverse osmosis (RO). Unlike RO, which has high rejection of virtually all dissolved solutes, NF provides high rejection of multivalent ions, such as calcium, and low rejection of monovalent ions, such as chloride.
