Nanofiltration


Nanofiltration is the newest pressure driven filtration process and dates back to the 1970s The molecular weight cutoff of nanofiltration is in the range 150–1000 Da As a result, nanofiltration is a suitable candidate for removing inhibitory compoundsNanofiltration 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 chlorideNanofiltration is often used to filter water with low amounts of total dissolved solids, to remove organic matter and soften water Because it is a “looser membrane”, nanofiltration membranes are less likely to foul or scale and require less pretreatment than reverse osmosis systems Sometimes it is even used as pretreatment for reverseNanofiltration is a somewhat recent filtration method that depends upon membrane
