  • Nanofiltration The Up-And-Coming Membrane Process
    called loose RO and RO UF hybrid membranes Hence a new category of membrane performance was realized Further what if the ions dissolved salts that a municipality wanted removed for potable water were only the hardness ions and the added pressure that the tight RO membranes required was an unnecessary cost The earliest documented application of NF was a potable water application in Florida in the late 1970s and was probably the first commercial intentional use of such NF membranes The loose RO membrane chosen required less pressure because it allowed monovalent ions like sodium to pass through yet still removed color molecules and probably unrealized at the time tri halo methane precursor molecules This membrane softening application was born before the term nanofiltration was known In 1983 the first documented process NF membrane as opposed to water treatment I have found was commercialized for the purpose of desalting a small food grade dye an advantageous purification step in a critical manufacturing process This membrane is documented well because coincidentally the patented use it was developed for became the basis of a major patent law interpretation case which made it to the U S Supreme Court after 12 years in the lower courts decided in 1997 A New Membrane Class Is Born In 1984 Dr Peter Eriksson in a marketing contribution to differentiate such new membranes coined the term nanofiltration which he based on the estimated size of the pores in a membrane with these types of removal characteristics Thus a fourth class of pressure driven membranes was born This term and the fractionation process came into widespread use long before the nano materials storm that has recently swept the technology world The only connection the NF membrane name has to nanomaterials is through the smallest size of uncharged solutes they tend to separate a weak link The ability to separate some small solutes from others is a very important membrane characteristic Keep in mind that there are two types of solutes separated by differing mechanisms ions based chiefly on their valence state in water charge and sieving based on molecular weight if uncharged This is a simplified definition that is generally not universally accepted It seems that those industry groups that mainly purify water think only of the ionic separation performance of NF as important and often ignore the uncharged solute aspect in their definitions and common usage Yet some of the most creative and technical applications for NF involve removing one size uncharged molecule from a larger or smaller solute to achieve an otherwise difficult separation Such a process step is called fractionation and is employed in technical applications for food and beverage ingredients fine chemicals oil and gas i e fracking pharmaceutical and biomedical applications There will undoubtedly be more applications since the interest in using membranes is growing even faster now than in the 1980s Many of these successful fractionation applications are kept silent as trade secrets or only show up in issued patents or patent
