56’NanoFiltration: continued 4
• -->> cont: WM Accepted effect: P2(Watefilter):
When combined with existing filter system, it further augments performance(eg
acoustically filtrated carbon nanotube filter, permeation is not driven by conventional pressure
or even gravity). Well adopted by space agency or military, also seems coagulation
component to be capable of recovering at filter(eg; extra oil recovered while filtered water
is instantly drinkable).
• Nanofilteration used Forward Osmosis(FO) effect(FO is not at all exclusive to Nanofilters,
neither is below commercialized example) is lowest cost in some limited specific
situations: Use of osmotic power, by clean water side of membrane having higher solutes
content than dirty water side of membrane. Hence little to no power required while causing far
less membrane fouling. 、
• Cost competitive set up is made by use of draw solutions that are easily recoverable/separable/
reuseable by temperature change etc for cost reduction, so even by combining with RO, it
might still reduce costs, nutrition is kept during concentrating process(eg juice) without
heating(Oasys water, HTI water, Modern Water, Forward Water Technologies+), use of
Carbon Nanotube filter for additional significant saving(Porifera). Mechanics example of FO:
NH3 & CO2 bubbling in water produces salts with very high osmotic pressure(NH4HCO3 etc)
but easily separated/recovered when applied low grade heat. Also in certain natural situation it
might be suitable(eg dirty water cleaning to discharge into ocean, located next to desalination
reject water channel, or making heavy sugary beverage etc).
