• 56’NanoFiltration: Effect mix of Accepted, Disputed, Generally
Rejected, Fully rejected by Western Mainstream(WM)
• ■ 56’NanoFiltration:(also see 22’Nano Material Used Filter), In many ways it is completely
mainstream tech but some other ways it is clearly underused. Generally referred as single digit
nanometer filtration(1-9nm), Similar effect as 55’Nano Material treating. Typically passes
monovalent ions i.e. by ionic size, also charge etc. But can to some extent customizeable -
selectively pass certain solutes or set directionality of flow by size and charge(RO rejects all: one
fixed way only by outside force): ie can function like biological ionic channels or super low cost
desalination if designed(nanopore size needs to be property arranged with specific material,
also at Carbon Nanotube case, water permeability is up to 4-5 orders of magnitude faster than
allowed by conventional science law: sometimes media debunked) if designed. And importantly
all of this disruptive base idea is approved by WM and active research continues wold wide.
Some of advanced use currently are more often for labs and pharmaceutical(MetalMembranes+)
• Wide range of claims from mainstream academics to sidelined engineers/scientists, particularly
non-west related(China+). Often key for anomalous effect is by Use of:
✔1 Various types of metal/silicon nanowire, ✔2 Janus particle(nano sized, have duel hydrophilic
and hydrophobic side) used membrane, also to some extent Charged Nanofilter Membrane
types, ✔3 Nanocarbon/Carbon Nanotube/Inorganic Nanotube or electro-conductive polymer,
✔3 Mixing/doping/coating certain nano or fine metal element such as Silver/Copper/Zinc etc,
✔4 Metal membrane(some advanced tech can make pores down to nano or smaller size, with
through straight even hole with super high flux rates, can be made to suit extreme conditions). --
