Actual situationAir pollution due to industry:
PM10 – indicator for evaluation of acute impact on healthPM2,5 – indicator for evaluation of long-term impact on health
– Increase in per year concentration of PM2,5 by 10μg/m3:– Increase in death ratio by o 1,5%– Increase in bronchitis occurrence by 34%
Small grained PM2,5 differ in both origin and composition from biggergrained particles :
– Combustion of fossil fuel (coal power plants, incineration plants )– Traffic (diesel engines)– Secondary aerosol (Gas condensation)

Actual situation
Dust of PM2,5 particles: – carbon substances, salts, heavy metals – very light, remains in atmosphere for weeks – cause of grave illness
Gas-based pollutants: SO2, NOX, PCDD/F, VOC
How to prevent polution? Solution:1. Emission – Most efficient filtering in industry possible, which will eliminate air pollution (coal power plants, stealworks,)2. Imission – preventing the polution allready dispersed in air from intruding to areas where is great concentration of people every day – Most efficient filtering of atmosperic air possible in HVAC (offices, shop shopping centres, public buildings,...)

NANOSOLUTION
Our nanosoluotions allow most efficient filtering of solid particulate
matter combined with simultaneous reduction in concentration of gas
based pollutants (NOX, VOC, PCDD/F).

NANOSOLUTIONNanosolutions sorting:
1. Filters for atmospheric air

(HVAC, gas turbines,…)
2. Filters for industrial
use BAG FILTER
(coal power plants, stealworks,
cement works, incinerator

BAG FILTERS• Substances most harmfull to atmosphere:• Small grained PM2,5 • NOX, SO2, VOC, PCDD/F• For solid particulate matter (spm for short) separation are usually used:
– Mechanical separators (very unefficient even for PM10)– Electrical separators (sufficient for PM10, but not very effective for PM2,5)– Textile filters (PTFE membrane – which is most efficient technology available)
Future:• Nano layer textile ( it is approximately one order of magnitude more effective than PTFE)

FILTERS REGENERATED BY COMPRESSED AIR
Suitable for sticky dust, can be used in old systems with verticaly organized cylindric tubes or horizontaly organized ovals, higher cost for compressed air.

FILTERS WITH FAN FLUSH
Regeneration with medium pressure fan is
thrifty for filtration material. Less costsly.

horizontaly organized pockets.

BAG FILTERS
WHY USE NANOFIBRES?
Bag filters using the Nanofibres having all the best
factors together:
• Permeability (small pressure drop)• The best filtering efficiency• Very small thickness of the layer• High porosity• Low basis weight not increase filter media weight• Small pore size• High specific surface area• Submicron particles capture

BAG FILTERS – PTFE MEMBRANE
Comparison of nowadays best technology (PTFE membrane) with a vision of future sollution (PTFE nanofibers):
PTFE micorfibers fused together at intersection points. These hydrophobic membranes provide ultimate chemical resistance and are temperature stable to 250 °C.
PTFE nanofibers will have similar chemical and heat abilities but lower pressure loss and smaller needs for regeneration system (saving energy), higher filtration efficiency (catalyst lasts longer).
For industry with lower heat and chemical stress the nanolayer can be made of cheaper materials (Nomex, Polyimid, Polyester).
