Classic technology is often not able too efficiently remove UFP’s and therefore new techniques are necessary to keep your site running smoothly.
What are Ultra Fine Particles
Emission of fine dust or ultra-fine particles (UFP’s) are considered to be <0.1 μm or 100 nm in diameter. Maximum Allowable Concentrations (MAC values) for this size of ambient air pollution, is becoming more important for manufacturers every day.
UFP’s are both naturally occurring as manufactured. Natural causes can be Smog, Smoke or Fog. Manufactured UFP’s are often byproducts like emissions from production equipment, combustion reactions or other processes.
Fine Particles can be roughly divided into 5 categories:
- Vapor: A liquid substance suspended in air, much like fog
- Damp: A liquid substance that has changed phase through heating, such as steam.
- Fumes: An often noxious suspension of particles in a gas, such as exhaust fumes.
- Gas: A substance of matter that has changed to gaseous phase.
- Odor: A fume, a or vapor that has a strong smell.
Ultra-fine dust is usually formed when fumes become particles (nucleation). Fume dominated work environments, such as plastics, toner, and rubber production, adhesive spraying, and roofing production lines can have UFP concentrations up to some 20,000 particles per cm3. Other sources of UFPs are powder and particulate processing, such as impact milling in (animal) food, ingredients, chemicals, pigment, cosmetics, and pharmaceutical production.
Why is UFP Removal important for manufacturing processes
Harmful UFP’s require adequate elimination from the work area to guarantee a healthy work environment and increase explosion safety. It has become more and more evident that ultra-fine particulates have a direct negative effect on Operator health (leading to lung and heart failures). The EU is considering 40 µg/ m3 as the UFPs exposure limit, while the WHO recommends a 10 µg/m3 personal exposure limit.
UFP’s can be considered as one of the most dangerous particles due to their size, as this allows them to be breathed deep into ones lungs and easily reach ones bloodstream.
