Particles of roughly 0.1–1m diameter are carried by the gas
streamline sufficiently close to the surface of the droplet that the
particle touches the droplet [18]. These particles have insufficient
inertia to leave the gas streamline and are carried with the streamline.
Some gas will flow very close to the particle. This mechanism
known as interception is a relatively weak mechanism for particle
collection compared to impaction [18]. It is coincidental that
the path of the streamline and the particle happens to be close to
the droplet. It is for this reason that particles in this size range are
difficult to collect compared to larger and smaller particles.
As indicated in Fig. 3 the removal efficiency for PVC particles
larger than 2m becomes approximately 100% while employing
100 l/h water. This results show the very good performance of this
scrubber.
