PRIMARY POLLUTANTS
• Power supply utilities and smelters have
been the only major sources of primary
particulate pollutants in Australia.
• Here an old picture of a
coal-fired power station at
Wallerwang, NSW.  It
illustrates the mess they
can make without emission
reduction technology.
• Particulate matter is
readily collected in
baghouses which pass the flue-gases thru fabric bags which are then shaken out.
