  • Hepa this Hepa that, is there such thing as a true Hepa vacuum?

    We all see it, the big Hepa sticker on the side so we automatically believe the vacuum must be a Hepa rated vacuum, right? - Sorry the chances are the Vacuum would never pass a Certified D.O.P test. Just because a vacuum has a Hepa filter doesn't make it a Hepa vacuum, many factors have to be taken into account such as: The Hepa Filter needs to be sized according to the airflow ...

  • Ignition: A Century of Research and an Assessment of Our Current Status

    Ignition has been systematically, scientifically studied for about a century now. But the development of knowledge in this area has been uneven, and while an advanced understanding has been reached in some areas, knowledge is scant in others. A review of the literature of the field indicates that the following are some of the notable areas where engineering calculation methods are poor or ...

  • Biofilter Applications in the Coatings Industry.

    Soaring energy costs and the high cost of ‘end-of-pipe’ pollution control equipment has caused companies and regulatory agencies to re-evaluate ‘unconventional’ means of achieving VOC and HAP emissions control. The coatings industry is an excellent candidate for alternative, unconventional controls, as VOC and HAP reductions have not been as strident as has been the case in many other industries. ...
