PARTICULATE-EMISSIONS WITHIN FOUNDRIES - DUST ARRESTMENT REQUIREMENTS

Local exhaust ventilation, together with a means of arrestment and dis posal of airborne particulates, provides the basis of the vast majorit y of dust control solutions in foundries and a multitude of other indu stries. The paper concentrates on dry bag filtration, and demonstrates how a basically simple and very economical form of dust and fume cont rol can be applied to more arduous conditions to improve the working e nvironment within foundries, as well as reducing emissions to the atmo sphere, within the scope of current and anticipated legislation.
