11.2 Filter plants
Filter plants are used for dedusting of the dust in the air generated e.g. by blasting. They are subject to many legal provisions and directives like for instance the German technical directive on air quality control (TA-Air), an administrative provision regarding the Law concerning the protection against harmful effects on the environment through air pollution, noise, vibrations and similar factors.
