The coalsi product series offers manifold street-channel filters used mainly for effective odour elimination in sewage water canals. The coalsi odour barrier – developed for sewage manholes – is the economic and efficient solution for the elimination of malodour. Besides, the side inlet filter was especially designed for side inlets. For the treatment of odourous gas emissions and for small manholes, multi-chamber filters are used.
All coalsi odour filters are hybrid activated carbon Effective odour retention of organic compounds is symptomatic for the hybrid technique. Fritzmeier quality management ensures that neither human, nor animal or plant pathogenic organisms can be detected. The odour filters are mainly used for communities and industry as well as in the domestic environment.
