Biological degradation of some organic compounds enrolled in paper industry

Evaluation of the elimination and the 'ultimate' biodegradation by aerobic microorganisms of some organic compounds applied in paper manufacturing tec hnology was investigated. Biodegradation lines of line organic compounds as percentage removal of chemical oxygen demand (COD) were detected over a se ven day incubation. The results of the biodegradability test clearly reveal ed that some of the organic compounds under investigation are highly biodeg radable, while others rank from fairly to even non-biodegradable. Significa nt biodegradation results were recorded as COD removal, for Anti-coating es ter (95.0%), Basoplast 200D (85.3%) and Basoplast FR 8050(87.6%). Bleaching agent (Formamidin-sulfinic acid), Ukanol BSA and Solidurit KM demonstrate moderate biodegradation results of 62.1%, 76.2% and 69.8%, respectively. Po or biodegradation results for Hedifix M/35 (12.7%), Basazol Orange (34.9%) and Basazol Brown (29.0%) were recorded. Accordingly, appropriate caution s hould be taken into consideration when applying these compounds.
