| Abstract: | Evaluation of the elimination and the "ultimate" biodegradation by aerobic microorganisms of some organic compounds commonly used in paper manufacturing technology was investigated. Biodegradation lines of nine organic compounds were determined as percentage removal of chemical oxygen demand (COD) over 7 days incubation. The results of the biodegradability test clearly revealed that some of the organic compounds under investigation are highly biodegradable, while others rank from fairly to even non-biodegradable. Significant biodegradation results were recorded for anti-coating ester (95.0%), basoplast 200D (85.3%) and basoplast PR 8050 (87.6%). A bleaching agent (formamidin-sulfinic acid), ukanol BSA and solidurit KM demonstrate moderate biodegradation results of 62.1%, 76.2% and 69.8%, respectively. Poor biodegradation results for Hedifix M/35 (12.7%), basazol orange (34.9%) and basazol brown (29.0%) were recorded. Accordingly, appropriate precaution should be taken into consideration when using these compounds for industrial applications. |
