Results and discussion
Any other information on results incl. tables
The results obtained showed that the sulphur containing malodorous compounds can be removed by anaerobic digestion system, combined with an alkaline scrubbing process of digester gas. It was shown that DMS could not be decomposed by thermophilic anaerobic fermentation.
Applicant's summary and conclusion
- Conclusions:
- DMS could not be removed biologically from kraft pulping wastewater by an anaerobic digester sludge.
- Executive summary:
Endo (1985) is a non-GLP-compliant, non-guideline study following scientific principles, investigating the capability and performance of anaerobic biological decomposition of malodorous compounds in kraft pulping drains. The results of the study are not considered relevant so the study has only been used as a supporting study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
