Quantitative study on biological TOC reduction in brine


Wir bitten um Verständnis, dass die Informationen über dieses Projekt derzeit nur in englischer Sprache verfügbar sind.


Project Content:

Effluent Brines as waste from another industrial process might be usable for the electrolysis of sodium chloride to produce chlorine, which is the most important electro–membrane process worldwide.  Since the electrolysis membrane is sensitive to contamination, undesired components from the brine should be removed before usage.

The waste brine may contain a high amount of organic carbon, Total Organic Carbon (TOC) which will damage the electrolysis membrane. Therefore, it is necessary to reduce the organic carbon content of the brine before the electro-membrane process. Although chemical treatment of brine is possible, it cannot reduce TOC to the acceptable limit. Hence, biological treatment of brine was recommended as an alternative method.

The aim of this project is to find an industrially applicable biological alternative to reduce the TOC content of brine. On one hand, the goal is to find strains which are able to consume glycerol as a carbon source in hypersaline environments. On the other hand, it is also necessary to quantitatively discover the bioprocesses, such as describing as well as quantifying the metabolism on glycerol and investigating the most determining process parameters.
Due to the hypersaline highly corrosive environment, a special bioreactor made out of glass- and suitable polymers was designed and is applied for the bioprocess development.
