Steuerung der Bioverfügbarkeit von Chloraromaten durch Tensid-modifizierte Tonminerale : Sorption und biologischer Abbau
To evaluate the influence of surfactant-modified clays (organoclays) on bioavailability and biodegradation of chloroaromates detailed knowledge of the sorption behaviour of these compounds is an essential precondition. Thus the sorption behaviour of 2,4-dichlorophenol (DCP) and monochlorobenzene …

Das Betriebs- und Alterungsverhalten biologisch schnell abbaubarer Hydrauliköle
The knowledge of the operation and ageing behaviour of ecologically acceptable hydraulic fluids is a prerequisite for successful applications of these fluids in hydraulic systems, in particular in the area of mobile hydraulic with its high power density. This thesis presents extensive …

Comparison of the biodegradation of pharmaceuticals and biocides in water and soil systems
The fate of organic chemicals in the environment is determined by both abiotic and biological processes and microbial degradation of chemicals is a key parameter for their environmental risk assessment. The majority of chemicals have been tested for ready biodegradability in aqueous systems (e.g. …

Bioaugmentation zur Eliminierung abgeschiedener Abfallfettfrachten aus Gastronomieabwässern
Lipids (fat, oil and grease) cause disturbances in both public sewer pipes and wastewater treatment plants. The pretreatment of sewages with high lipid loads is absolutely important in order to prevent damages. Bioaugmentation technology, i.e. the use of microorganisms, turned out to be a means to …
