Membranbioreaktoren zur industriellen Abwasserreinigung
Membrane bioreactor (MBR) technology for treatment of organically contaminated wastewater is one of the notable developments in recent years. MBR technology is based on the ongoing development of biological water treatment with suspended biomass, where membranes are used to separate the …

Verfahrenskombination von Nanofiltration und Adsorption an Pulverkohle zur kontinuierlichen Abwasserreinigung
Highly contaminated waste waters (e.g. wastewater from textile dying processes or dumpsite leachate) have to be treated because of their high content of poorly biodegradable organics. A treatment process has to provide both a low cost sink for the organic contaminants and a near-complete removal of …

Phosphorrückgewinnung bei der Abwasserreinigung : Entwicklung eines Verfahrens zur Integration in kommunale Kläranlagen
Economically exploitable phosphate ore resources are finite and non-renewable. Due to the fact that phosphorus is, besides nitrogen, the main nutrient for plant growth, most of the phosphorus world-wide is used for the production of mineral fertilisers. Because of the increasing world population …

Cytostatics in the aquatic environment : analysis, occurrence, and possibilities for removal
Many pharmaceuticals have attracted the attention of environmental scientists and are of concern due to their observed occurrence in surface water, ground water, drinking water, sediment, and soil. Further investigations have considered their removal efficiencies in wastewater treatment processes …

Aufbereitung von Brauereiabwasser bis zur Wiederverwendbarkeit
The buffering and balancing basins of a brewery have been developed to an aerobic wastewater treatment plant. The procedures have been adapted on the demands of the further treatment. One- and two stage membrane-plants have been piloted, a cleaning concept has been developed and filtrates and …

Auswirkungen von Pulveraktivkohle auf die Nanofiltration von Kläranlagenablauf
Process combinations of powdered activated carbon adsorption and succeeding membrane process are currently under investigation for several different water treatment applications and a few full-scale applications of this kind of process already exist. Since the powdered activated carbon is usually …

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 …

Role of extracellular polymeric substances and metals in fouling of membranes in the wastewater treatment
The use of membrane bioreactors (MBRs) for wastewater treatment has been increasing since the 1990s and is gaining more importance due to rising demands for water in general. There is yet one main limitation in full-scale applications of MBRs: the membrane fouling, leading to a substantial loss of …
