Description: Das Projekt "Neuartige transversale Fliessmembran-Bioreaktoren zum Schutz der Umwelt vor schwer behandelbaren Risikoabfaellen" wird vom Umweltbundesamt gefördert und von Wehrle-Werk AG durchgeführt. General Information: Industrial process-water and waste water frequently contain 'persistent' organic compounds, some of which are toxic. These compounds are not biodegradable in conventional waste water treatment systems. It had even been assumed for a long time that such compounds were not biodegradable at all. However, in recent years it has been demonstrated in experiments on laboratory scale that many persistent compounds can be degraded by the application of specialised micro-organisms obtained under selective pressure. The project proposed is aimed at improving this new biotechnological concept focused on the leather and related industries.The objective of the project is to develop a membrane bioreactor (MBR) system in which biomass separation is carried out with a novel type of membrane module, the so-called transversal flow membrane module with micro/ultrafiltration hollow fibres. Advantage of this module over the existing module configurations (often tubular), is the low energy consumption due to the flow velocity which can be applied. The fibres which are located perpendicular to the flow direction act as a kind of turbulence promoters. Therefore the flow velocity can be decreased substantially to realise a similar mass transfer. Moreover, the aeration of the MBR takes also place by a hollow fibre membrane system, creating an improved oxygen transfer, especially at high biomass concentrations (up to 60 kg dry weight/m3). This entirely novel type of MBR system will have the following main advantages:u degrades persistent hazardous (toxic) compounds to an allowed level u makes more than 95 Prozent of the water suitable for reuse. U improves membrane filtration performance by significantly reducing both energy costs (5 times) and investment costs (flux enhancement). U has an almost zero-sludge production. The consortium will establish a research co-operation between TNO in the Netherlands and BLC in Great-Britain and will include a supplier of MBR systems, a technology transfer company and four end-users in the leather and textile industry. The successful completion of this project will result in an economical and environmental benefit for the leather, textile and all related industries all over Europe, improving their position compared to these industries outside Europe.
