Reinigung monomerbelasteter Abwaesser aus der Kautschukproduktion Schlussbericht

The latex production facilities of BUNA GMBH/Schkopau, East Germany, produce waste water burdened with monomers and solids. This project, carried out as a joint venture of BUNA GMBH and the Chemical Engineering Department of RWTH Aachen and funded by the BMFT, is to provide the basis for a suitable water treatment process. Various processes, i.e. reverse osmosis, ultrafiltration and microfiltration, monomer evaporation and adsorption on activated carbon, were investigated with a view to their applicability and economic efficiency. The various process stages will be combined in different ways. (orig./SR)Bei der Latexproduktion der BUNA GMBH/Schkopau faellt monomer- und feststoffbelastetes Abwasser an. In einer Zusammenarbeit zwischen der BUNA GMBH und dem Institut fuer Verfahrenstechnik der RWTA Achen sollen im Rahmen dieses vom BMFT gefoerderten Projektes die verfahrenstechnischen Grundlagen fuer ein entsprechendes Aufbereitungsverfahren geschaffen werden. Zur Abwasseraufbereitung werden die Verfahrensstufen Umkehrosmose, Ultra- oder Mikrofiltration, Verdampfung und Adsorption der Monomere an Aktivkohle auf ihre Anwendbarkeit und Wirtschaftlichkeit hin untersucht. Die einzelnen Aufbereitungsschritte sollen in unterschiedlicher Verschaltung zur Anwendung kommen.

Reinigung monomerbelasteter Abwaesser aus der Kautschukproduktion Schlussbericht

In order to clean monomer loaded waste waters of rubber production there were investigated three modifications of processing. In laboratory-scale there were obtained experimental results to coagulation, evaporation, micro-/ultrafiltration and reversal osmosis. These data were the basis of the lay-out of equipments and the selection of suitable membranes. First economical investigations showed, that the modification of processing by using membrane processes is favourable compared to the evaporation process. The check and improvement of the results in pilot-plant-stage had been prepared by work out of the duty specification and procurement of the equipment. The use of the results is considered to be realised in a manufacturing plant of the BUNA AGAvailable from TIB Hannover: D.DT.F.QN1(8,9) / FIZ - Fachinformationszzentrum Karlsruhe / TIB - Technische InformationsbibliothekSIGLEBundesministerium fuer Forschung und Technologie (BMFT), Bonn (Germany)DEGerman
