    Membrane-attached biofilms for VOC wastewater treatment I: Novel in situ biofilm thickness measurement technique.

    , Biotechnol Bioeng, Vol: 47, Pages: 82-89, ISSN: 0006-3592

    This article reports a novel nondisruptive technique for measuring the thicknesses of membrane-attached biofilms in situ, using a single tube extractive membrane bioreactor (STEMB). The biodegradation of a toxic volatile organic compound (VOC) (1,2-dichloroethane [DCE]) by Xanthobacter autotrophicus GJ10 has been used as a model system to develop the technique. The results give information on the biomass-silicone rubber attachment phenomena, and on the development over time of biofilms growing on the silicone membrane, without disrupting operation. Experimental results are presented showing the evolution over time of biofilm thickness, and also the density of biofilms for four experimental runs. The hydrodynamic conditions on the biomedium side of the membrane were found to influence the initial attachment phenomena and subsequent biofilm growth. (c) 1995 John Wiley & Sons, Inc.

    Membrane-attached biofilms for VOC wastewater treatment. II: Effect of biofilm thickness on performance.

    , Biotechnol Bioeng, Vol: 47, Pages: 90-95, ISSN: 0006-3592

    This article reports a study of the performance of membrane-attached biofilms grown in a single tube extractive membrane bioreactor (STEMS) used for the treatment of a synthetic wastewater containing a toxic VOC (1,2-dichloroethane [DCE]). Mass balances show that complete mineralization of DCE was achieved, and that the biofilms were effective in reducing air stripping to negligible levels. Experimental results are presented showing the evolution over time of biofilm thickness and its influence on the flux of DCE across the membrane. It has been found that a trade-off exists between the positive influence of biofilms in reducing air-stripping of DCE, and the negative influence of biofilms in reducing DCE flux across the membrane. These considerations lead to an optimal biofilm thickness in the region of 200 to 400 mum being recommended for this system. (c) 1995 John Wiley & Sons, Inc.

    Minimizing the environmental impact of process Plants: A process systems methodology

    , Pages: 39-44, ISSN: 0098-1354

    A Methodology for Environmental Impact Minimization (MEIM) is presented in this paper. The methodology, which embeds Life Cycle Analysis principles within a process optimization framework, involves proper definition of a consistent boundary around the process of interest, identification of the emissions inventory, quantification of environmental impact via proper metries (for air and water pollution, solid waste, global warming and ozone depletion) and inclusion of environmental criteria within process modelling and optimization tools. A case study, the production of VCM from ethylene, is presented to illustrate the basic features of MEIM. © 1995.
