  • Proof That Bacteria Degrade Oil

    There has been a lot of publicity and ‘noise’ around the ability of bacteria to degrade oil, especially following BP’s Gulf of Mexico incident.  However little has been shown to prove that biological remediation is an effective means of treating oil contamination. Over many years CBIO have worked to develop a range of a microbial products that have proven to be able to ...

  • Mechanical biological treatment trends

    Composting mixed municipal solid waste has a long tradition in Germany. In 1953, the first large-scale facilities in Baden-Baden and Blaubeuren started operating, followed later by plants in Heidelberg, Duisburg and other locations across the western part of Germany. Facilities were being opened to provide alternatives to landfilling MSW, and to produce compost for agricultural use. The quality ...

  • Biological Treatment Technologies

    Decontamination companies and researchers in France are working to restore polluted soil using treatments that range from biological methods to soil washing and incineration. The problem of polluted soil was dramatically illustrated prior to construction of the Stade de France soccer stadium built for the 1998 World Cup. The location of the site, on industrial wasteland just north of Paris, ...

  • The biological basis of wastewater treatment

    Introduction This booklet was written to fulfil the need for a simple explanation of the biological processes that underpin wastewater treatment. It attempts to show how the bacteria involved deal with the organic carbon in the sewage. Remarkably, there are just 3 major processes involved, and these mirror exactly the 3 major processes at work in the plant viz: biodegradation, oxygen ...

  • Life cycle assessment of the mechanical biological pretreatment of residual wastes

    In Germany the handling of wastes is regulated by the 'Kreislaufwirtschaftsgesetz (i.e. Closed Cycle Economy and Waste Act) which gives priority to waste avoidance. Waste that cannot be avoided has to be recycled or reused as long as it is environmentally favourable. The residual wastes have to be pre-treated before landfill to reduce the negative effects of the landfill as production of landfill ...

  • Unpleasant Odors Successfully Removed Using Biological Waste Water Treatment

    System designed by Dresden DAS Environmental Expert successfully treats landfill leachate from hazardous waste landfill in Grumbach, Germany DAS Environmental Expert has designed a system for the treatment of landfill leachate that currently treats the wastewaters of the AMAND Umwelttechnik Grumbach ...

  • Anaerobic digestion as integrated part of a mechanical-biological Waste treatment process

    Anaerobic digestion as a means of stabilising residual municipal solid waste (RMSW) before landfilling was evaluated to study the stabilization of RMSW through mechanical-biological processes and evaluate the effect on landfills. The tests were at the site of WGV Recycling GmbH in Quarzbichl between September 1995 and March 1996. The trials, which were run with a single-phase anaerobic digester, ...

  • Biological Odour Control for wheelie bins

    One of the problems with large wheelie bins used for waste storage is that organic deposits build up and these give rise to bad odours. From time to time the bins are washed to remove the organic deposits. However in many cases the odours are not removed so the bin may look clean but not smell clean. There are a number of different types of systems used to wash the bins and BioFuture have worked ...

  • Decomposition of major organic components during mechanical-biological pretreatment of residual municipal solid waste

    Landfilling of untreated municipal solid waste (MSW) generates environmentally hazardous gas and leachate emissions (El-Fadel et al., 1997). The aim of mechanical-biological waste pretreatment (MBP) is to anticipate this process in a controlled system and to avoid later emissions in the landfill (Leikam and Stegmann, 1997). Main source of these emissions is the microbial metabolism of the easily ...

  • Industrial Anaerobic Biological Fermentation - Case Study

    The cooperation between the above mentioned innovative companies forces to impressive results. Hager & Elsässer planned the Aquatyx R2S reactor-technology which is installed in glass lined steel tanks from GLS Tanks International. AQUATYX is primarily for industrial anaerobic biological fermentation of highly polluted wastewater, as they are to also found for example in the paper ...

  • Critical Role of Aerobic Uptake in Biological Phosphorus Removal

    ABSTRACTThe use of biological phosphorus removal (BPR) to remove phosphorus (P) from municipal wastewaters is well-established, and especially in recent years, there has been a significant increase in the number of utilities practicing BPR. The basic BPR mechanism includes two distinct steps: anaerobic P release, and aerobic P uptake. However, BPR design and optimization efforts have typically ...

  • Production and recovery of poly-β-hydroxybutyrate from whey degradation by azotobacter

    Poly-β hydroxyl-butyrate, (PHB) is a biodegradable thermoplastic which can be extracted from a wide range of bacteria. PHB belongs to the class of bacterial polyesters collectively called polyhydroxyalkanoates, (PHAs). PHAs have properties similar to polypropylene and are important due to their complete biodegradability, with recognised potential applications in reducing disposable waste ...

  • Ex Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of ex situ treatment is that it generally requires shorter time periods than in situ treatment, and there is more certainty about the uniformity of treatment because of the ability to homogenize, screen, and continuously mix the soil. However, ex situ treatment requires excavation of soils, leading to increased costs and engineering for equipment, possible permitting, and ...

  • In Situ Biological Treatment for Soil, Sediment, and Sludge

    The main advantage of in situ treatment is that it allows soil to be treated without being excavated and transported, resulting in potentially significant cost savings. However, in situ treatment generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in soil and aquifer characteristics and because the efficacy of the ...

  • Using On-Site Biological Methods to Clean Up Soil

    Decontamination companies and researchers in France are working to restore polluted soil using treatments that range from biological methods to soil washing and incineration. The problem of polluted soil was dramatically illustrated prior to construction of the Stade de France soccer stadium built for the 1998 World Cup.

  • Microbe Edition: Biological Nutrient Removal How In-Pipe Technology Works

    Biological Nutrient Removal (BNR) is critical for tie preservation of our lakes and streams. Large amounts of waste products are passed through our sewage treatment systems on a continuous basis. Nutrient loads discharged from these systems must be reduced to avoid eutrophication of the receiving waters. Microbes are aarticularly useful in biodegrading most of the com sounds treated by wastewater ...

  • Composting of municipal waste in Poland

    Composting constitute an important element of the integrated systems of municipal waste management, which is being developed these days. In such systems, the process is employed mainly in the treatment of selectively collected biologically degradable moist waste coming from kitchens, gardening and municipal green places. The biological treatment of mixed municipal waste, however, is employed ...

  • Pilot Project: Acclimated cultures of freshwater archaea and bacteria degrade synthetic sewage in a salt-water environment

    Introduction Freshwater is a limited resource in many geographical regions of the Earth. This may be the case in some areas that are very populous of aircrafts and sailing vessels, that require treatment of their wastes. This study was done as a way to investigate methods that may require less usage of the available freshwater in these areas due to wastewater treatment, if 1) archaea ...
