  • Compost Leachate Pond Bioremediation Case Study - Composting Facility, Northern California

    Our client runs a composting facility that receives green waste, food waste and other compostable material from residential and commercial sources, to create rich, black compost Challenge As part of the facility, the compost leachate pond has repeatedly experienced problems with the incoming influent high chemical oxygen demand (COD) and ...

  • Improving bioremediation

    Sustainability is becoming a benchmark for the quality of companies who offer remediation solutions, the technologies that they develop and offer commercially, as well as the entire projects where they are used. It is, in essence, not something that can be simply ignored in the months and years ahead if standards are to continue to improve, says Tom Hayes of Ecologia. The sustainability ...

  • A Citizen`s Guide to Bioremediation

    What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...

  • Field Demonstration of a Permeable Bioreactive Barrier for Leachate Control.

    ABSTRACT: A biostimulation technique was selected for a pilot study to treat groundwater at a former New Jersey municipal landfill. The process will address a mixture of chlorinated compounds (e.g. vinyl chloride and chlorobenzene), hydrocarbons (e.g. benzene and methyl ethyl ketone) and heavy metals. The reactive barrier will be constructed using a series of injection points to implace a slurry ...

  • SITE Technology Capsule - DARAMEND Bioremediation Technology

    GRACE Bioremediation Technologies’ DARAMENDTM Bioremediation Technology is an amendment-enhancedbioremediation technology for soils and sediments contaminated with a wide variety of organic contaminants includingchlorinated phenols, polynuclear aromatic hydrocarbons (PAHs) and petroleum hydrocarbons. The technology may be applied ex situ to sediment and soil and in situ to near-surface soils. The ...


  • Outstanding bioremediation in winter months case study

    Alga Power 101 was again able to prove its efficacy when it was utilized on a former industrial site in West Thurrock, Essex, under some extremely challenging conditions. Formerly a scrapyard, the contaminated site was heavily laden with diesel and other fuels. Prior to treatment the TPH of the soil ranged between 8,000mg/kg and 10,000mg/kg. Bioremediation took place between November and December ...

  • Bioremediation of diesel spill - cumbria, united kingdom

    Introduction Microbac has successful undertaken the clean up of a diesel spill at a site in Cumbria. The oil escaped from a large storage tank, located at the top of an incline after a problem occurred with closure of the valve. The position of the spill resulted in oil running down the incline and into the site drainage system. In response to the client"s request, Microbac ...

  • Ex Situ Biological Treatment for Groundwater, Surface Water, and Leachate

    The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the groundwater. However, ex situ treatment requires pumping of groundwater, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...

  • In Situ Biological Treatment for Ground Water, Surface Water, and Leachate

    The main advantage of in situ treatment is that it allows ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ treatment, however, generally requires longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

  • Common Treatment Technologies for Fuels in Ground Water, Surface Water, and Leachate

    It may be necessary to know other subsurface information to remediate fuels in ground water. Treatability testing to characterize contaminant biodegradability and nutrient content may be needed for any biodegradation technology. A subsurface geologic characterization would be particularly important to characterize the migration of NAPLs. Recovery tests are usually necessary to design a ...

  • Bioremediation of diesel oil - derwent island, national trust, united kingdom

    Introduction A spillage of red diesel oil (heating oil) from a holding tank located on Derwent Island in Lake Derwentwater, Cumbria, has been successfully treated using Microbac"s oil degrading bacterial cultures. The spill occurred in the Lake District National Park and a major concern was contamination of the lake water. The main problem associated with the work was access to the island ...

  • Semifield testing of a bioremediation tool for atrazine‐contaminated soils: Evaluating the efficacy on soil and aquatic compartments

    The present study evaluated the bioremediation efficacy of a cleanup tool for atrazine‐contaminated soils (Pseudomonas sp. ADP plus citrate [P. ADP + CIT]) at a semifield scale, combining chemical and ecotoxicological information. Three experiments representing worst‐case scenarios of atrazine contamination for soil, surface water (due to runoff), and groundwater (due to leaching) were performed ...

  • Performance study for anaerobic digestion of municipal solid waste in a single phase reactor

    Anaerobic Digestion (AD) has been up to now essentially applied to wastewater. However, anaerobic treatment of organic solid waste fits well with the new requirements for waste management. A batch study of vegetable market waste composed at various solid concentrations was studied in a single phase anaerobic reactor. Prior to this, studies were also carried out in aspirator bottles of different ...

  • Sequential extractions on mine tailings samples after and before bioassays: implications on the speciation of metals during microbial re-colonization

    Abstract  Mine tailings may be remediated using metal tolerant microorganisms as they may solve the limiting conditions for healthy development of plants (i.e., low organic mater content and poor physical conditions). The aim of this study was to investigate the consequences of microbial colonization on the chemical speciation of trace metals. Surface samples from the Valenciana mine ...


  • Case Study: Arjo Wiggins Factory Site, North Hykeham

    In January 2000, Blackwell were appointed as the main contractor for the remediation of an industrial site in Lincolnshire. The site was formerly used in the manufacture of thermal papers, had become contaminated with metalliferous mercy, zinc and asbestos. Site remediation was primarily driven by high ground water vulnerability. Following a comprehensive option study, volume reduction by Soils ...

  • Treating wastewater as a resource

    A number of UK landfill operators are turning wastewater into a resource by utilising OTT monitoring and control systems to manage the irrigation of Willow crops (for renewable energy generation) with pre-treated effluent. Background Leachate from landfill sites represents a significant potential environmental liability, extending long into the future after a landfill site has ...

  • Environmental Sensors in Waste Management

    Issue: As part of an increasing sentiment among European consumers that environmental protection is important, concern about the impact of landfill is growing. Sensor technology makes it possible to measure and control inputs to landfill sites and pollutants arising from them. However, the exploitation - or uptake - of such technology has been lower than expected in the waste management sector. ...


  • Biopiles

    Biopile treatment is a full-scale technology in which excavated soils are mixed with soil amendments and placed on a treatment area that includes leachate collection systems and some form of aeration. It is used to reduce concentrations of petroleum constituents in excavated soils through the use of biodegradation. Moisture, heat, nutrients, oxygen, and pH can be controlled to enhance ...

  • Vapor-Phase Biofilters Show Promise for Treating High VOC Emissions.

    Evaluating the Feasibility of Natural AttenuationUsing natural attenuation to remediate organic compounds in groundwater has gained popularity. In some cases, this process can reduce contaminant levels to below risk-based corrective action criteria or regulatory standards without implementing additional remedial action alternatives. However, it is often difficult to prove that natural ...
