  • Hot Gas Decontamination

    Introduction: The process involves raising the temperature of the contaminated equipment or material to 260 °C (500 °F) for a specified period of time. The gas effluent from the material is treated in an afterburner system to destroy all volatilized contaminants. The method eliminates a waste that currently is stockpiled and requires disposal as a hazardous material. This method will permit ...

  • Decontaminating Groundwater Sampling Devices

    These studies are the second part of a two year project that examines decontaminating groundwater sampling devices. In the first year, the efficiency of various decontamination protocols was tested using small test pieces of materials that are commonly used in groundwater sampling devices. Those tests showed that a hot detergent wash and rinse followed by hot air drying (105°C) was the most ...

  • Chances for Bio-LNG

    Abstract An increasing effort is put into the utilization of organic waste streams in anaerobic digesters, producing useful products such as fertilizers and biogas. It becomes increasingly attractive to upgrade biogas to natural gas quality and consequently liquefy the gas to Bio-LNG. DMT Environmental Technology has been developing biogas treatment plants for over 25 years, closely ...

  • Pumping water to decontaminate a karstic spring

    After being struck by lightning, an underground military fuel tank lost all its contents. After a few hours, petrol mixed with foam began to flow out of the nearby Forame spring, situated about 400 m away and at a height of 7.0 m lower than the bottom of the tank. The spring feeds the Giavera stream which, after about 1000 m enters the upper Veneto plain, flowing into the irrigation network. ...

  • Decontamination of soil contaminated with petroleum grease

    Contamination modifies the engineering properties of soil, thereby restricting its further use either as a construction material or as a supporting medium. Due to the scarcity of land, it becomes imperative to reuse the land for infrastructure developmental activities. Out of numerous soil contaminants, automobile grease is one of the most prominent. Considering the cumulative impact of ...

  • Water decontamination by silver and copper montmorillonite

    Several bactericide inorganic materials have been used for the purification of water with varying success. The characterisation of the incorporation of Ag or Cu cations in montmorillonite (MMT) clay, to obtain a bactericide material against E. coli, indicated that both outer and interlayer surfaces act as adsorption sites of AgO and Ag2O or CuO, respectively. The Ag–exchanged ...

  • Enhanced Bio-Remediation of Wastewater

    Bioremediation has been used to treat hydrocarbon contamination in municipal wastewater for centuries. Most microbes used in bioremediation today are naturally occurringyetspecifically chosen and cultured versus being genetically modified. Bioremediation rivals techniques such as pump and treat extraction systems, as it provide cost savings for municipalities, as well as environmental savings by ...

  • Bio-fuels- Anaerobic digestion

    Anaerobic digestion is a series of processes in which micro organisms break down biodegradable material in the absence of oxygen. It is widely used to treat wastewater sludges and organic (agricultural) wastes.  As part of an integrated waste management system, anaerobic digestion reduces the emission of gas into the atmosphere. Anaerobic digestion is a renewable energy source because the ...

  • A Return On Investment with Bio-Augmentation

    Henderson, Louisiana is located directly in the center of what is commonly considered ‘Cajun Country.’ Right next door to Breaux Bridge, the town that is known as ‘The Crawfish Capital of the World’; our claim to fame is dealing with the crowds and traffic of that festival every spring. But, Henderson is just fine with that situation, just being the ‘bedroom ...

  • Marginal reasoning and (bio)diversity

    One of the decisive advantages of a systems approach is the possibility to achieve a level of efficiency beyond any individual effort by integrating diverse capabilities. Integrated diversity should therefore be regarded as the source for the potential development of any system. The wealth of any sustainable society depends thus not only on its factor endowments, but also on its capability to ...
