  • Decontamination showers for the pharmaceutical industry

    Removing contamination from Personal Protective Equipment (PPE) is part of the daily routine for many workers in the pharmaceutical industry. They shower when leaving laboratories, production or packing areas to prevent the escape of potentially harmful contaminants. In some instances, they may even shower before entering production areas to avoid contaminating vulnerable processes. Hughes has a ...

  • 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 ...

  • 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 ...
