  • ASTM C1760 - 12 Standard Test Method for Bulk Electrical Conductivity of Hardened Concrete

    This test method measures the bulk electrical conductivity of concrete, which has a theoretical relationship to the diffusion coefficient of chloride ion, or other ions, in the concrete (1, 2). Experimental data confirm that there is a correlation between the apparent chloride diffusion coefficient measured by Test Method C1556, or similar method, and the bulk electrical ...

  • Recovery of Precious Metal Catalysts with Supercritical Water Oxidation

    Incineration is the traditional method used to recover precious metals from spent catalysts, but it has a number of drawbacks, particularly from an environmental point of view. Now a British-Swedish joint venture, involving Chematur Engineering AB and Johnson Matthey, has developed a process that uses supercritical water oxidation to recover the precious metals. The technology, called ...

  • Supercritical water oxidation of sewage sludge

    ABSTRACT Supercritical water oxidation (SCWO) is an innovative and effective destruction method for organic wastewater and sludge. Several tests of the destruction of sewage sludge by SCWO have been done at two state of the art pilot plants. These units have capacities of 250 kg/h and 1100 kg/h, respectively. The test results show that the technology easily destroys the organic ...

  • Treatment of Different Wastes by Supercritical Water Oxidation

    Abstract If left to conventional treatment processes, the destruction of toxic organic wastewaters and associated sludge volume reduction clearly becomes an overwhelming problem. Two options, incineration and supercritical water oxidation (SCWO), exist for the complete destruction of toxic wastewaters and organic sludges. Incineration has associated problems such as very high cost and ...
