  • Apparatuses for determining whether a substance is carried in a fluid
    Patent number: 9470681
    Abstract: Apparatuses for determining whether a substance is carried in a fluid are disclosed. One such apparatus includes a body having: a plurality of spaced-apart capture surfaces configured to contact the fluid and capture the substance from the fluid; and a plurality of fluid guiding surfaces spaced apart by a predetermined distance from respective at least portions of respective ones of the plurality of capture surfaces. Another such apparatus includes: a fluid conduit to direct flow of the fluid; and at least one element removably positioned in the fluid conduit and having at least one capture surface configured to contact the fluid and capture the substance from the fluid.

  • Method For Stabilization Of Biological Cultures To Allow Biological Treatment Of Brines
    Publication number: 20070275450
    Abstract: A process is disclosed for the biological treatment under anaerobic/anoxic conditions for the degradation of pollutants present in brine solution used in waste water management, in industrial waste brine solutions and in waste oil field brine solutions, especially waste brine solutions contaminated with perchlorate and nitrate. A culture capable of reducing perchlorate and nitrate in spent ion-exchange regenerant brine containing at least 30 g/L NaCl under anaerobic/anoxic conditions was used to demonstrate the process. A stabilized brine solution is also disclosed in which a culture capable of degrading a given pollutant can be proliferate.
