  • Patent number: 8702297
    Abstract: Methods and systems for chemical management. In one embodiment, a blender is coupled to a processing system and configured to supply an appropriate solution or solutions to the system. Solutions provided by the blender are then reclaimed from the system and subsequently reintroduced for reuse. The blender may be operated to control the concentrations of various constituents in the solution prior to the solution being reintroduced to the system for reuse. Some chemicals introduced to the system may be temperature controlled. A back end vacuum pump subsystem separates gases from liquids as part of a waste management system.
    Type: Grant

  • Patent number: 8191397
    Abstract: The present invention provides methods for checking and calibrating one or more concentration sensors in an open or closed system. More specifically, in one embodiment of the present invention, the disclosed method allows for the checking and calibration of one or more concentration sensors in which removal of the liquid from the system is required. In two additional embodiments, the disclosed methods allow for the checking and calibration of one or more concentration sensors without having to remove the liquid from the closed system thereby minimizing contamination of the system while at the same time greatly reducing or eliminating contact of the user with the liquid.
