  • Method and apparatus for separating suspended solids from liquids
    Patent number: 4743382
    Abstract: Liquid which has been partially clarified in the settling zone of a clarifier tank is channelled through a filtration compartment containing a buoyant particulate filtration media. The media particles are periodically agitated so that trapped solids are separated from the media and retained in the clarifier tank.

  • Methane production
    Patent number: 4571384
    Abstract: Methane is produced by dissolving mineral carbonate in water to produce dissolved carbon dioxide which is converted to methane by anaerobic methanogenic bacteria in the presence of hydrogen gas supplied to the water. Preferably, the mineral carbonate is in the form of a bed of particulate mineral carbonate with the bacteria attached thereto. The bed is submersed in the water in a closed vessel and a flow of hydrogen gas is passed through the vessel.

  • Gas chromatograph detector
    Patent number: 4541269
    Abstract: A gas chromatographic detector for detection of compounds which fluoresce as a photo-response to light. The detector utilizes a remotely located light source for fluorescent excitation of a compound in a gas phase, and includes apparatus for the measurement of emitted fluorescence of a gas and for the measurement of transmitted light through a gas. The detector is close-coupled to an output end of a heated chromatographic column and eliminates the requirement of heated transfer tubes between the column and the detector.
