  • Patent number: 7754080
    Abstract: A system for recycling drilling sludge is disclosed. The system has a treatment area and a salt-tolerant bio-reactor coupled to the treatment area. The bio-reactor has i) at least one bio-suspension element for supporting the growth of at least one type of biological microorganism within an enclosed flow zone; ii) an agitator for creating a flow of the drilling sludge through the enclosed flow zone at a flow rate; and iii) an aerator for providing a gas to the enclosed flow zone. The system also has a processor coupled to the agitator and configured to create at least a minimum self-cleaning drag force between drilling sludge passing through the enclosed flow zone and the combined at least one type of biological microorganism and the at least one bio-suspension element. A related method and bio-reactor are also disclosed.

  • Patent number: 7101483
    Abstract: A process for treating a body of water in which a bioreactor and a water eductor are located in a body of water such that the eductor is submerged beneath the body of water to a depth of at least about 3 feet. The water eductor produces a water flow at a rate of at least about 60 feet per minute; the water flow is substantially parallel to the surface of the body of water. Water is also passed through a bioreactor that contains a plurality of bio-suspension elements within an enclosure located above a screen in the enclosure.
