  • Patent number: 9427706
    Abstract: Overburden from surface coal mining in many regions can produce a rain runoff laden with selenium, in the selenate form. This occurs from rainwater leaching through exposed selenium-containing rocks in the overburden. The selenium-containing runoff water is caught in ponds. Remediation of the pond water to remove selenate is performed by treatment with sulfur-modified iron (SMI) in a contact bed of an upflow reactor vessel. The pond water after pretreatment is pumped through the SMI reactor, and can then be run through an oxidation tank and filtered to remove iron. For extending effectiveness and life of the SMI the contact bed is either periodically “fluffed” with a high-velocity upflow of water through the bed, or moved continuously through the column in a continuous medium filtration system. A biocide can be added to runoff water prior to the contact bed.

  • Patent number: 9139483
    Abstract: Hydrophobic contaminants are removed from sludge that has been liquidized by violent shearing, by stirring a hydrophobic sorbent substance material into the sludge. After a period of time in which the contaminants are sorbed into the sorbent, the sorbent substance is separated from the sludge by gravity-settling, centrifuging, etc, where the sorbent is a liquid, or by filtration etc where the sorbent is a solid. Some sorbents have a melting point such that the sorbent can be liquid for good dispersal in heated sludge, and then can be solid when the sludge has cooled, whereby the sorbent can be removed e.g by filtration. Liquefaction by violent shearing causes the biosolids in the sludge to go into solution, which leaves the hydrophobic contaminants more available to be sorbed.

  • Patent number: 8790514
    Abstract: Systems and methods have been developed for reclaiming water contaminated with the expected range of contaminants typically associated with produced water, including water contaminated with slick water, methanol and boron. The system includes anaerobically digesting the contaminated water, followed by aerating the water to enhance biological digestion. After aeration, the water is separated using a flotation operation that effectively removes the spent friction reducing agents and allows the treated water to be reclaimed and reused as fracturing water, even though it retains levels of contaminants, including boron and methanol, that would prevent its discharge to the environment under existing standards. The treated water may further be treated by removing the methanol via biological digestion in a bioreactor, separating a majority of the contaminants from the water by reverse osmosis and removing the boron that passes through the reverse osmosis system with a boron-removing ion exchange resin.

  • Patent number: 8308944
    Abstract: A wastewater treatment method includes the steps of supplying a wastewater influent having nutrients for a population of phototactic heterotrophic microorganisms to an aerated bioreactor. At least a portion of the nutrients is converted into the phototactic heterotrophic microorganism population. The wastewater influent and the phototactic heterotrophic microorganism population together form a bioreactor effluent that is transferred to a light clarifier. The bioreactor effluent is concentrated in the light clarifier to form a low-solids effluent and a high-solids effluent. The concentration is performed by inducing the population of phototactic heterotrophic microorganisms to phototactically self concentrate through exposure to a light having at least one of an intensity and a wavelength sufficient to cause the phototactic heterotrophic microorganism population to migrate away from a source of the light. The high-solids effluent is then dewatered to form a concentrated biomass paste.

  • Patent number: 8052873
    Abstract: A waste treatment method includes the concentration of selected strains of bacteria in a selected medium in the presence of nutrients and water, under aerobic conditions. This concentrated batch is thereafter discharged for downstream applications in wastewater remediation. The present invention employs a cultivation chamber having inlet ports and a circular vent port that allows for adequate air introduction and heat release. Aeration is achieved by recirculation of the fluid medium from the top of the apparatus through a pipe that runs the length of the inner wall and is specially configured at the top to minimize cell damage. Fluid can be routed tangentially in both the clockwise and counterclockwise directions within the chamber. The conical bottom also has an orifice allowing for recirculation of the fluid medium tangentially to the sidewalls.
