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.

    Abstract: An off gas extraction system cleans common sources of off gas, such as storage tanks and polluted soils. Off gas is extracted, followed by compression and condensation. Compression and condensation produce an off gas that can be reintroduced as a treated gas into the off gas source. Alternatively, a regenerative absorber cleans the treated gas by adsorbing residual chemical vapor and concentrates the removed chemical vapors and reprocesses them. If the treated gas is not reintroduced into the off gas source, conventional scrubbers may used on the back end of the system to produce a final exhaust as prescribed by environmental regulation. Methods of accomplishing the same are similarly provided, including novel methods for degassing storage tanks and treating polluted soils to meet current environmental regulations, as well as green technology and sustainability initiatives.

  • Patent number: 8653442
    Abstract: The invention provides a method, apparatus and system for separating cellular components, and can be combined with holographic optical trapping manipulation or other forms of optical tweezing. One exemplary method includes providing a first flow having a plurality of components; providing a second flow; contacting the first flow with the second flow to provide a first separation region; and differentially sedimenting a first cellular component of the plurality of components into the second flow while concurrently maintaining a second cellular component of the plurality of components in the first flow. The second flow having the first cellular component is then differentially removed from the first flow having the second cellular component. Holographic optical traps may also be utilized in conjunction with the various flows to move selected components from one flow to another, as part of or in addition to a separation stage.

  • Publication number: 20130327724
    Abstract: A system and method for filtering sediment from water prior to disposal. According to some aspects, water is provided to a trough which feeds a settling pool via a port. The settling pool may comprise one or more blocks disposed in one or more corresponding channels which restricts flow of the water. In some embodiments, this restriction of flow may cause sediment to collect on a bottom of the settling pool and/or residual oil to collect on a surface of the water. The residual oil may be pumped or skimmed from the surface and the water may be pumped from the settling pool into one or more external holding tanks The one or more blocks may then be removed from the settling pool and the sediment may be collected via a frontloader or other device accessing the sediment via an access ramp formed in the settling pool.
