  • Patent number: 11033837
    Abstract: A feedwell design for a clarifier that may better dissipate the entrance energy of feed slurry liquid exiting the feedwell and entering the clarifier. Plates having a surface area twisted around a longitudinal axis may be provided at the bottom of the feedwell. The plates may cause a change in the flow direction of the feed, from being mostly horizontal to mostly vertical, to slow the slurry. The provision of plates at the bottom of a feedwell in a clarifier may advantageously reduce the velocity of the materials entering the clarifier, or may increase the uniformity of the flow rate of the materials while reducing or maintaining the amount of shear force, turbulence, or other forces that may have a detrimental effect on clarification. Likewise, this may improve the rate at which solids settle out of the feed slurry solution, and thus improve the clarity of the removed liquid.

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: 8721889
    Abstract: The present invention provides a method for treating wastewater in which the majority of solids and biological oxygen demand compounds are separated from the wastewater feed using a primary separation process, to produce a solids phase and a water phase. The solids phase is irradiated to reduce the level of pathogens such that it is safe to use as a soil substitute and/or additive so that the solids can thus be disposed of in an environmentally-friendly manner. In additional embodiments, the solids that have been disinfected by radiation are mixed with a suitable inert filler material to produce a soil substitute, fertilizer, compost, or other soil additive. The liquid phase is treated in a substantially smaller system than would be required for treating the full-strength wastewater that can include a suspended media biological regeneration reactor system.

  • Patent number: 8709135
    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.
