| 20090159461 | ELECTROHYDRAULIC AND SHEAR CAVITATION RADIAL COUNTERFLOW LIQUID PROCESSOR - Axially fed fluid is sheared during long residence time in a radial workspace between counter-rotating coaxial disk-shaped centrifugal impellers. Gases evolve in the fractal turbulence of a shear layer, which is forced between laminar boundary layers, and an axial suction pump axially extracts evolved noncondensibles and volatiles through cores of radial vortices in the shear layer. Cavitation due to shear between the impellers kills pathogens by shock waves, microjets, OH radicals, and nearby UV light pulses. Oppositely charged electrodes bounding the workspace cause electroporesis and electrohydraulic cavitation. The electrodes are counter-rotating ridged armatures of disk dynamos, forming a dynamic capacitor having audio frequency pulsed electric fields. Electrode erosion by arcing is prevented by shear between the electrodes. | 06-25-2009 |

| 20100140107 | Treatment for produced and flowback waters from wells - Produced and flowback fluids, and other fluids emanating from oil, mining, and mineral extraction operations, are treated to remove heavy metals by introducing an oxidizing agent and passing the fluid through an electrocoagulator.

| 20100187130 | Coagulants made in situ from sulfate-containing water and uses therewith - Acid mine drainage and surface waters containing sulfate are processed by an electrocoagulator to make aluminum or other polyvalent metal sulfate, which acts as a coagulant for solids suspended in the waters. The process thus removes and puts to good use highly undesirable sulfate anions, obviating combinations with barium and other scale forming metals when the fluids are used in well drilling for other purposes associated with hydrocarbon recovery. Well fluids may be treated with the acid mine drainage including the sulfate coagulant made in it. Efficiency of the process may be enhanced by the addition of an oxidizing agent and/or by passing the fluid through a cavitation device or other mechanism to improve mixing, enabling the process to handle large quantities of acid mine drainage and fluids handled in hydrocarbon recovery, particularly from shale formations. | 07-29-2010 |

| 20120152761 | SELENIUM SEPARATION AND RECOVERY FROM BIOREACTOR SLUDGE - Wastewater containing soluble selenium is treated in a bioreactor. Microorganisms in the reactor reduce the selenium to elemental selenium, which is insoluble. The elemental selenium is discharged from the reactor in waste sludge. The sludge is treated to recover selenium. In one method, the sludge is washed with chemicals, for example surfactants, and agitated to disrupt the adhesion of the selenium particles to the cells. The selenium particles are then separated from the cells using a physical separation process such as a centrifuge or differential filtration. In another method, the sludge is de-watered or dried to a very high solids content. The selenium particles are dissolved using an oxidizer under high pH conditions. A solids fraction is removed from the resulting slurry. A resulting selenium brine is further refined to recover the selenium. | 06-21-2012 |
