  • Patent number: 7767097
    Abstract: Water from coal bed methane production which is suitable for almost nothing, is ozonated in a reactor to oxidize the iron content from +2 to +3, that is from ferrous to ferric, and to oxidize the manganese content from +2 to +4. The water after such first treatment is run through a separation means and then through a rotating filter, and then subjected to capacitive deionization, to yield clean water, which is then treated further to adjust he sodium content to render the water suitable for domestic and agricultural purposes. Some of the produced water is run back through the capacitive deionization cells when no voltage is applied to clean the cells for the next voltage application cycle. Some of the water produced may also be run back through the separation means to help clean out the crud.

In use, ammonia present in the effluent is converted to nitrate in the presence of the oxygen admitted by the air vent in the first chamber. The liquid retained upstream of the berm and above the liner undergoes anaerobic reactions. The remaining liquid proceeds to a place in the second chamber from which the drainage pipe can be entered, from which the treated wastewater can enter the soil.

  • Patent number: 7544298
    Abstract: A dispensing apparatus and method for the inoculation of a bioremediation agent into a waste stream, including but not limited to sludge or oil. The apparatus is capable of generating and maintaining a continuous release of decomposing bacteria, and living organisms, into a septic tank of sewage treatment system each time a toilet is flushed, or a boat bilge is pumped. The dispensing apparatus and method also provides a solid or liquid inoculate introduced directly into the apparatus for release into the waste stream slowly and continuously over time.

  • Patent number: 7544287
    Abstract: A bioreactor vessel has a biological support provided within the vessel to support bacteria and a drive system for agitating the biological support while it is it is immersed in the reaction liquor that is to be treated within the vessel. The drive system causes the biological support to oscillate with a reciprocating or rectilinear motion and the drive system is preferably located either outside the vessel or within a portion of the vessel that is above the level of reaction liquor present therein.

  • Patent number: 7534351
    Abstract: There is provided a reaction system capable of, in the feeding of liquid stored after gas-liquid mixing into waste water to be treated of a reaction tank, conditioning the interior of the reaction tank to a pressurized state so as to simultaneously accomplish enhancement of utilization efficiency of gas phase and further reduction of the amount of excess sludge generated. There is further provided a biological purification process characterized in that microorganisms fulfill purification activity in a pressurized reaction tank having a pressure other than deep water pressure applied thereto. Preferably, together with water to be treated, reactant gas such as pure oxygen, ozone-containing oxygen (ozonized oxygen) or air is fed into the pressurized reaction tank. With respect to gas and liquid fed into the reaction tank, preferably, reactant gas is fed in the form of dissolved gas or microbubbles by means of a gas-liquid mixing unit (line atomizer).

  • Patent number: 7524419
    Abstract: A system for wastewater treatment comprises a tank and includes a mixer that generates large mixing bubbles, for example a bubble having a largest dimension of 6 inches to 10 feet. In some embodiments, the mixer is located in the anoxic zone. The mixing bubbles are large enough to move wastewater as they rise to the surface and generate a mixing current in the wastewater. The mixing current mixes the wastewater, and bacteria and other microorganisms to promote the bacteria and other microorganisms' conversion of the pollutants contained in the wastewater. The system further comprises an Integrated Fixed-film Activating Sludge (IFAS) system.

  • Patent number: 7520991
    Abstract: A biological removal method of phosphorus and nitrogen includes supplying a mixture gas into a gas holder. Inflow water and return water are supplied into the gas holder to make the mixture gas dissolved in the inflow water and the return water. The return water was provided from a granulation biological reaction tank. The inflow water and the return water including the dissolved mixture gas are transported to the granulation biological reaction tank. A nitrogen-based component is removed from the inflow water and the return water using methan-oxidizing bacteria granulated in the granulation biological reaction tank. Treated water without the nitrogen-based component is transported to an anoxic tank for treatment, and discharged from the anoxic tank.
