  • Patent number: 11027997
    Abstract: The present invention solves the problem of environmental pollution created by animal waste and converting animal waste to reusable water in the earth. The invention does this by a device that is capable of receiving animal waste and breaking down the waste into different components by the help of a decomposing catalyst such as a septic pack, filtering the resulting solution and finally producing a filtered liquid that enters the earth being cleansed by the process. The present invention comprises a filter device, a tank unit, a filter unit, a first opening positioned on a top surface of the tank unit; a second opening positioned on a bottom surface of the tank unit; wherein the tank unit is capable of receiving animal waste through the first opening; at least one hole at a bottom surface of the filter unit; wherein the tank unit is placed over the filter unit.

  • Patent number: 11008821
    Abstract: A process for recovering weight material for reuse in drilling fluids from a previously unavailable source of feed stock. The process described herein includes a process of cleaning drilling waste through either low temperature thermal or solvent washing to remove hydrocarbon or water based drilling fluid contamination. The cleaned drilling waste, substantially free of liquids is sifted and the bulk fraction is further treated by employing conventional separation technology to recover a high gravity solids phase while discarding low gravity solids phase as tailings. Additionally, described is a process where the recovered high gravity solids phase can be reused as a high density weight material, or lower cost weight material, either of which is desirable to the drilling of modern oil and gas wells. The process of adding drilling fluid back into the recovered weight material to simplify the process of transporting the weight material into an active drilling fluid system is also described.

  • Patent number: 10995025
    Abstract: A liquid flow distribution system comprises a flow chamber and a rotor. The flow chamber has a flow chamber inlet, a flow chamber outlet and a chamber flow path extending from the flow chamber inlet to the flow chamber outlet. The flow chamber path is curved so as to generate a generally vortical flow in liquid passing through the chamber flow path. The rotor has a plurality of rotor blades rotatably mounted about a rotor axis. The rotor is mounted in proximity to the flow chamber outlet and positioned such that a flow of liquid exiting the flow chamber outlet impacts one or more of the rotor blades to rotationally drive the rotor. Rotational driving of the rotor in turn disperses liquid impacting the rotor blades.

  • Patent number: 10981817
    Abstract: A technique for wastewater treatment involves ensuring that all paths for wastewater must pass through at least one porous microbial support to go from the inlet to the outlet, and allowing a biofilm to grow on the porous microbial support under microaerobic conditions (concentration of oxygen between 0.05 and 0.35 mg/L). The biofilm formed comprises a population of anaerobic microbes for digesting organics in the wastewater including methanogenic microbes, and an aerobic methanotrophic and heterotrophic population that catabolizes methane from the methanogenic microbes, and oxygen from the injector, to produce heat. The support may be an electrode, and the technique is applied in a microbial electrolysis cell, with substantial COD removal rates.

  • Patent number: 10967301
    Abstract: A settling or sedimentation tank including inlet structures arranged, through whose inlet opening the suspension to be separated flows to the tanks, the height of which can be variably adjusted. In addition to the height variability of the inlet opening, the volumetric flow flowing out of the inlet structure can, depending on the actual load, be directed by forming a horizontally flow-through inlet opening or a vertically flow-through inlet opening and can optionally be divided into horizontal and vertical partial flows QI and QII. As a result of the horizontal inflow, the capacity of the sedimentation tank increases at high loads, and as a result of the vertical inflow, the volume flow through the sedimentation chamber and the turbulent energy in the sedimentation chamber decrease at low loads, so that the retention of fine suspension in the sedimentation tank is increased and thus the effluent quality is improved.

  • Patent number: 10934196
    Abstract: In a lagoon-based wastewater treatment process, reduction of total nitrogen in the product water is facilitated by including a denitrification process. In an initial phase of the overall process, raw wastewater is processed in a lagoon to reduce BOD5 and TSS. Nitrification occurs in the lagoon and/or in a distinct or separate nitrification reactor. At least a portion of product water that has been nitrified is mixed with a portion of raw, incoming wastewater, and the mixture is introduced into an anoxic region of the lagoon in a manner that promotes denitrification within the anoxic region of the lagoon.

  • Patent number: 10927008
    Abstract: Method and device for biogas upgrading and hydrogen production from anaerobic fermentation of biological material under production of energy rich gases selected among methane and hydrogen or a combination thereof. The method comprises addition of hydrogen gas to a fermentation step to enhance the methane: CO2 ratio in the raw biogas produced. At least part of the raw biogas is subjected to a step of sorption enhanced reforming without prior separation of CO2, using CaO as an absorbent to capture CO2 from the raw biogas as well as CO2 released in the reforming reaction. CaO is regenerated in an endothermic reaction using heat at least partially provided, directly or indirectly, by the bio-gas to be upgraded, thereby producing substantially pure hydrogen and substantially pure CO2.
