  • Patent number: 10689276
    Abstract: The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump. The ozone and the oxygen are turned into ultra-fine bubbles via cavitation action within the pump, facilitating the dissolution of the oxygen and ozone within the water. The water mixed with the oxygen and the ozone is subsequently supplied to a line atomizer, where the dissolution of the ozone within the mixture is completed. The combined use of the cavitation pump and the line atomizer can lead to a substantially complete dissolution of the supplied ozone within water that needs to be disinfected, allowing to easily achieve the concentration of ozone necessary for water disinfection. Due to this efficiency, the system and method described are highly scalable and suitable for water purification at water purification plants of various sizes.

  • Patent number: 10626035
    Abstract: Disclosed is a sequencing batch reactor (SBR) for sewage treatment. The SBR is applicable to an energy-producing sewage treatment system. The SBR includes a treatment tank and a hybrid bacterial strain screening tank. The treatment tank removes ammonium contained in supernatant liquid using anaerobic ammonium-oxidizing (anammox) bacteria. The hybrid bacterial strain screening tank screen anammox bacteria granules out by passing the supernatant liquid discharged from the treatment tank through the hybrid bacterial strain screening tank. The SBR generates biogas using the anammox bacteria and reduces the nitrogen content in the supernatant liquid. The SBR can separate the anammox bacteria granules with high separation efficiency, thereby shortening sewage treatment time and recycling activated sludge, resulting in a dramatic decrease in the amount of waste sludge.

  • Patent number: 9862628
    Abstract: In a submerged membrane bioreactor (MBR or SMU), diffusers are used to eject air bubbles, primarily to facilitate the movement of mixed liquor past the membrane surfaces, cleaning and scouring the surfaces of the membranes with the mechanical energy of the combined air/liquid/solids movement. Oxygen transfer from the bubbles into the mixed liquor is often a secondary goal, for supplying oxygen to biological processes. The invention involves the use of a specific bubble diffuser, oriented at a selected upward angle, to enable a single style diffuser to accomplish simultaneous generation of mid-size and fine bubble aeration, with adjustment of the tilt angle varying the percentages of mid-size and fine bubble aeration. The angle selection, along with the number of diffusers and air volume selected, allows achievement of target liquid movement through the MBR.

The method includes mixing enzymes into the fluid waste material, compressing the fluid waste material with the compressor, injecting air into the compressed fluid waste material, and determining whether the fluid waste material is at a desired cleanliness, and if not, recirculating the fluid waste material through the compressor.

  • Patent number: 8980091
    Abstract: A method and system for controlling dissolved oxygen levels in a secondary treatment system of a wastewater treatment facility that can employ a membrane bioreactor in which oxygen introduction into mixed liquor is controlled to prevent bulking and minimize generation of extra cellular polymeric substances. The control is exercised by insuring that dissolved oxygen levels within the mixed liquor do not fall below a minimum system level at which microorganism stress would occur. This is done by setting a minimum dissolved oxygen level control point equal to a sum of the minimum system level and an adjustment factor determined on the basis of oxygen uptake rate and time delays inherent in sensing oxygen levels and changes thereof within the mixed liquor. The minimum system dissolved oxygen level can be continually calculated on the basis of an inferred food to mass ratio that would vary with sensed mixed liquor suspended solids.

  • Patent number: 8974670
    Abstract: The present invention provides an aeration lateral system designed to be site specific for new septic disposal areas or retro fitting to existing septic disposal areas to break up the biological clogging sludge mat at the interface of the wastewater and imported sand or native soil fill under or adjacent to disposal areas of a typical septic system. The lateral system provides uniform or other site specific distribution of fluids about the bio-mat of a wastewater disposal area, with lateral spacing and hole spacing varying based on the type of disposal area being utilized. The lateral system can also be utilized to provide continuous low volume air supply system to a wastewater disposal area or peat filter module. The air lateral installation includes methods to minimize airflow disturbance of the soil and methods to prevent air leakage.

  • Patent number: 8956540
    Abstract: A process for treating water that includes ammonium. The water is directed to a biological reactor and the quantity of nitrates formed in the reactor and the quantity of ammonium reduced in the reactor is determined. A ratio of the quantity of nitrates formed to the quantity of ammonium reduced is determined. Further, the percentage of ammonium reduced is also determined. The water in the biological reactor is aerated by injecting oxygen into the reactor where the amount of oxygen injected is a function of the ratio and the percentage of ammonium reduced in the reactor.

  • Patent number: 8945378
    Abstract: A method for cleaning waste water is provided whereby the waste water is led through a throughput tank having filler materials to which aerobic microorganisms are adhered and wherein the throughput tank is ventilated with an oxygen-containing gas. As filler materials, materials are used which have a specific weight approximately equal to the specific weight of the waste water whereby the filler materials are suspended in the waste water. The inflow of the waste water into the throughput tank and the ventilation of the throughput tank is affected from bottom of the throughput tank and in such a gas amount that the waste water and the filler bodies suspended therein are mixed and the microorganisms on the filler bodies are supplied with sufficient oxygen. The device has a throughput tank with a tank bottom, a tank wall, wherein the inflow connecting pipe and the ventilation arrangement are arranged on the tank bottom and the outflow connecting pipe is arranged at the upper area of the throughput tank.

  • Patent number: 8940159
    Abstract: The invention includes a method for the optimization of the soluble CO2 concentration in the aeration basin of an activated sludge system, which significantly improves the specific growth rate of the nitrifying bacteria. The result is a reduction in capital and energy costs for municipalities. The rate of nitrification is a product of the nitrifying bacteria biomass concentration and the specific growth rate of the bacteria. In the activated sludge system, the biomass concentration is maintained at high concentrations by reducing the wasting rate. The specific growth rate is a function of the ammonium concentration and the environmental conditions. Here, the inventors show that growth of nitrifying bacteria is inhibited when the soluble CO2 concentration is elevated beyond certain parameters. Elevated soluble CO2 concentration also reduces the pH, which also impacts the rate of growth of nitrifying bacteria.

  • Patent number: 8894852
    Abstract: A system for producing and supplying a coolant to a filtration sub-system, and for reconditioning and recombining a return flow of used coolant. A main reservoir is in two way communication with the filtration sub-system via a clean coolant outlet and a dirty coolant return. An inlet feeds an untreated water supply to a de-ionization canister. A mixing valve in communication with the inlet recombines a remaining untreated portion of the water supply with the de-ionized portion. A mixing pump intermixes the water supply with a chemical concentrate to produce a coolant delivered to a main reservoir. A volume of coolant is drawn through an outlet from the reservoir and communicates the coolant to a particle filter, a chiller, and prior to outputting to the filtration sub-systems. The used return coolant is filtered and reintroduced to the main reservoir.
