  • Patent number: 11851352
    Abstract: A continuous flow granular/flocculent sludge wastewater process selects for granule biomass capable of nitrogen and phosphorus removal and controls granule size and concentration of granular and flocculent sludge for optimal nutrient, organic, and solids removal in a smaller footprint. A series of biological process zones lead to a secondary clarifier. Mixed liquor sludge, preferably from an aerobic zone, goes through a classifier or separator processing flow from the aerobic zone, to the secondary clarifier. In a sidestream process that can be included a portion of sludge preferably from an aerobic zone goes through a classifier or separator to selectively produce a granular-rich effluent, and the clarifier may also have a separator to further concentrate granular biomass, most of which is cycled back to an initial multi-stage anaerobic process zone. The anaerobic zone is structured and operated to encourage growth of granules in subsequent process zones.

  • Patent number: 10604433
    Abstract: A method of treating a mixture of microorganisms containing phosphorus and magnesium, by first inducing the mixture microorganisms to release phosphorus and magnesium. Next an emancipation or elutriation is performed. Phosphorus and magnesium-rich liquid is then tapped off as the mixture is thickened, to produce phosphorus and magnesium-rich liquid and phosphorus and magnesium-reduced treated mixture. This treated mixture is placed in an anaerobic digester where ammonia is formed but combines very little with phosphorus or magnesium as these elements have been reduced in concentration. Then the high-ammonia mixture is dewatered, to produce an ammonia-rich liquid, which is combined with the phosphorus and magnesium-rich liquid. In one preferred example a useable struvite product is harvested from this combination. Additionally, the production of nuisance struvite in the anaerobic digester is reduced, in comparison with prior art waste treatment methods.

Microbes can be grown in the presence of the substrates and the metal salts that provide the metal ion for complexing with the 2,3-dihydroxynaphthalene product. Substituents in the naphthalene ring may affect the solubility of the substrates and also the diffusibility and color of the metal complexes. Some of the substrates yield soluble complexes on cleavage and are of particular value in liquid growth media. Other substrates produce less soluble complexes that are more suitable for use in solid agar media. Methods of synthesizing the substrates are described.

  • Publication number: 20150083661
    Abstract: The present invention provides methods for increasing soluble chemical oxygen demand (sCOD) in sewage sludge. These methods include passing the sewage sludge through one or more devices that contains (a) a hollow body provided with a straight-through passage of substantially constant cross-section, the passage having an inlet end and an outlet end for the entry and discharge respectively of the sewage sludge, (b) a transport fluid nozzle substantially circumscribing and opening into the passage intermediate the inlet and outlet ends thereof, (c) a transport fluid inlet communicating with the transport fluid nozzle for the introduction of a transport fluid, and (d) a mixing chamber being formed within the passage downstream of the transport fluid nozzle. The sewage sludge is then passed through a digester.

  • Publication number: 20150076057
    Abstract: To facilitate the collection of grease and water from commercial kitchen exhaust fans the invention provides a collection tank in communication with the drainage spout of the fan assembly. The tank has a lid for sealing the tank, a first reservoir for collecting the stream of grease and water and a second reservoir below the first reservoir for receiving water separated from the grease and water stream in the first reservoir. The first and second reservoirs are separated by a sloping plate. The tank also includes a siphoning apparatus which when connected to a source of high pressure fluid such as water or steam can purge the second reservoir of water and recycle the water back to a fan cleansing operation or to a disposal facility.

  • Publication number: 20150068977
    Abstract: Integrated membrane treatment systems for treatment of an aqueous solution. In embodiments, components, such as an MBR, are integrated with means to recover energy from the system, for example from an RO concentrate, to operate the other components. In embodiments including biological treatment, RO is integrated with other components, such as an MBR with the ROs ability to remove inorganic nitrogen enabling biological treatment to be performed with only partial nitrification and the MBR operated without active pH control. In embodiments, RO is integrated with a chlorine generator to convert chlorides present in the RO concentrate for an in-situ source of oxidizing biocides for disinfection purposes. Chloramines may be generated in-situ from residual ammonia and chlorides in the RO reject. In embodiments, carrier media is employed in a membrane tank to enhance removal of residual organics by the MBR and to also improve effectiveness of membrane scouring.

  • Publication number: 20150024470
    Abstract: The present invention addresses the problem of providing a new microorganism that is useful for efficiently decomposing oils and fats, and a use for said microorganism. According to screening results, a new Yarrowia lipolytica having a high capacity to assimilate free fatty acids was successfully obtained. Efficient decomposition of oils and fats is achieved by causing the Yarrowia lipolytica to act under conditions in which fatty acids that are hydrolysis products of oils or fats are present, or under conditions in which oils or fats are decomposed into fatty acids and glycerol.

  • Publication number: 20140367332
    Abstract: A septic system is provided which receives both sewage and fat, oil, and grease (FOG) at an inlet. The inlet provides fluids to a first chamber. A treatment unit is adjacent the inlet. The treatment unit includes a unit for breaking down solids and mixing them with surrounding liquid. Hydro-jetting water and oxygen into the mixture at high or low pressures achieves oxygenation. Jets injecting an enzyme solution provide for maximum contact with the waste. Injection pressure may be selected to achieve rapid oxygenation at a high level. Optionally, the water may be heated. In another form, hot or cold water is injected at selected times. Temperature may be controlled to keep enzymes working properly. Enzymes may be directly injected and carried by liquid that is hydro-jetted into the fluids being treated.
