  • Patent number: 11396466
    Abstract: A method for the treatment of water, the method comprising the steps of anaerobic uptake and storage of at least a portion of the organic components in the water by a heterotrophic denitrifying biomass absorption of ammonium ions with an ammonium ion absorbent; and aerobic oxidation of the absorbed ammonium by a nitrifying biomass comprising ammonium oxidizing microorganisms, wherein the step of aerobic oxidation of the absorbed ammonium is preceded by the step of exposing at least a portion of the nitrifying biomass to atmospheric oxygen.
    Type: Grant
    Filed: May 3, 2018
    Date of Patent: July 26, 2022
    Inventors: Ralf Cord-Ruwisch, Liang Cheng, Raphael Marie-Guillaume Flavigny, Md Iqbal Hossain

  • Publication number: 20170233276
    Abstract: A method for the treatment of organic waste, the method comprising alternating steps of anaerobic digestion and aerobic composting conducted in a single reactor vessel, wherein at or about the completion of the anaerobic digestion step at least a portion of any free draining fluid from the reactor vessel is directed for reuse in subsequent anaerobic digestion steps, and solids remaining in the reactor vessel from the anaerobic digestion step are subjected to a dewatering step from which a liquid is obtained that is ultimately also directed, at least in part, for reuse in subsequent anaerobic digestion steps. A method for the management of biology in a batch process, wherein the batch process is an anaerobic digestion process, is also described.

  • Patent number: 8216472
    Abstract: The present invention relates to a method of treating a liquid to extract at least one of carbon, sulphur, nitrogen or phosphate from liquids such as waste water. Preferably, the invention is employed to remove nitrogen from waste water. In an alternate for the invention provides a wastewater treatment system.

  • Patent number: 8182604
    Abstract: A method of forming a high strength cement in a permeable starting material, the method comprising the step of combining the starting material with effective amounts of (i) a urease producing micro-organism; (ii) urea; and (iii) calcium ions and wherein the effective amount of the urease producing organism provides a urea hydrolysis rate, under standard conditions, of 0.5-50 mM urea hydrolysed.min?1.
