  • Method and apparatus using hydrogen peroxide and microwave system for slurries treatment
    Patent number: 8444861
    Abstract: A method and apparatus for treating slurries of organic solids is disclosed. A slurry of organic solids is admixed with hydrogen peroxide, followed by exposure to microwave irradiation resulting in the heating of the mixture and enhanced hydrolysis of the organic solids. The treated slurry of organic solids can then be further treated in a variety of downstream processes, including solid separation, digestion and fermentation. The supernatant portion of the treated slurry of organic solids can be a source from which to recover compounds such as nutrients (for example nitrogen, phosphate, potassium, magnesium, calcium) or industrial organic compounds (such as acetic acid, propionic acid, butyric acid), or as a source of readily biodegradable organic compounds for supplementing a biological wastewater treatment process, digester or fermenter.
    Type: Grant

    Date of Patent: May 21, 2013
    Inventors: Kwang Victor Lo, Ping Liao, Wayne Wong, Weigang Miles Yi, Weng I Chan, Frederic A. Koch, Donald S. Mavinic
