Kenneth P. George has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Process and energy-efficient biological treatment system with filtration membrane
    Patent number: 7476322
    Abstract: A membrane filtration system comprising one or more submerged ultrafiltration or microfiltration membrane assemblies at ambient pressure, with mixed liquor is discharged underneath each membrane assembly. In a sequenced batch reactor system, a coarse bubble air diffuser for scouring each membrane assembly is supplied with air only during the backwash cycle of the filtration system and not during the filtration cycle. In a membrane bioreactor system, the biological treatment section is physically separated from the filtration section and fine bubble air diffusion is used in the biological treatment section.
    Type: Grant
    Filed: February 12, 2007
    Date of Patent: January 13, 2009
    Assignee: ITT Manufacturing Enterprises, Inc.

  • Energy-efficient biological treatment system with filtration membrane
    Patent number: 7179370
    Abstract: A membrane filtration system comprising one or more submerged ultrafiltration or microfiltration membrane assemblies at ambient pressure, each membrane assembly positioned 100–240 mm from a nearest wall, baffle, or adjacent membrane assembly and no more than 1 meter above a floor and at least 150 mm below the liquid level. Mixed liquor is discharged underneath each membrane assembly to create a vertical flow velocity in a range of 1–8 mm/second along an entire length of the membrane assembly. In a sequenced batch reactor system, a coarse bubble air diffuser for scouring each membrane assembly is supplied with air only during the backwash cycle of the filtration system and not during the filtration cycle. In a membrane bioreactor system, the biological treatment section is physically separated from the filtration section and fine bubble air diffusion is used in the biological treatment section.
