  • Method for improving flux in a membrane bioreactor
    Patent number: 8017014
    Abstract: The invention pertains to a method(s) of improving flux in a membrane bioreactor by adding an effective amount of catonic, amphoteric, and zwitterionic polymers, or a combination thereof. The membrane bioreactor impacted by the addition of these polymers is made up of a combination of anaerobic reactors, anoxic reactors, and aerobic reactors and anaerobic digesters.
    Type: Grant

  • ENVIRONMENTALLY FRIENDLY HYBRID MICROBIOLOGICAL CONTROL TECHNOLOGIES FOR COOLING TOWERS
    Publication number: 20090242484
    Abstract: This is a method that is an environmentally friendly hybrid microbiological control compromising a physical method through fine filtration, which removes nutrients, bacteria and suspended solids from open recirculating cooling systems. The method for microbiological control in cooling systems wherein a recirculating fluid containing an oxidising or a non-oxidising biocide or a mixture of an oxidising and a non-oxidising biocide and is passed through a fine filtration system resulting in reduced microbiological matter, suspended solids and nutrients.
