  • Extracts of durian fruit for use in skin care compositions
    Publication number: 20070116789
    Abstract: The present invention relates to compositions comprising extracts of Durio zibethinus. The compositions of the present invention are useful for improving the appearance, texture, and/or moisture of mammalian skin. In particular, the compositions of the present invention decrease inflammation in the skin, inhibit matrix metalloprotease-9, which degrades skin proteins such as collagen and elastin, and inhibit melanogenesis in the skin.
    Type: Application

  • Process and system for enhanced nitrogen removal in a wetland and recirculating sand filter wastewater treatment system
    Patent number: 7128839
    Abstract: A process and system for enhanced nitrogen removal in a wastewater treatment facility comprises a constructed wetlands and a recirculating sand filter. The effluent from the constructed wetlands passes through the recirculating sand filter to facilitate ammonia conversion to nitrates. A portion of the wastewater is recycled from the recirculating sand filter to the constructed wetlands to provide for anaerobic denitrification of the wastewater in a nutrient rich environment.

  • Process and system for enhanced nitrogen removal in a wetland wastewater treatment facility
    Patent number: 6447682
    Abstract: A process and system for enhanced nitrogen removal in a wetlands wastewater treatment facility is disclosed. Air is bubbled into the wetland to form an overall aerobic zone to enhance nitrification of the ammonia in the wastewater. A portion of the effluent is recycled back to the nutrient rich, anaerobic zone of the inlet of the wetland to enhance denitrification of the wastewater.
