  • Method for removing ionic species contained in an aqueous phase using a sol gel composite material
    Patent number: 8962781
    Abstract: Disclosed is a method for removing an ionic species contained in an aqueous phase. The method includes contacting an aqueous phase containing the ionic species with a sol-gel composite material, where the sol-gel composite material is a sol-gel composition having a porous matrix and containing a reactive metal incorporated into at least a portion of the porous matrix, under conditions sufficient to remove the ionic species contained in the aqueous phase.
    Type: Grant
    Filed: September 9, 2014
    Date of Patent: February 24, 2015
    Assignee: ABS Materials Inc.
    Inventor: Hanbae Yang
  • Method for removing ionic species contained in an aqueous phase using a sol gel composite material
    Patent number: 8921504
    Abstract: Disclosed is a method for removing an ionic species contained in an aqueous phase. The method includes contacting an aqueous phase containing the ionic species with a sol gel-derived composite material, where the sol gel-derived composite material is a sol gel-derived composition having a porous matrix and containing a reactive metal incorporated into at least a portion of the porous matrix, under conditions sufficient to remove the ionic species contained in the aqueous phase.

  • Bi-phasic bioretention system
    Patent number: 7967979
    Abstract: An anaerobic to aerobic sequence enhances biological degradation of many organic pollutants. Exemplary embodiments provide systems and methods for effective treatment of storm-water runoff pollutants such as hydrocarbons, nitrates, phosphorus, and heavy metals using sediment filtration and adsorption, and biochemical processes under bi-phasic bioretention conditions. By integrating these pollution cleanup pro-usages into a single unit, this apparatus optimizes retention time of the runoff through the system and maximizes removal rates of runoff pollutants, resulting in more reliable and efficient treatment mechanism than previous systems.
