  • Publication number: 20120138543
    Abstract: A charged particle polymer hybrid (CPPH) flocculant is taught, comprising sub-micron size charged particles and a polymer which has been polymerized in the presence of the charged particles wherein the intrinsic viscosity of the hybrid polymer flocculant is less than 930 ml/g. A method is provided for producing freely draining flocculated sediment from a suspension comprising finely divided solids in water. The method comprises dispersing, at increasing concentrations, a charged particle polymer hybrid (CPPH) flocculant into the suspension to determine a starting plateau concentration of CPPH flocculant above which concentration no further increase in the solids loading of the produced floccules is observed. Then, the concentration of dispersed CPPH flocculant in the suspension is maintained at or above the starting plateau concentration. A method is further provided for separating fine solids and water from a suspension comprising finely divided solids in water.

  • Publication number: 20110135797
    Abstract: A method is taught for producing freely draining flocculated sediment from a suspension comprising finely divided solids in water. The method comprises dispersing, at increasing concentrations, a charged particle hybrid polymer (CPHP) flocculant into the suspension to determine a minimum concentration of CPHP flocculant above which a freely draining flocculated sediment is produced that has a minimum permeability of 1 Darcy. Then, the concentration of dispersed CPHP flocculant in the suspension is maintained at or above the minimum concentration. A method is further provided for separating fine solids and water from a suspension comprising finely divided solids in water. The method involves dispersing, at increasing concentrations, a charged particle hybrid polymer (CPHP) flocculant into the suspension to determine a minimum concentration of CPHP flocculant above which a freely draining flocculated sediment is produced that has a minimum permeability of 1 Darcy.

  • Patent number: 7507317
    Abstract: This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with the properties of the reacting components in the bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of 100 kHz to 200 MHz or greater are suitable for the enhancement of the reactions. An electric field of any shape having Fourier components that when applied to a chemical process exhibits growth in the real part of conductivity relative to the low frequency value is of particular importance.
