  • Process for producing high solids colloidal silica
    Patent number: 10087081
    Abstract: The invention provides a method for improving the effectiveness of colloidal silica. The method involves removing enough charged impurities from the colloid to prevent the charged particles from causing the colloid to become a viscous gel. The method however also involves not removing too many charged particles so the silica material doesn't gel by cross-linking with itself. This method is quite effective because it recognizes that materials that have accumulated during the formation of the colloid do perform an important function, but they can perform better at a lower concentration.

  • Reduction of hydrogen sulfide and/or malodor gassing from water via the addition of peroxyacetic acid/hydrogen peroxide product
    Patent number: 10081561
    Abstract: The invention provides methods and compositions for reducing the malodorous sulfide gas released by a wastewater treatment system. The method preserves the vitality of waste consuming organisms within the system. The method comprises the steps of: determining the SRP PAA demand of the system, determining the aerobic PAA demand of the system, and adding a composition in an amount such that it is in excess of the SRP PAA demand but is below the aerobic PAA demand. Even though the composition increases the amount of sulfates within the wastewater it reduces the amount of SRP which prevents the malodorous sulfite gas release. The composition comprises at least one percarboxyacid.

  • Addition of aluminum reagents to oxoanion-containing water streams
    Patent number: 10071923
    Abstract: The removal of oxoanions from an aqueous stream having a concentration of a metal cation and a concentration of an oxoanion that varies over time may involve continuously monitoring the concentration of the metal cation and the concentration of the oxoanion to provide a current metal cation concentration and a current oxoanion concentration. A metal cation source and an aluminum reagent may be added to the aqueous stream based on the measured current metal cation concentration and the current oxoanion concentration.
