Abstract: A green-engineered mulch product and methods for making same are disclosed. The mulch product includes a coating of aluminum-based water treatment residuals which makes the product “green.” Furthermore, coating aluminum-based water treatment residuals on mulch eliminates the problem of the low hydraulic conductivity of aluminum-based water treatment presiduals and makes it feasible to utilize its pollutant removal potential without requiring any modification to existing best management practices or additional maintenance.

Abstract: The present disclosure discloses a silicon-aluminum-iron composite material and a preparation method therefor and use thereof, and belongs to the technical field of wastewater treatment. The silicon-aluminum-iron composite material comprises an inner core and an outer shell wrapping the inner core; the inner core is a silicon-aluminum-based hollow sphere; the outer shell contains iron element; and there are holes on the silicon-aluminum-iron composite material. The silicon-aluminum-iron composite material of the present disclosure improves the specific surface area of the silicon-aluminum-iron composite material through structural adjustment. When it is used to adsorb heavy metal ions, the adsorption sites are correspondingly increased, which finally improves the adsorption capacity for heavy metal ions.

Abstract: A method for removing a contaminant from an environment is described comprising the steps of: (i) heating a reduced and passivated getter material containing crystallites of a metal in elemental form encapsulated by a layer comprising an oxide of the metal to a temperature in the range (TT−X) to (TT+Y), where TT is the Tammann temperature of the metal in elemental form in degrees Centigrade, X is 400 and Y is 200, to form an activated getter material having active surface for contaminant removal and (ii) exposing the activated getter material to the environment containing the contaminant.
