摘要:
A method of controlling the movement of biosolids before, during, and after land application. This method aids in management of the problematic movement (i.e., runoff and leaching) of biosolids' components that have been shown to be harmful to human and/or environmental health through both direct and indirect routes of exposure. This method requires that water-soluble polyacrylamide(s) (WSPAM) be combined with the biosolids prior to land exposure.
摘要:
Compositions provide dry soils, plants, or both, with moisture, and optionally, other active ingredients. The compositions can be used as the sole source of moisture for a growing plant or as an adjunct source during periods of diminished watering. The compositions are particularly well suited for use in household and potted plant applications. The compositions include an active ingredient selected from the group consisting of a polymer, a surfactant, and combinations thereof.
摘要:
The invention relates to a clay-containing mixture or blend capable of forming a moisture resistant gel, which comprises a powdered or ground smectite and/or a smectite-containing natural rock and at least 0.8 - 10 % by weight, calculated for the smectite content, of an at least partially water-soluble and/or water swellable polymer and optionally at least 0.5 % by weight of a solid activating agent. Such a mixture may also additionally comprise as a diluting agent more than 0.5 % by weight of one or more solid inert filler(s); this diluted version is termed in the specification as a blend.
