Abstract
An ash management trench system is provided for harvesting byproducts from sluice water, such as a discharge from a power plant. The system comprises a first section comprising at least one flow control structure. The at least one flow structure is typically configured to capture a predetermined byproduct. The system further comprises a second section comprising a stilling basin. The second section is coupled to the first section by a connection structure.
Claims21
An ash management trench system for harvesting byproducts, the system comprising:
- a first section comprising at least one flow control structure to capture a predetermined first byproduct;
- and
- a second section comprising a stilling basin, the second section being coupled to the first section, wherein the stilling basin is structured for separation and settling of a predetermined second byproduct;
- wherein the at least one flow control structure comprises a mesh screen, having a plurality of apertures of a predetermined dimension so as to prevent the predetermined first byproduct with a dimension greater than the predetermined dimension from passing through the at least one flow control structure;
- wherein the first section comprises at least one flocculant discharger configured to release one or more flocculants into the first section at a predetermined application rate of flow and at predetermined time intervals, wherein the at least one flocculant discharger is positioned at least partially below ground and wherein the at least one flocculant discharger comprises a supplemental heating apparatus to impede freezing of the one or more flocculants, wherein the at least one the flocculant discharger comprises a metered pump, and wherein the at least one flocculant discharger discharges flocculant at multiple locations along the length of the first section;
- and
- a casting area, wherein the casting area is structured to store excavated predetermined first and second byproducts received from the first section or the second section.

An ash management trench method for harvesting byproducts, the method comprising:
- providing a first section comprising at least one flow control structure to capture a predetermined first byproduct, wherein the at least one flow control structure comprises a mesh screen having a plurality of apertures of a predetermined dimension so as to prevent the predetermined first byproduct with a dimension greater than the predetermined dimension from passing through the at least one flow control structure;
- providing a second section comprising a stilling basin, the second section being coupled to the first section, wherein the stilling basin is structured for separation and settling of a predetermined second byproduct;
- and
- transporting the settled predetermined first byproducts received from the first section and the predetermined second byproduct received from the second section to a casting area;
- and
- wherein the first section comprises at least one flocculant discharger configured to release one or more flocculants into the first section at a predetermined application rate of flow and at predetermined time intervals, wherein the at least one flocculant discharger is positioned at least partially below ground and wherein the at least one flocculant discharger comprises a supplemental heating apparatus to impede freezing of the one or more flocculants, wherein the at least one the flocculant discharger comprises a metered pump, and wherein the at least one flocculant discharger discharges flocculant at multiple locations along the length of the first section.
