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.
Claims20
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 at least one of a stop log system, having a plurality of apertures of a predetermined dimension so as to prevent the predetermined first byproducts with a dimension greater than the predetermined dimension from passing through the at least one flow control structure;
- 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 system for harvesting byproducts, the system comprising:
- a first section comprising at least one flow control structure to capture a predetermined first byproduct, the at least one flow control structure comprising the addition of at least one flocculant;
- a second section comprising a stilling basin, the second section being coupled to the first section in series, wherein the stilling basin is structured for separation and settling of a predetermined second byproduct;
- a casting area, the casting area comprising a collection drain;
- a protective geotextile layer adjacently coupled to the first section and the second section;
- and
- wherein the at least one flow control structure comprises at least one stop log system, having a plurality of apertures of a predetermined dimension so as to prevent byproducts with a dimension greater than the predetermined dimension from passing through the at least one flow control structure.
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 at least one stop log system, having a plurality of apertures of a predetermined dimension so as to prevent byproducts 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 in series, wherein the stilling basin is structured for separation and settling of a predetermined second byproduct;
- receiving sluice water via a headwall in the first section, the sluice water comprising byproducts;
- transporting the sluice water through the first section and into the second section via the at least one flow control structure, the second section enabling the settlement of the predetermined second byproduct;
- and
- transporting the settled second byproduct to a casting area.
