Abstract
A method and system for removing a slurry from a surface impoundment to create a dewatered particulate cake on a filter bed is disclosed.
Claims10
A process for remediating a coal ash pond to produce a coal combustion residual material-based cake bed, the process comprising the steps of:
- a. Extracting an ash slurry from a coal ash retention pond;
- b. Scalping the ash slurry to separate coarse ash components and fine ash components;
- c. Placing the fine ash components in a clarifier or thickener to create a thickened underflow;
- and
- d. Depositing the thickened underflow upon a mechanical dewatering device including a vacuum belt filter, or belt filter press, or plate filter press to create a cake bed consisting of fine components.

A process for remediating a surface impoundment to produce a cake bed composed of particulate that is naturally present in the impoundment. the process comprising the steps of:
- a. Extracting a slurry from a surface impoundment;
- b. Scalping the slurry to separate coarse components and fine components;
- c. Placing the fine components in a clarifier or thickener to create a thickened underflow;
- and
- d. Depositing the thickened underflow upon a mechanical dewatering device selected from the group comprising vacuum belt filter, belt filter press, and plate filter press to create a cake bed consisting of fine components.
