Abstract
The system for a continuous dewatering recirculating for removing particulate such as coal combustion residue from a water stream. The system includes multiple dewatering and recirculation containers, each having a submerged flight conveyor and lamella settlings plate located therein, at least one dewatering and recirculation container receives ash water stream overflow.
Claims5
A method for reducing the particulate in a bottom ash water stream comprising:
- a) receiving a bottom ash water stream overflow in a first one of a plurality of continuous dewatering and recirculation containers from a second one of a plurality of continuous dewatering and recirculation containers, each of the plurality of continuous dewatering and recirculation containers containing a submerged flight conveyor therein and at least one lamella settling plate located therein,
- b) maintaining a substantially constant water level in the second one of the plurality of continuous dewatering and recirculation containers for filtering the coal combustion residue water stream;
- and
- c) selecting the first one of the continuous dewatering and recirculation container from among the plurality of continuous dewatering and recirculation containers for receiving ash water stream overflow.
