Abstract:
A method of treating waste, the method comprising the acts of:(a) providing a cold waste solids source for maintaining cold waste solids, a hot waste solids source separate from the cold waste solids source for maintaining hot waste solids, and a heat exchanger remotely located from and fluidly interconnected with the cold waste solids source and the hot waste solids source;(b) passing a volume of cold waste solids from the cold waste solids source through the heat exchanger;(c) passing a volume of hot waste solids from the hot waste solids source through the heat exchanger to transfer heat from the hot waste solids to the cold waste solids; and(d) passing at least a second time through the heat exchanger at least a portion of one of the volume of cold waste solids and the volume of hot waste solids passed through the heat exchanger to transfer heat from the hot waste solids passing through the heat exchanger to the cold waste solids passing through the heat exchanger.
