    摘要: A sludge separation system including a reversible refrigeration circuit having a set of sludge receiving heat exhangers which alternate between evaporating and condensing functions to periodically freeze and thaw sludge to effect the separation of solid constituents therein, and a compressor which operates only when the pressure differential of the refrigerant in the heat exchangers is insufficient to force the refrigerant from the evaporator to the condenser.
