SLUDGE DEWATERING APPARATUS

摘要

A process and apparatus for sludge dewatering including gravity screening and capillary dewatering wherein an endless belt of a screen-like material and an endless belt of a capillary material are selectively functionally utilized separately and in close proximity to effectuate the steps of the process including a repetitive dewatering of the belt as it becomes saturated. The repetitive dewatering step proceeds with the screen-like belt supporting the sludge while the capillary belt is separately compressed, or otherwise dewatered. The process and apparatus further includes a final sludge dewatering section wherein the screen-like belt and the capillary belt are similarly separated.
