- Abstract:
- In the selection of sludge deep dewatering process, the plate and frame filter press is mostly used because the water content is required to be below 60%. However, due to its large footprint, its application in underground wastewater treatment plant (WWTP) has some limitations. This paper introduces the principle and characteristics of the sludge deep dewatering process equipment in the first underground WWTP in northwest China, analyzes the plane and vertical layout, process properties, energy consumption and operation cost of the dewatering workshop, and summarizes the characteristics and applicable conditions of the two-stage sludge deep dewatering process, which could provide reference for the design of similar projects.
