Knowledge Base

Q

The biggest difference between the stacked screw dewatering machine and the plate and frame filter press is that they process different types of sludge. The stacked screw dewatering machine is used to process organic sludge, while the plate and frame filter press is used to process inorganic sludge. It is recommended to use a screw stacking machine to treat the sludge generated after biochemical treatment. The screw stacking machine has a good effect on treating organic sludge, but if a plate frame is used, it is easy to clog the filter cloth. If there is a large amount of mud in the sludge

Q

The use of a stacked screw sludge dewatering machine for the dewatering of oily sludge has certain feasibility, but there are also some precautions to be taken. The following is a specific introduction:   Working Principle   -Concentration section: After the oily sludge enters the stacked screw sludge dewatering machine, most of the free water is separated from the sludge in the concentration section by gravity, and the sludge is preliminarily concentrated to prepare for subsequent dewatering.
