Comparison between screw press and plate and frame filter press

 

In the field of sludge dewatering, screw press sludge dewatering machine and plate and frame filter press are very common sludge dewatering equipment. So, what is the difference between screw press sludge dewatering machine and board frame? Under what circumstances is it suitable for screw press sludge dewatering machine and plate and frame filter press?

Screw press sludge dewatering machine is a water treatment system widely used in municipal sewage treatment projects and petrochemical, light industry, chemical fiber, papermaking, pharmaceutical, leather and other industrial industries.

Plate and frame filter press is the first machine used in chemical dehydration. Although the plate and frame filter press is generally operated intermittently, with large investment in infrastructure equipment and low filtration capacity, it is still widely used in some sewage plants because of its advantages such as high solid content of filter cake, clear filtrate, high solid recovery rate and low reagent consumption.

Screw press sludge dewatering machine has a high degree of automation and long service life. The treatment capacity of plate and frame is large, and the water content of sludge is low. In fact, the advantages and disadvantages of these two types of devices should be analyzed from the application scenario.

The application field difference between screw press sludge dewatering machine and plate and frame filter press:

Screw press sludge dewatering machine is suitable for the field of organic sludge. Plate and frame are more suitable for the field of inorganic sludge. Although many times, the application fields of the two are not clearly distinguished, and they can even be replaced by each other in many scenarios. Therefore, the equipment can be selected according to whether the sludge is organic or inorganic, so as to determine whether it is better to dewater the spiral sludge and whether it is better to use plate or frame.
