Regarding to the Clients’ questions about the Comparison of Decanter Centrifuge and Filter Press, GN Company Technical Team had research and prepared report, details as follow.
1. Discharged Cake Moisture
1.1 Decanter Centrifuge
Decanter centrifuge is using centrifugal force to separate solid and liquid under normal pressure, thus the discharged solid cake with relative high moisture, about 50~80%.
1.2 Filter Press
Filter press is dewatering the sludge by high pressure extrusion and filtering, discharged solid cake would be dryer than same out of decanter centrifuge, about 45~75%.
2. Applicability
2.1 Decanter Centrifuge
Decanter centrifuge can be widely used for sludge with low viscosity sludge, and high viscosity such as the oily sludge.
2.2 Filter Press
Filter press normally will not be used for oily sludge dewatering due to the filter membrane blocking issue.
Clients shall consider factory situation, labor cost, working condition, sludge type, plant area, investment and so on to decide to use filter press or decanter centrifuge.
GN Company is a professional manufacturer of Decanter Centrifuge for 13 years, with bowl diameter of 220~760mm, and capacity of 1 ~120 m3/hour.
