SCREW TYPE SLUDGE DEHYDRATOR
Screw Type Sludge Dehydrator
Product details
Comparing with the other devices (belt filter press , centrifugal machine), TECHANGE Volute type sludge dehydrator has many advantages such as energy-saving, capable of working 24/7, fully automation ,lower polymer consumption , achieve a dry matter content of 15%-70%, minimal flush water consumption, minimal maintenance & operation cost , minimal noise, etc. Suitable for any type of sludge, for example, sludge from municipal, beverage, slaughter breeding, printing and dyeing, chemical, oil, paper making, pharmaceutical etc.
Working Principle
Sludge will be transported to the dewatering department after being thickened in the thickening department. In the advancing process, great pressure has been produced because of the gradually decreasing filter spacing and screw distance, and the back platen clogging. Then the volume decreases continuously , and the purpose of fully dewatering will be achieved.

Technical Specification
Pre-thickening Screw Sludge Dehydrator
Product details
The equipment is widely used for lower consistency sewage wastewater and is composed of thickening part& dehydration part, The consistency range can be from 2500mg/L to 20000mg/L, thus the investment can be reduced a lot. It’s a professional integrated thickening & dewatering sludge dehydrator .
Screw Sludge Thickener
Product details
The sludge can be condensed rapidly and continuously in the secondary sedimentation tank, meanwhile, after condensed and separated, the sludge concentration can be adjusted between 90% and 96% stably. it’s a special thickener equipment.
Application
It is the pre-treat device of sludge deep dewatering ,also as the auxiliary equipment of ultra high pressure elastic presser, membrane filter presser.
Instead of condensed tank, work as the pre-treat device of the sludge dewatering system.
