Basically, both the public & private sectors are required to dispose the sludge which is approved by industries. Sludge dewatering is totally focused on the reducing weight as well as volume of sludge & also on cost & transportation services. First step of Sludge dewatering is removing water from it so by removing water it will impact on reducing volume & weight of sludge.
Also the pitch of the screw flight is gradually increasing making the valley / volume available for the sludge narrow towards the outlet so that flocculated sludge that is concentrated by gravity filtration is further dewatered by compression.
The main purpose of Sludge dewatering machine is to minimize the handling and disposal. Sludge dewatering press is the most cost effective method of dewatering, and hence helps to sustain the environmental objectives of company.
Screw Press Dehydrator Features
No secondary pollution
The screw shaft rotational speed about 2~3r/min, no vibration and noise is very small .
Only need a small amount of water for self-cleaning, no secondary water pollution.
Sludge runs at a slow operating condition. The smell does not spread.

Screw Press Dehydrator Application
Low Power Consumption
Simple and short start-up and shut down procedures
Continuous operation. Hence continuous output can be obtained
Process can be automized
Only electricity and water supply for cleaning is required, and that too in less amount
For a multi-channel machine, one or more channels may be removed for maintenance purposes, while the machine with the remaining channels may still be operated
