Screw Press Dehydrator Multi Disc Sludge Dewatering WWTP

Multi Plate Screw Press Sludge Dewatering System
 

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 Technical Parameters

 

 
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 Benefits

• Low Running Cost

• Power-use: less than 5% of centrifuge.

• Water-use: less than 0.1% of belt filter press. Polymer: saving around 60%

• Room: saving more than 60% of the investment for dehydration room

• Non-clogging

• Self-cleaning with small amount of water

• Suit for Oily Sludge​

Screw Press Dehydrator Application

• Simple arrangement
• 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
• No clogging. Cleaning is automized and is easy
• Long life of discs
• No external lubrication system is required
• Flocculator built in the Screw press
