Sludge Dewatering Machine Screw Press For Municipal & Industrial Wastewater

The Sludge Dewatering Machine Screw Press is a compact and efficient solid–liquid separation device for continuous sludge dewatering. It uses a slow-rotating screw and ring structure to separate water while preventing clogging through a self-cleaning design. With automatic operation, low noise, and low energy consumption, it offers excellent cost performance and is widely applied in municipal and industrial wastewater treatment plants, as well as paper making and printing industries.

Unattended and Automatic Operation

The Sludge Dewatering Machine Screw Press supports fully automatic and continuous operation, requiring minimal manual intervention and enabling reliable unattended running.

Self-Cleaning Design with Water and Energy Saving

Mechanical squeezing dewatering ensures a compact design and low energy consumption, while the self-cleaning structure prevents clogging and reduces water and maintenance needs.

Wide Applicable Sludge Concentration Range

The Sludge Dewatering Machine Screw Press can operate efficiently across a wide range of sludge concentrations, making it suitable for various municipal and industrial sludge dewatering applications.

Metering Tank

The sludge is delivered to the metering tank through the slugge transfer pump,and the surplus part flows back to the sludge storage tank from the return pipe.

Flocculation Mixing Tank

The metered sludge is fully stirred ang mixes with the injected polymer coagulant in the flocculation mixing tank to from a good alum flower.

Dehydration Unit

After the sludge enters the dehydration body through the sludge inlet,the gravity concentration occurs in the concentration part of the front section,and most ofthe liquid is discharged; the sludge is fully dehydrated in the dehydration part due to the continuous rise of the pressure in the iner cavity,The dewateringbody of sludge compressor does not include the dewatering part.

Sludge Outlet / Concentrated Sludge Outlet

The back pressure plate set at the outlet produces a blocking force in the opposite direction,so as to further increase the pressurein the cavity of the body andmake the sludge more fully dehydrated and discharged from the outlet in the form of mud cake."The sludge thickener discharges the concentrated sludgethrough the sludge outler".There is no back pressure plate at the outletof sludge thickener.
