R+F Screw Press Series
Maximum efficiency, minimal maintenance, and superior cake dryness for industrial and municipal applications.
R+F Screw Press Quick Facts
01
+32% Dryness
Superior cake solids compared to conventional belt filter presses. Reduced disposal costs from day one.
02
Low-Speed Wear
Operating at only 40–80 rpm. Minimal mechanical stress ensures maximum uptime and 24/7 reliability.
03
Multi-Sludge Ready
Proven performance for Municipal, Food & Beverage, Chemical, and Oily Sludge applications.
The R+F Dewatering Principle
A fully enclosed, low-speed system engineered for high-performance solids separation.
Flocculation Zone
Precision polymer dosing creates a stable floc structure. This chemical conditioning is the foundation for a maximized capture rate and crystal-clear filtrate.
Thickening Zone
Initial gravity drainage removes the bulk of free water. The sludge volume is rapidly reduced before entering the high-pressure zone, optimizing throughput.
Seamless Plug & Play
Designed with a compact footprint for easy integration into existing plants. Our fully automated control systems (PLC) ensure a 'set and forget' operation with minimal supervision required by your staff.
Precision Engineering for Maximum Separation
The R+F Multi-Disk Principle
At the core of our screw press series lies a sophisticated multi-disk filter drum. By combining fixed and moving rings with a variable-pitch screw, the system creates increasing pressure as the sludge moves toward the discharge zone.
This dynamic filtration process prevents clogging and ensures a continuous, self-cleaning operation. The result is a highly stable dewatering performance with minimal wash-water consumption and superior filtrate clarity.
