Andritz - Model C-Press - Efficient Sludge Dewatering Screw Press
From Screens, Drains, and Presses
The C-Press is the latest result of more than 20 years of experience in designing and manufacturing screw presses. By combining multiple ANDRITZ SEPARATION dewatering technologies, its uniquely compact design and its purpose developed features enables easy, operator-free sludge dewatering together with low energy and maintenance costs.
High-Performance System
Maximizing the open area of the basket, the C-Press offers a high specific capacity and capture rate compared to equivalent technologies. The screw velocity is adjusted automatically according to feed fluctuation to ensure a constant feed flow while delivering optimal performance in terms of dryness and capture rate, even during washing sequences.
Operating Principle
The flocculated product is fed into the screw press, where it is thickened and compressed gradually along the length of the machine. A screw conveys the product through the machine at low speed (0.1 to 1 rpm), and the conical screw shaft makes it possible to increase pressure gradually. A pneumatic counter-pressure device prevents the product from moving too quickly, squeezing the product and achieving maximum possible dryness.
The screw speed is adjusted continuously and automatically to maintain a constant feed pressure, while a dual cleaning device cleans the thickening and squeezing zones separately from time to time to ensure constant dewatering efficiency while reducing water consumption by up to 50%.
