Overview
Struggling with clogged filter presses, high energy consumption, and the inability to handle oily sludge? Our professional-design Dewatering Screw Press is the ultimate upgrade for modern wastewater treatment. It utilizes advanced dewatering principles including force-water homo-direction, thin-layer dewatering, proper pressure, and the extension of the sludge dewatering path.
Compared to traditional dewatering equipment that is easily blocked and difficult to operate, our screw press eliminates these headaches. It is specifically designed to handle low-concentrated and oily sludge with higher efficiency and significant power savings.
How It Works (Core Principles)
- Gravity Concentration (Gravity Zone): As the spiral blade (screw shaft) rotates, the multiple moving and fixed rings around the shaft shift relative to each other. Free water filters out through the gaps under gravity, achieving rapid concentration.
- Continuous Dewatering (Pressure Zone): The thickened sludge moves forward along the screw. The pitch of the spiral blade gradually decreases towards the discharge end, shrinking the cavity volume. Combined with the resistance from the back pressure plate, the internal pressure increases, continuously squeezing out moisture to produce a high-solid filter cake.
- 100% Self-Cleaning Mechanism: The rotation of the screw continuously drives the moving rings. This constant movement between the fixed and moving rings creates a continuous self-cleaning process, brilliantly avoiding the severe clogging issues common in traditional presses.
Key Features & Advantages
- Direct Low-Con Dewatering: Capable of processing low-concentration sludge (from 2000mg/L) directly. No need to build separate thickening or storage tanks, dramatically reducing civil construction costs and preventing anaerobic odors.
- Perfect for Oily Sludge: Highly effective at separating water from oily and sticky sludge without blinding the filter mesh.
- Automated & User-Friendly: Equipped with an intelligent Control Panel, Mixing Motor, and automatic wash system (Water Gun), allowing for 24/7 unattended, continuous operation.
- Energy & Water Saving: Operates at a low speed, consuming a fraction of the power of centrifuges and requiring minimal wash water compared to belt presses.
