Stop Fighting with Open Filter Presses: Why It’s Time to Switch to Automated Volute Dewatering
For plant managers in food processing, abattoirs, chemical refining, and municipal wastewater, sludge handling is often the most dreaded part of the day. Traditional plate-and-frame or belt filter presses come with a heavy toll: foul odors escaping into the workshop, blinding filter cloths that require constant manual washing, and unsafe work environments.
If your facility is still treating sludge with outdated, open dewatering systems, you are losing time, labor, and money.
The Modern Alternative: Enclosed, 24/7 Automated Operation
The Smart Volute Sludge Dewatering Press from HNS Watertech is engineered to replace high-maintenance filtration systems with a clean, fully enclosed, and continuous solution. By combining a fixed-and-moving ring filtering structure with a slowly rotating screw shaft, it achieves continuous thickening and pressing without the hassle.
Here is how upgrading to a Volute Press transforms your facility’s operations:
- Odors Kept Inside: The fully enclosed structure ensures that irritating smells and biological pathogens stay contained. Your operators get a clean, odor-free workspace.
- No More Blinding or Manual Washing: The self-cleaning mechanism prevents clogging, meaning the system doesn’t require massive amounts of high-pressure water for backwashing. It easily handles sticky, organic, and oily sludge (such as dairy, abattoir, or food waste) that would instantly blind a standard filter cloth.
- True “Set-and-Forget” Automation: Built for unmanned operation, the system controls everything—from polymer dosing to cake discharge—automatically.
- Automatic Flushing: Programmable timers rinse the unit automatically.
- Continuous Discharge: Sludge is fed in and dry cake rolls out 24/7 without manual intervention.
- Zero Attendance Needed: Frees up your engineering team to focus on high-value tasks, cutting labor costs dramatically.
In-House Manufacturing Meets Complete Scalability
At HNS Watertech, we don’t just assemble machinery; we control the quality from the ground up. Our production facility handles core component manufacturing in-house—including laser cutting, screw shaft welding, and stress-relief processing—allowing us to offer premium commercial reliability alongside competitive pricing.
We offer more than 20 models to fit any plant layout or flow rate, ranging from compact units processing small batches hourly to heavy-duty skids for large industrial plants. For example, our mid-sized models easily fit into tight dewatering rooms with small footprints while continuously processing cubic meters of slurry daily.
