DAF Sludge Case Study
Dewatering high-FOG DAF float sludge
Representative Project Profile
The following describes a representative application scenario for a screw press in this sector, based on typical process data and equipment configurations. It illustrates how a solution is scoped — final performance is always confirmed with your actual sludge.
The Challenge
A site with a DAF unit struggled to dewater greasy float sludge that blinded conventional equipment and required tankering off-site at high cost.
The Solution
A multi-disc screw press with polymer conditioning dewatered the DAF float on site, cutting transport volume dramatically. The self-cleaning gap handled FOG without blinding.
Typical Results
| Parameter | Value |
|---|---|
| Sludge type | DAF float |
| FOG | Very high |
| Cake DS | 15–20% |
| Benefit | Major transport reduction |
