Food Industry Case Study
Dewatering greasy, high-organic food 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 food processor generated DAF float and biological sludge with high fat, oil and grease that rapidly blinded cloth-based dewatering equipment, driving up wash water and downtime.
The Solution
A multi-disc screw press was applied for its self-cleaning filtration gap, which resists FOG blinding. Continuous operation and low wash-water demand cut operating cost and eliminated cloth handling.
Typical Results
| Parameter | Value |
|---|---|
| Sludge type | DAF float + biological |
| FOG | High |
| Cake DS | 16–22% |
| Wash water | Low |
