Case Studies
Municipal WWTP Case Study
Unattended dewatering of mixed municipal 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 mid-sized municipal plant needed to replace an ageing belt press that required constant operator attention and generated odour and wash-water issues. Peak flows and night-time operation without staff were key constraints.
The Solution
A screw press sized for mixed primary/WAS sludge was installed with automatic polymer dosing and remote monitoring. The enclosed design contained odour, and continuous unattended operation absorbed peak flows overnight.
Typical Results
| Parameter | Value |
|---|---|
| Sludge type | Mixed primary + WAS |
| Feed DS | ~2–3% |
| Cake DS | 18–22% |
| Operation | 24/7 unattended |
| Energy | Very low vs. belt press |
