Retrofit Case Study
Replacing legacy dewatering with a screw press
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
An operator faced rising maintenance and energy cost from an old dewatering machine and wanted to modernise within the existing building and connections.
The Solution
A screw press was retrofitted into the existing footprint, reusing feed, polymer and cake-handling connections where possible. Energy and labour dropped sharply while cake quality was maintained.
Typical Results
| Parameter | Value |
|---|---|
| Scope | Retrofit in existing building |
| Energy | Sharply reduced |
| Labour | Reduced |
