Screw Press Operating Cost
Why screw presses have exceptionally low running cost
Operating Cost Drivers
Operating cost (OPEX) accumulates every hour the machine runs. Screw presses are known for very low OPEX: they draw little power (often below a few kW), run unattended, use minimal wash water, and have few wear parts. Polymer is usually the largest single running cost, followed by disposal, which is driven by cake dryness.
Typical OPEX Elements
| Element | Screw Press Characteristic |
|---|---|
| Energy | Very low — often < 5 kW |
| Polymer | Optimised by flocculation design |
| Wash water | Intermittent, minimal |
| Labour | Minimal — unattended operation |
| Maintenance | Low — few wear parts |
| Disposal | Reduced by drier cake |
