Choosing the correct screw press sludge dewatering machine starts with one key number:
Dry solids capacity (kgDS/h).
All screw press models are selected based on this parameter. Once you know your required kgDS/h, the right model can be determined quickly.
Simple Selection Formula
Daily wastewater flow (m³/day) × sludge yield (kgDS/m³) ÷ operating hours (h/day) = required kgDS/h
Example
10,000 m³/day × 0.8 kgDS/m³ ÷ 20 h/day = 400 kgDS/h
In this case, select a screw press with capacity slightly above 400 kgDS/h.
We recommend reserving 20–30% extra capacity for stable operation.
What Information Do We Need?
You can send us any of the following:
①Required dry solids capacity (kgDS/h)
②Sludge flow rate and concentration
③Existing sludge cake output (T/day)
④Daily wastewater treatment capacity
Our engineers will calculate the correct screw press sludge dewatering equipment model for you.
Why Proper Screw Press Selection Matters
Correct sizing ensures:
①Stable sludge dewatering performance
②Lower polymer consumption
③Reduced energy cost
④Longer equipment lifespan
⑤Avoidance of overload or overspending
Undersized machines cause operational problems.
Oversized machines increase investment cost.
Proper selection protects your project.
