How to Calculate Wedge Wire Screen Flow Rate
When calculating flow rate through a wedge wire screen, the method depends on:
✅ Gravity flow or pressure flow
✅ Internal feed or external feed
✅ Slot opening size
✅ Open area percentage
✅ Liquid viscosity
✅ Head loss / pressure drop
Below is the practical industrial calculation method used for rotary drum screens, static screens, and wedge wire cylinders.
Basic Flow Formula (Liquid Through Slots)
How to Calculate Effective Open Area
Example Calculation (Industrial Wastewater)
This is theoretical clean water capacity.
Real operating flow is typically 30–50% lower due to:
Partial clogging
Solids loading
Uneven distribution
Fouling
Head loss variation
So realistic design flow:
≈1,500–2,000 m3/h
Gravity Flow (Static Screen)
Rotary Drum Screen Capacity Formula (Practical)
Key Design Factors
Flow rate depends heavily on:
Slot opening (0.25–3 mm common)
Open area %
Wire profile (V-shape reduces clogging)
Material (304 / 316L)
Internal vs external feed
Solids concentration

Wedge Wire Screen Flow Rate FAQ
How do you calculate wedge wire screen flow rate?
Wedge wire screen flow rate can be estimated using Q = A × V, where Q is flow rate, A is effective open area, and V is approach velocity.
What is the typical velocity through a wedge wire screen?
Typical approach velocity ranges from 0.3 to 0.6 m/s for wastewater applications.
What factors influence wedge wire screen flow capacity?
Flow capacity depends on slot width, wire profile, open area percentage, screen surface area, head loss, and solids concentration.
What safety factor should be used in screen sizing?
Engineers usually apply a safety factor of 20% to 50% to prevent clogging and handle peak flow conditions.
