What This Module Helps You Design
Use one consistent engineering workflow to size a two-stage vertical turbine flocculator. The workbook brings detention time, basin sizing, tapered G/Gt evaluation, mixing power, motor power, impeller geometry, rotational speed, tip-speed checks, and design compliance together in one module.
Tapered Mixing Review
Evaluate target G, actual G, stage Gt, total Gt, and average velocity gradient.
Mixer Design Checks
Screen axial-flow impellers and review shaft speed, D/T, H/D, H/T, B/D, and tip speed.
Calculation Coverage
Preliminary vertical turbine flocculator sizing and review from design input through basin geometry, mixer-duty distribution, impeller screening, and design compliance.
Design Basis
Flow rate, detention time, temperature, and selected staged mixing parameters.
System Layout
Two basins in series with one mixer per basin and tapered mixing intensity.
Basin Sizing
Volume per basin, plan area, basin length, width, and total internal depth.
Mixing Intensity
Target and actual G values for Basin 1 and Basin 2 with tapered duty.
Gt Evaluation
Stage Gt, total Gt, and average velocity-gradient review.
Mixing & Motor Power
Calculate required power input and total motor power per stage.
Impeller Screening
Automatic axial-flow impeller screening with selected diameter and power number.
Rotational Speed
Calculate shaft speed and mixer tip speed for both stages.
Design Compliance
Check D/T, H/D, H/T, B/D, tip speed, and overall PASS / REVIEW status.

Protected methodology
The public preview shows the review structure without disclosing the complete product equations or internal criteria set.
Designed for Engineering Review
A flocculator calculation should make the basin arrangement, mixer duty, and review logic easy to follow.
