MBR Sizing Calculator
Use this interactive tool to calculate key design parameters for your MBR system. Enter your wastewater flow and treatment objectives to estimate tank volume, membrane area, and operational parameters.
📊 Input Parameters
m³/day (cubic meters per day)
Ratio of peak to average flow (typically 1.5–2.0)
L/(m²·h) – typical range 15–30 for UF membranes
days – longer SRT improves nitrification
mg/L – mixed liquor suspended solids concentration
mg/L – biochemical oxygen demand
hours – time wastewater spends in bioreactor

💡 How to Use This Calculator
This calculator provides preliminary sizing estimates based on standard MBR design principles. The results are useful for feasibility studies and initial design phases. For detailed engineering, consult with experienced MBR designers and verify assumptions with site-specific data. Key parameters like flux, SRT, and MLSS should be adjusted based on your specific wastewater characteristics and effluent quality requirements.
