)—instantly updates the entire downstream hydraulic and process design.

Use Excel's built-in Data Validation tool to restrict inputs to realistic engineering bounds. Prevent errors by flagging entries like negative flow rates or impossible A high-quality Excel calculation sheet serves as the

Assume an average daily flow (Q_avg) of 10,000 m³/day. Peak factor (PF) often follows the Harmon formula or local standards.

Required Surface Area (A) = Q_peak / SOR = A1/A2 = 625 m² If using two tanks: Area per tank = 312.5 m² Diameter per tank = SQRT(312.5/(PI()/4)) = ~20 m Use Excel's built-in Data Validation tool to restrict

Mass balance must account for every kilogram of solids generated in the primary and secondary stages.
