| Tab Name | Purpose | | :--- | :--- | | | Raw influent characteristics (BOD, COD, TSS, TKN, Flow) and effluent permit limits. | | Design_Criteria | Key design parameters (SRT, HRT, F/M ratio, temperature, safety factors). | | Primary_Treatment | Screening, grit removal, primary clarifier sizing. | | Secondary_Treatment | Activated sludge basin volume, aeration requirements, return sludge rate. | | Final_Clarifier | Surface overflow rate (SOR), solids loading rate (SLR), weir loading. | | Sludge_Handling | Thickening, digestion, dewatering volume and mass balances. | | Hydraulics | Headloss through each unit, pump sizing. | | Summary_Tables | Equipment schedule, tank dimensions, blower power, chemical dosing. |

: These were her "inputs"—the variables she could control, like the influent flow rate ( Qocap Q sub o ) and biochemical oxygen demand ( Socap S sub o

: Offers specific sheets for Moving Bed Biofilm Reactors (MBBR) and BOD removal/nitrification.
