01 · FLOW AND PROJECT BASIS
Design flow cases
Maximum Day and Peak Hour provenance
Bounded event / batch
02 · NEUTRALIZATION BASIS
Chemical demand requires a defined equivalent basis
03 · COAGULATION / FLOCCULATION
Use declared test, vendor, or project doses
Declared mix / flocculation HRT
V = Q × t · no universal HRT is assumed.04 · CHEMICAL PRECIPITATION
Choose explicit reaction or declared dose authority
Optional reaction/contact volume
Declared flow and HRT only.05 · MODELED CONSTITUENT BALANCE
Preserve constituent identity, sample basis and provenance
Enter concentrations in mg/L or mg/L as P as identified. A case requires a paired flow before any mass load is calculated. “No removal declared” is pass-through component accounting only.

Maximum Day is a design-day quantity. Peak Hour is actual kg/h (and may show separately labelled kg/d-equivalent); Event is kg/event. Average daily use is not annualized without an operating-days basis.
Manual feed package handoff: Chemical Feed & Storage Designer owns storage, day-tank, feed-pump redundancy, and turndown sizing.
07 · MODELED COMPONENT CLOSURE
Declared influent, captured, and remaining liquid mass

PHYSICOCHEMICAL_SLUDGE_BASIS is distinct from PRIMARY_SLUDGE, BIOLOGICAL_WAS, SCREENINGS, and GRIT. Precipitated target mass is informational when included in reaction-product solids.

Engineering Basis
Assumptions
- Supports explicit neutralization methods, declared coagulation/flocculation dose and HRT, a bounded FeCl₃-to-orthophosphate-P stoichiometric case or declared reagent ratios, constituent closure, chemical solids, and manual clarifier or vendor separation handoffs. It does not predict an optimum dose, chemical speciation, removal performance, toxicity, biodegradability, regulatory compliance, DAF sizing, or chemical storage/feed equipment.
Scope / Limitations
- Supports explicit neutralization methods, declared coagulation/flocculation dose and HRT, a bounded FeCl₃-to-orthophosphate-P stoichiometric case or declared reagent ratios, constituent closure, chemical solids, and manual clarifier or vendor separation handoffs. It does not predict an optimum dose, chemical speciation, removal performance, toxicity, biodegradability, regulatory compliance, DAF sizing, or chemical storage/feed equipment.
