04 · CHEMICAL PRECIPITATION

Choose explicit reaction or declared dose authority

Stoichiometric reagent availability does not guarantee complete precipitation.

Precipitation method Declared removal target

Defined reactionFeCl₃ + PO₄³⁻ → FePO₄(s) + 3 Cl⁻Orthophosphate target is expressed as mg/L as P. Stoichiometry applies only to the declared captured P mass; no equilibrium/speciation or removal prediction.

Optional reaction/contact volume

Declared flow and HRT only.

05 · MODELED CONSTITUENT BALANCE

Preserve constituent identity, sample basis and provenance

No default removal percentages; each declared capture is separate from reagent mass.

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.

06 · CHEMICAL DEMAND

Average, maximum-day, peak-feed, and event quantities

No peak-hour or event annualization.

Chemical feed package by explicit flow case

Flow case / chemical	Active dose	Active demand	Peak-equivalent basis	Product mass	Product volume	Basis
Calculate to populate this result table.

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

Not a whole-plant mass balance; chemical reagent is an added mass term.
