Calculators · Beta
Plant chemistry math, on the back of an envelope.
Three free chemistry calculators that procurement officers and process engineers reach for week-to-week: feedwater scaling vs corrosive tendency (LSI / Ryznar), monthly chemistry consumption + cost band, and vendor cost-in-use head-to-head. All three are in beta — results are indicative, not binding. For production decisions, calibrate against on-site lab analysis and request a feedwater audit.
Beta notice: chemistry math reviewed against published Langelier / Ryznar / cost-in-use formulas (Larson-Buswell variant; AWWA M46 convention). Awaiting principal spot-check before broad promotion. Send issues / disagreements to info@austinandersonsolutions.com.
Beta Calculator
Langelier + Ryznar Stability Index
LSI / RSI Calculator
Compute scaling vs corrosive tendency on your feedwater. Closed-form Larson-Buswell variant of Langelier (1936) + Ryznar (1944). Beta — for indicative reference; verify with site lab analysis.

Monthly chemistry consumption + cost band
Chemistry Dosing Calculator
Pick a chemistry, set your flow rate, dial the dose within product spec — get monthly consumption (kg) and indicative PKR cost band. Pulls dose ranges from AAS product specs.

Head-to-head vendor comparison
Cost-in-Use Comparator
Compare two vendors on cost per m³ treated + cost per kg active species. Normalises against active concentration — the only fair head-to-head. Anchors the China-Pakistan corridor moat.

Beyond the calculator
For sized programmes — we run a feedwater audit.
Calculators answer "what's the dose?" An audit answers "what's the programme?" — full feedwater characterisation, scaling-index profile across feed and concentrate, vendor cost-in-use vs incumbent, and a 3-year supply continuity plan via the China-Pakistan corridor. Engineered, not estimated.
