The interpreter maps a lab report onto trains Envora actually builds: drinking-water plants (screening → coagulation–flocculation → lamella/settling → sand/multimedia → carbon → Fe/Mn → softening → UF → RO → disinfection) and wastewater plants (equalization → DAF → physchem → activated sludge or MBR → filtration → RO reuse if needed).
Sample type (well, surface, boiler feed, cooling, wastewater) and target (potable/process, boiler, cooling, discharge, reuse) change which stages are shortlisted. Alkalinity, silica, free chlorine, ammonium, phosphate, aluminium, SDI and trace contaminants (As in µg/L, F, B, Pb/Cr/Ni, Ba, H₂S) are optional; blanks are ignored.
Thresholds are conservative WHO / TS 266-inspired guides plus industrial membrane practice — not a legal discharge or potable licence. A Langelier-like scaling/corrosion hint is produced only when pH, alkalinity, hardness and TDS are all present; missing alkalinity is stated, not faked.
Who is it for?
Process and plant engineers, feasibility teams and investor advisors with a partial analysis who need a first look at an Envora drinking-water, wastewater, desalination or reuse train.
How it works
Choose sample type and target. Use report units (mg/L, NTU, dimensionless pH and SDI, EC in µS/cm). Leave unknowns blank. Calculate returns KPI tiles, a guide-threshold table, an ordered Envora train, risk notes and links to RO, dosing, tank and the wastewater selector.
Assumptions and limits
Thresholds are guidance (WHO/TS 266 and conservative membrane practice); legal limits vary by site. Qualitative LSI uses total hardness as a Ca²⁺ proxy when calcium is missing, and says so. No jar test, speciation, SDI column or membrane projection. The output is not a quotation.
