Water tools
Water treatment calculators
Fast, free calculators for the numbers engineers reach for daily. Every one uses a standard published formula, shown with its assumptions, so you can trust the result and check it.
TDS to Conductivity Converter
Convert electrical conductivity (µS/cm) to total dissolved solids (mg/L) and back, with a factor for brackish, mixed, or seawater.
Cooling Tower Blowdown & Cycles
Estimate evaporation, blowdown, and make-up water from recirculation, temperature range, and cycles of concentration — and the water saved by higher cycles.
Langelier Saturation Index (LSI)
Will cooling, boiler, or process water scale or corrode? Enter pH, temperature, TDS, calcium, and alkalinity for the LSI and its interpretation.
