Online water treatment calculators
Industry-standard online estimators built for plant process engineers, operators and procurement teams to support chemical selection, annual budgeting and proposal discussions.
Cooling Water Calculator
Enter make-up water quality and system parameters (recirculation rate, cycles of concentration, annual operating hours). The tool applies the international mass-balance (COC) method together with the Langelier (LSI) and Ryznar (RSI) indices to estimate annual scale & corrosion inhibitor and biocide usage and recommend POLYTE® codes.

RO Antiscalant Calculator
Enter feed ions, recovery and concentration polarisation to estimate concentrate SDSI, gypsum / barite / celestite / CaF₂ saturation ratios and a silica solubility ratio, then obtain rule-based TRISPE® picks. Optional feed flow estimates annual dose.
