Find the right calculator for the questions our specialists field weekly — pipe sizing, storage capacity, electrical conversions and water-quality checks. Sensible defaults, every field editable, every output in the units you work in.
Standard SAC (strong-acid cation) softener sizing. Translates daily water demand, raw water hardness and the chosen regeneration interval into litres of resin, daily salt usage, total regen water waste and an implied salt dose vs salt-efficiency profile — the four numbers a procurement officer needs to specify a softener and budget its lifetime running cost.
Sanity checks every output against the industry 8 – 40 BV/h service rate band, the 80 – 240 g NaCl / L resin salt-dose band, and reports the sodium added to product water against the SANS 241 dietary limit.
Used by lodge engineers comparing softener bids, municipal water-quality engineers planning regen-effluent disposal, and procurement officers building 10-year salt and waste-water cost forecasts.
The Water softening resin sizing workflow is reserved for verified engineering and procurement contacts. We open it on request — typically within one working day — so each user is on file with us and gets useful follow-up if their numbers flag something we can help with.
