Work out ph adjustment chemical dose instantly with clear inputs, formula shown and shareable results.
pH adjustment dose depends far more on buffering capacity than on the pH change itself. A poorly buffered soft water shifts pH with a very small dose, while a highly alkaline water resists change. The dose must be established by titration on the actual water and verified by continuous pH monitoring.
Dose estimate
Dose (mg/L) proportional to pH change x buffering factor, with buffering factor = 1 + alkalinity / 50
pH correction affects lead and copper release from plumbing and is a regulated corrosion control measure. Acid and caustic chemicals are hazardous and require containment and dosing safeguards.
To control corrosion and metal release in the distribution system, to optimise coagulation and disinfection, and to meet the regulatory pH range. Under-corrected soft water dissolves lead and copper from plumbing.
A saturation index indicating whether water will deposit or dissolve calcium carbonate. Corrosion control aims for slightly positive saturation so a protective scale forms without excessive deposition.
