What is the unit of alkalinity?
Alkalinity is a measure of the presence of bicarbonate, carbonate or hydroxide constituents.
Concentrations less than 100 ppm are desirable for domestic water supplies.
The recommended range for drinking water is 30 to 400 ppm.How do you calculate alkalinity?
The unit of measurement for alkalinity is mg/L CaC03.
What is the significance of alkalinity? Alkalinity is the measure of the resistance of water to the lowering of pH when acids are added to the water.
Acid additions generally come from rain or snow, though soil sources are also important in some areas.
