Methods for Alkalinity Calculator
Gran's method can be used to quantify negative values of alkalinity in solutions with an initial pH lower than the bicarbonate equivalence point. It is the only method available in the Alkalinity Calculator that can do so.
Alkalinity is a measure of an aggregate property of water and can be interpreted in terms of specific substances only when the chemical composition of the sample is known. Alkalinity is significant in many uses and treatments of natural waters and wastewaters.
As we can see from the illustration, Alkalinity Adjustment Method has many fascinating aspects to explore.
Unlike general pH correction, pH adjustment in water treatment involves not only measuring acidity or alkalinity , but also choosing the right chemical to maintain consistent results. That's where alkalinity adjusters like magnesium hydroxide, lime slurry, soda ash, and caustic soda come into play.
Alkalinity of filtered water is often adjusted to control its corrosivity prior to release in the distribution system and measuring alkalinity of the tap water in the distribution network is important to ensure adequate corrosion control and avoid violation of the lead and copper rule (LCR).
This particular example perfectly highlights why Alkalinity Adjustment Method is so captivating.
PDF 6.6 Alkalinity and Acid Neutralizing Capacity
Alkalinity , ANC, and concentrations of bicarbonate, carbonate, and hydroxide species are most commonly determined by analyzing acidimetric-titration data with either the inflection point titration method (section 6.6.4.B) or the Gran function plot method (section 6.6.4.C).
The change in pH and resulting increase in color is proportional to the alkalinity of the sample and is measured at a specific wavelength (e.g., T-alkalinity at 610 nm and P-alkalinity at 560 nm).
