This method is used to calculate hardness based on concentration of divalent ions in water such as ca 2 mg 2 and sr 2 calculation of hardness based on concentration of divalent ions can be calculated by using following equation.
Boiler water hardness test procedure.
Alkalinity test in natural waters alkalinity is most commonly the result of bicarbonate and carbonate ions.
1 ph 2 alkalinity 3 chlorides 4 phosphates 5 total hardness.
Calcium and magnesium chlorides.
Hard water cause scale formation in boilers heaters and hot water pipes.
Follow test procedures recommended by unitor chemical services water quality analyzer spectrapak 311.
The rain water catches co2 from the atmosphere when the water pass through caco3 rock in the soil these compounds make the water hard.
In treated waters alkalinity may also be contributed by hydroxide phosphate silicate and.
To exercise careful control over boiler treatment chemicals.
All the boiler water test kits come with a standardized step by step test procedure for various boiler water tests.
Let the water over flow from the sample bottle to prevent air being trapped inside the bottle and keeping the bottle air tight for testing.
A boiler that makes up 4000 gal day of water having 100 ppm of hardness has a potential of accumulating over 1000 pounds of scale per year.
To improve efficiency thus increasing boiler life.
