In treated waters alkalinity may also be contributed by hydroxide phosphate silicate and.
Boiler water hardness test procedure.
Take test sample for.
Follow test procedures recommended by unitor chemical services water quality analyzer spectrapak 311.
To exercise careful control over boiler treatment chemicals.
The rain water catches co2 from the atmosphere when the water pass through caco3 rock in the soil these compounds make the water hard.
Calcium and magnesium chlorides.
Hard water is generally considered to be one which requires considerable amount of soap to produce foam or leather.
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.
1 ph 2 alkalinity 3 chlorides 4 phosphates 5 total hardness.
For economical operation of boiler.
Hard water cause scale formation in boilers heaters and hot water pipes.
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.
