Conversion of caco3 equivalent, Chemistry

Assignment Help:

Q. A sample of water analysis was found to contain temporary magnesium hardness 25 mg/L. Permanent magnesium chloride hardness 15 mg/L and permanent calcium sulphate hardness 20 mg/L, SiO2  = 30kg/L. Calculate the lime and soda required for softening 30,000 litters hard water.

Ans.

Conversion of CaCO3 equivalent

constituent

amount

Multiplication factor

CaCO3 equivalent

Mg(HCO3)2

25 mg/L

100/146

25*100/146=17.12 mg/L

MgCl2

15mg/L

100/95

15*100/95=15.72mg/L

CaSo4

20mg/L

100/136

20*100/136=14.7mg/L

 

 

 

 

SiO2 do not required Lime soda.

Lime required = 74/100(Temp. hardness + Perm. Hardness) = 74/100(17.12 + 15.12) = 24.30 mg/L

Lime required for 30000 Litre hard water = 24.30*30000 = 729 mg

Soda required = 106/100(perm. Ca hardness + perm. Mg hardness) = 106/100(15.72 + 14.70) = 32.24 mg/l

Soda required for 30000 litre hard water = 32.24 mg/λ*30000λ = 967.2 mg
