Abstract
Batch tests were
conducted using four groundwater samples which showed high levels of total
hardness such as 600, 800., 1088. and 1278.38 mg/L as CaCO3, so
water is not suitable for several industries. The present work aimed to
evaluate the feasibility of using powdered pseudoactivated carbon (PAC)
prepared from wheat husk of Agra City of U.P. (India) for the removal of water
hardness and also to study of impact of sodium dodecyl sulphate (SDS) micelles
on the removal. The ability of 0.05, 0.1, 0.5, 1.0 and 5.0 g/L PAC to soften a
water was investigated by shaking 50 mL hard water with PAC at pH 5.0 and 25ºC
for 180 minutes. The effect of SDS was studied by running parallel tests with 10
mL of 3 g/L SDS solution. Equilibrium was attained within 2 hours with PAC and
1.25 hours with PAC + SDS. The maximum removal was found 27.8 % with 5 g/L PAC
at pH 5, 25oC for 600.17 mg/L hardness. With PAC + SDS the removal was enhanced
to 81.1 % with 10 mL of 3 g/L SDS and 5 g/L of PAC for the same.
