A softeningplant is to be desin gned to treat water having a hardness
of 160 mg/L as CACO,. This hard water entersthe Rapid Mix
( onecompartme) at a flow rate of 0.15 m/s. A hydroxides dose
is addedto react with Mg*2 and Ca*2 cationsand non carbonates
Water is wantedto leavethe Rapid Mix with a hardnessof 120 mg L
as CaCO,. Assum&hat theUnit Mix satisfiesC.S.T.R, and the
softeningreaction is first order with a rate constant of k, = 0.02 s.
The outlet water froma Rapid Mix entersa Flocculaton Basin and is to
be treated to give softwater at 80 mg| L as CaC, .
