Question

1)If the water concentration is reduced from 25 mg/L of phenol to a concentration of 0.10 mg/L, what is the adsorption capacity of the PAC?

 

2)Given all the conditions in the problem and given a flowrate of 0.11 cubic meter per second, what is the quantity, in kg, of PAC needed per day (24 hours) of operation?

A water containing 25 mg/L of phenol is to be reduced using PAC to a
concentration of 0.10 mg/L. The PAC is added to the stream and the mixture
subsequently settled in a sedimentation tank. The constants of Langmuir
Equation are determined by running a jar test producing the results shown in the
table. The volume subject to each test is 1 Liter. *
