Coagulation and Flocculation books.

(OP)
I am looking for a good book, reasonably priced on coagulation and flocculation. I am treating ground water and doing coag/Floc/Sedimentation all in the same basin.

RE: Coagulation and Flocculation books.

I can not understant how you do coagulation in the same basin. I guess you flash mix before the basin. Anyway, you can find also a lot of details on the subject at:

1)A.W.W.A. Research Foundation, (1991), Mixing in Coagulation and Flocculation, Amirtharajah, A., Clark, M. M. and Trussell, R. R. (eds).

2)Montgomery, J. M. J., (1976), Water Treatment Principles and Design, John Wiley and Sons Inc., USA, pp. 696.

3)Armitharajah, A., (1978), Design of rapid mixers, In Water Treatment, Principles and Practices of Water Supply Operations, AWWA, Denver, Colo, USA.

And remember the use of the G value as a mixing control parameter has been strongly questioned by numerous researchers:

Clark, M. M., (1986), Critique of Camp and Stein’s velocity gradient, Journal of Environmental Engineering, A.S.C.E., 110, 741.
Cleasby, J. L., (1984), Is velocity gradient a valid turbulent flocculation parameter?, Journal of Environmental Engineering, A.S.C.E., 110, 875.

In the center of our sedimentation basin/clarifier there is a rotating cone with a mixing blade inside. Alum and lime is added right at the influent pipe to the tank just after the aerator and polymer and chlorine are added directly into the cone. The raw water/chemicals are flashed mixed in the cone and slows down as the water leaves the cone and enters the basin.
