The vertical flow hydraulic flocculator has been used to test tapered and uniform baffle configurations during previous semesters, but the two configurations have never been compared with similar raw water conditions. For this reason the Fall 2008 Pilot Plant team plans to repeat testing with the two configurations. We plan to develop turbidity profilesturbidity profiles that are comparable for both configurations. This data will enable us to determine whether or not tapered flocculation is more efficient than uniform flocculation as has been suspected in past semesters.
