Tapered vs. Uniform Baffle Configuration
Introduction
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 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.
Methods
Results
Several tests have been run with the uniform baffle configuration. The initial results were inaccurate due to a clog in the inlet valve of the raw water sampling line.
The accuracy of this result is questionable. The tank had to be cleaned before the measurement could be taken. Cleaning may have increased turbidity in the last section of the flocculator.
