Thickener vs. Clarifier What's the Difference? McLanahan

Clarifier or Thickener? It can be tempting to try to do both the thickening and clarifying functions to maximum benefit in one go. While technically this is feasible, youd need a really large diameter (for low rise rate and good clarity), yet tall tank with higher side walls and a robust drive and rake mechanism.
