The King County South Treatment Plant in Renton,
Washington, has found monitoring the solids loading
to the dissolved air flotation thickener (DAFT) tanks
yields the timely signal needed for effective control
of polymer dosing during sludge thickening (THS).
The trick, according to Curtis Steinke, Process
Analyst at the Renton plant, was to find a suspended
solids sensor that stands up to the task in such a
harsh environment. He found his answer at work in
another process at the same plant.
