Optimisation of clarifier-thickeners processing stable suspensions for turn-up/turn-down.


Solid-liquid separation equipment operating on wastewater duties seldom functions at steady state and may be expected to perform over a wide range of feed loads. Satisfactory control of the solids residence time in these clarifiers and thickeners is critical to their successful operation. High solids residence times can lead to hydrolysis and rising sludge… (More)
