Microfloc Adsorption Clarifier Improves Effluent Filter Turbidity, Filter Run Time, and Net Production at the Huntsville WTP

The Huntsville Water Treatment Plant is supplied by the 25 foot deep Huntsville Reservoir and is operated by Pennsylvania American Water.  The facility was originally constructed with four heavy media up-flow clarifiers.  The clarifiers were fitted in a concrete basin and fed four media beds.  The reservoir; which is a reserve,  supplies a stable supply and typically exhibits a seasonal algae plume in the summer.  The facility was only observing minor reductions in turbidity and was experiencing maintenance problems with instrumentation and physical restraints caused by “fines” from the clarifier. 

In contrast, the nearby Ceasetown WTP facility was equipped with a Microfloc Adsorption Clarifier®.  Though both facilities were designed to utilize air scour during the clarifier cleaning or flushing sequence, the Ceastown facility was seeing a 60% reduction in turbidity without the maintenance or physical restraint issues. 

After comparing the performance at the two facilities it was anticipated that longer filter bed run times, improved functional performance and lower maintenance costs could be achieved by converting the Huntsville facility to the Microfloc technology.
