Decanters Reduce Kentucky WWTP's Hauling and Operational Costs

Problem: The Dry Creek Wastewater Treatment Plant in Erlanger, Kentucky, treats 46.5 mgd. High solids content in biosolids after centrifuging is critical to minimizing hauling and landfill costs.

Solution: After an analysis of alternatives, the facility management team chose three decanter centrifuges from Flottweg Separation Technology.

Result: The resulting cake at 30% solid instead of 16% meant 47% less hauling cost. The facility also cut its dewatering equipment footprint in half and stabilized electricity costs. 859-448-2331; www.flottweg.com
