Clarification System Boosts Capacity, Reduces Maintenance
Spikes in peak demand at the 3.0 MGD Freedom District Water Treatment Plant in Carroll County, MD, exceeded 70 percent of the plant’s capacity, and the existing clarifier made for a lengthy sludge-removal process. After staff installed a dissolved air flotation (DAF) pretreatment system to improve the efficiency of the membrane filters, the now 4.0 MGD facility has reduced maintenance for operators. The system also safeguards against pathogens that can pass through traditional sand/diatomaceous (S/D) filters.
