Fast-Track Design for Regulatory Compliance at the 285-MGD Potomac WFP Client: Washington Suburban Sanitary Commission Location: Laurel, MD Hazen and Sawyer was selected to analyze the impacts of coagulation with ferric chloride on existing processes at the 285 MGD Potomac Water Filtration Plant (WFP) and to develop biddable design documents for new ferric chloride and sodium hydroxide chemical storage and feed facilities at that facility. Project Outcomes and Benefits Identied the impacts of ferric chloride use on residuals handling and disposal, distribution system corrosion potential, and materials compatibility, among other issues. Design new coagulant feed system to work with either ferric chloride or ferric sulfate. Innovative use of the plant’s existing lime feed silos to house sod
