In 2005, Seacoast Utility Authority (SUA), located in Palm Beach County, Florida, evaluated options for expanding their two existing water treatment plants to meet future demands, and for converting their plants from lime softening facilities to membrane softening facilities. SUA commissioned a preliminary design evaluation to study various options for expanding their existing water treatment plants to meet future demands and for converting the plants from lime softening facilities to membrane softening facilities. This report included a description of the process and components required for each option evaluated, a proposed schedule to implement the improvements, design considerations for the improvements, as well as the estimated capital and operation and maintenance costs for each option. These options were based on existing facilities, water demands and plant capacities, water quality, water treatment regulations, concentrate disposal options, and permitting requirements.
