Batch weighing and dosing system hits pay dirt
A seawater desalination plant installs a batch weighing and dosing system in its pretreatment facility to improve water filtering capabilities.
Owned by Tampa Bay Water, the Tampa Bay Seawater Desalination Plant in Tampa, Fla., uses a single-pass seawater reverse osmosis (SWRO) system to remove salt and other minerals from seawater, producing more than 25 million gallons of clean, drinkable water every day for area residents. When the 30,000-square-foot desalination plant began operating in 1998, it struggled to achieve optimum operating efficiency because of various problems with the SWRO system’s design, including the pretreatment system responsible for preparing the seawater for desalination. To improve the plant’s operation, Tampa Bay Water temporarily closed the plant and formed a public-private partnership with American Water-Acciona Agua in 2004. The latter company was to remedy the desalination process and then operate and manage the plant.
