Document Description
The Metropolitan Water District of Southern California (Metropolitan) proposes to replace the existing basin sludge pumps and install sludge density and blanket level meters to improve sludge removal and transfer to the thickening and dewatering processes; to replace the basin cleaning water supply lines to ensure efficient basin cleaning; to rehabilitate the original washwater reclamation plant, which has not been used since 1990, in order to make it suitable for temporary operation; and to convert Filter Building 2 washwater return pumps to variable frequency drive operation. These four projects address improvements required to reliably treat an increased percentage of State project water (SPW) at the Weymouth Plant than in the past. The increased use of SPW has resulted in the use of higher ferric chloride dosages to remove disinfection by-product precursors (e.g., total organic carbon and bromide). The use of higher ferric chloride dosages has resulted in increased sludge production.
