Description
The challenge of full-scale implementation is to duplicate or exceed results obtained at the demonstration scale. In addition to upscaling process selection, obstacles are materials and equipment selection and application, site and structural configuration and optimization, regulatory uncertainty, and budget constraints and scheduling. A successful case study, the Randall-Bold Water Treatment Plant in Concord, California, is used to address these issues. The plant was constructed jointly by the Contra Costa Water District and the Oakley Water District. Terms of the CCWD-OWD agreement are given. A detailed discussion of the upscaling process is given, involving grit removal, pre-ozonation, flash mix, flocculation, filtration, final disinfection, and start-stop operation. A variety of features were incorporated into the plant design to accommodate conditions requiring a special approach, or as capital and O&M cost saving features. One of the most cost-effective techniques was a consistent design for similar elements of the plant. Details are given on plant features, including consistent design, ozonation, pumped diffusion flash mix, hydraulic flocculation, deep-bed GAC-Sand filters, distributed control system- SCADA, and toxics containment and control.
