Abstract:

The demand for reclaimed water in California is ever increasing as population grows and new water supplies become scarce. As a leader in the industry, Central Contra Costa Sanitary District (CCCSD) has operated a tertiary treatment facility capable of providing reclaimed water for unrestricted use for many years. While the treatment plant has adequate capacity to process future flows, the disinfection system is restricted due to the inability to provide adequate contact time. Computational Fluid Dynamic (CFD) analysis was utilized to analyze the contact time of the existing reservoir. Once the flow through the existing system was determined, baffles were strategically located to improve the contact time within the basin to meet future flows. The CFD analysis enabled the District to increase the capacity of the reservoir from 2.45 MGD to 20 MGD.
