Emerson completes WDPF-to-Ovation Control System Migration at water plant
The facility treats secondary effluent conveyed via the Districts Hyperion Secondary Effluent Pump Station located at the Hyperion Wastewater Treatment Facility. Through advanced purification technologies including microfiltration, reverse osmosis, and UV light and peroxide treatment ECLWRF makes five different qualities of designer water the only treatment facility in the country to do so, according to the district. Use of this water ranges from irrigation to ultra-pure water for high-and low-pressure boiler feeders and cooling towers, as well as recycled water that supplies the areas seawater intrusion barrier. Providing more than 30 million gallons of recycled water throughout the South Bay every day, West Basin replaces enough drinking water to supply 60,000 households annually.
The project, in which Emersons previous-generation control technology was migrated to the state-of-the-art Ovation expert control system, supports a plant expansion the fifth expansion since the facility was built in 1994 that is necessary to meet the needs of the region. Emerson worked with West Basin, as well as its on-site construction management contractor to successfully complete the project.
Emersons Ovation expert control system now monitors and controls microfiltration processes at the ECLWRF as well as three satellite facilities:
For this comprehensive migration project, Emerson supplied a total of 17 Ovation controllers and 19 workstations. Separate Ovation highways at each site are networked together, enabling operators to monitor and control processes at the satellite facilities from a central location the ECLWRF resulting in enhanced efficiency. In all, the Ovation systems manage nearly 20,000 I/O points. The project was executed in phases, ensuring that there was no disruption in plant operation and service to the districts municipal, commercial and industrial customers.
Emersons Ovation system allows a straightforward migration path for users of its previous- generation WDPF system. This proven, economical alternative to complete system replacement offers WDPF customers the latest technology while allowing them to retain much of their existing control system investment, including control logic, graphics, I/O cards, field cabling and terminations.
We were looking for a robust control solution that could accommodate not only a plant of this capacity, but also the complexity of producing five customized water types, said Don Zylstra, senior water resources engineer, West Basin Municipal Water District. Not only has the new Ovation system greatly increased the number of available I/O points, it has also improved the communication and visibility of plant processes taking place at satellite facilities, continued Zylstra, adding that West Basins ability to keep some of its existing investment in Emersons previous-generation control technology was another major factor in the Districts decision.
West Basin joins such other major metropolitan areas as Chicago, Detroit, San Diego and Washington, D.C., to name just a few that rely on Emersons automation and control solutions to help them ensure cleaner, safer water supplies, reduce environmental hazards and improve operational efficiency.
We are pleased to continue our long relationship with West Basin Municipal Water District, and are particularly gratified to be associated with what is one of the countrys largest water recycling facilities, said Bob Yeager, president of the Power & Water Solutions division of Emerson. Migration to our Ovation technology offers the District the best of both worlds a solution that is economical, yet also ensures that they are able to accommodate their evolving needs well into the future.
