SOUTH SAN FRANCISCO, Calif., June 16, 2016 - The City of South San Francisco is proud to announce the installation of a new High-Efficiency Turbo Blower at the City of South San Francisco-San Bruno Water Quality Control Plant. The APG-Neuros NX350M-C070 Turbo Blower replaces a 250 HP centrifugal multi-stage blower for aeration need to the Treatment Plant's aeration basins. This was the 1,000th Turbo Blower installed in North America by APG-Neuros, a global leader in energy efficiency based in Montreal, Canada.
Water Quality Control Plant Superintendent Brian Schumacker says it was a significant process to get the new blower installed, but worth the effort. "Upgrading to the latest aeration system or blower technology is not as easy as upgrading to the latest iPhone, however doing so can help cut operating costs." Schumacker adds that aeration systems typically account for 45 to 75 percent of a plant's total energy consumption.
On average, the high-efficiency turbo blower consumes 165KW per hour of electricity compared to 230KW per hour for a conventional centrifugal multi-stage blower for the same demand. It is anticipated that the annual savings for switching to the high-efficiency turbo blower will be up to $100,000. The new blower also helps the environment by eliminating approximately 1,054 metric tons of CO2 greenhouse gas emissions annually, or the equivalent of removing 70 passenger vehicles from the roadways.
South San Francisco Mayor Mark Addiego, together with San Bruno Mayor Jim Ruane, and AGP-Neuros CEO and President Omar Hammoud, officiated over the ribbon cutting ceremony yesterday commemorating the new technology.
"On behalf of the South San Francisco City Council, we thank the Public Works Department for its forward thinking in looking for ways to continue to embrace cutting-edge technologies that support energy efficiency and sustainability. We look forward to our continued partnership with the City of San Bruno," said South San Francisco Mayor Mark Addiego.
There are many processes and technologies used to treat wastewater, but the main way is through aerobic bacteria. Aerobic bacteria are tiny, microscopic creatures. Millions of these bacteria colonies metabolize and break down waste. Since these bacteria require oxygen to live and grow, this is the defining factor for these tiny organisms.
"To keep these bacteria happy and thriving, the operation requires air...and lots of it!" added Schumacker, who noted that the new high-speed turbo blower technology allows the Treatment Plant to deliver air up to 75 percent more efficiently.
High-Speed Turbo Blower Helps Plant Operate Efficiently and Sustainably
A significant advantage of turbo blowers is the ability to maintain efficiency when wastewater flows are lower. For example, a plant may require 90 percent of the maximum rated flow of a blower system during peak flows and may only require 45 percent under normal operating conditions. Most turbo blowers have integrated variable frequency drives to scale down the blower and improve energy efficiency during low-flow times.
The Water Quality Control Plant has been in continuous operations since 1951, and currently provides service to over 95,000 residents of North San Mateo County. Among its areas of service are cities including South San Francisco, San Bruno, Daly City, and Colma.
