Deer Island Plant to get new human machine interface system
The Massachusetts Water Resources Authority (MWRA) will replace outdated human machine interface (HMI) systems at its Deer Island Wastewater Treatment Plant with Ovation technology from Emerson Process Management. The new interface will make it easier for operators to control daily operation and ensure regulatory compliance.
The plant, in operation since 1995, is the second largest in the United States. It serves 43 Boston-area communities and is the centerpiece of MWRA’s $3.8 billion program to protect Boston Harbor against pollution from the metro sewer systems.
When installed in March 2012, the Ovation solution will manage and integrate the plant’s legacy systems and numerous processes, including influent pumping, grit screening, primary clarification, oxygen-activated sludge secondary treatment, secondary treatment clarification, sludge digestion, sludge thickening, odor control, disinfection and effluent discharge. In all, it will manage 30,000 I/O points.
Treatment plants order turbocompressors
Siemens Energy has received several orders for turbocompressors for wastewater treatment in the U.S. and Mexico. The Southeast Wastewater Treatment Plant in Rolla, Mo., will install direct drive turbocompressors to provide compressed ambient air to meet biological oxygenation needs. Aguas Tratadas del Valle de Mexico S.A. de C.V. ordered 18 compressors for the PTAR Atotonilco treatment plant in Atotonilco de Tula in the province of Hidalgo. The Northwest Wastewater Technology Plant demonstration site in Springfield, Mo., will install a single STCDO turbocompressor. The City of Springfield will operate the plant.
DC Water breaks ground on Clean Rivers Project
The District of Columbia Water and Sewer Authority (DC Water) broke ground in October on a massive construction project to nearly eliminate combined sewer overflows. The groundbreaking ceremony and first construction projects in the series occur at the Blue Plains Advanced Wastewater Treatment Plant. The $2.6 billion Clean Rivers Project creates giant tunnels more than 100 feet underground that will store combined sewage during heavy rainstorms. The first tunnel will run along and under the Anacostia River.
Little Blue Valley district adds TrojanUV disinfection
Little Blue Valley Sewer District (LBVSD) in Independence, Mo., selected the TrojanUVSigna open-channel wastewater UV disinfection system from Trojan Technologies. The system is designed for large-scale wastewater disinfection. Trojan will supply three channels of UV banks with TrojanUV Solo Lamp technology. LBVSD treats wastewater from Kansas City and surrounding cities and counties at the 52 mgd Atherton Wastewater Treatment Plant.
Ithaca embarks on performance contract
The City of Ithaca, N.Y., and the towns of Ithaca and Dryden have selected Johnson Controls to implement an energy savings performance contract to maximize the energy efficiency at the Ithaca Area Wastewater Treatment Facility. The project is supported by more than $400,000 of American Recovery and Reinvestment Act (ARRA) funding. Upgrades began in September and will be complete in 16 to 18 months.
The project includes enhancements that will reduce energy and operational costs. They include modernizing the facility’s aging infrastructure, upgrading the cogeneration system, and replacing the digester cover, digester mixer and a boiler. Benefits are projected to include $9 million in energy and operational savings over 20 years, reduction of greenhouse gas emissions by 961 tons CO2 equivalent per year, creation of $15 million in economic development and spending, and creation of 80 jobs.
