Sewage Plant Chooses New Biofiltration System
The Binghamton-Johnson City Joint Sewage Treatment Plant (B-JC JSTP) in Vestal, NY, has awarded a $9.7 million contract to Ondeo Degremont for a three-stage biofiltration system integral to the expansion of its wastewater treatment facilities. Binghamton-Johnson City is required to meet strict effluent limits for discharge to the Susquehanna River, a Chesapeake Bay tributary. The plant upgrade will increase secondary treatment capacity during peak storm weather flows.
Ondeo Degremont will supply a three-stage arrangement of its BioforRegistered biological filters for carbon removal, nitrification and denitrification. The first two stages will treat a maximum monthly flow of 44 mgd and a peak flow of 70 mgd. The third stage will treat a peak flow of 49.5 mgd. The filters will fit within the existing plant site, with maximum use of existing basins.
A five-month pilot study at B-JC JSTP confirmed design criteria and operational requirements. In addition to system design, process equipment supply and installation, Ondeo Degremont will provide startup, commissioning, performance testing, installation supervision, and operational support. Construction completion for the first two stages of the BioforRegistered system is expected in 2003. Construction of the third stage is scheduled for completion in 2004.
Binghamton-Johnson City and C&S Engineers of Syracuse, NY, chose a biological filtration system rather than a conventional activated sludge system, which would have required a significant increase in Binghamton's plant area.
City Contracts for New Customer Management System
SCT has signed a contract with the City of Kansas City, MO, for an SCT BannerRegistered Customer Management System (CMS). The contract, which includes software and related services, totals approximately $3 million.
Kansas City Water Services Department chose SCT solutions to improve customer service and provide new products and services and advanced reporting for the municipal utility's 175,000 wastewater, storm water, and water customers.
Banner's CMS system offers the city enhanced billing services by enabling consumers to access account information online. This Web-based application also provides account details and other requested services, while helping the utility deliver efficient customer service and focus on the growing needs of its customers.
Colorado City to Install New Wastewater Treatment System
Kaldnes North America has been chosen to supply the city of Broomfield, CO, with the company's Moving Bed Biofilm Reactor (MBBR) process to treat municipal wastewater. Under terms of the contract, Kaldnes will retrofit Broomfield's existing aerobic basins with the Kaldnes media, an aeration grid system and sieve assemblies. In addition, there will be new construction for phosphorus and nitrate removal.
The MBBR uses millions of tiny, polyethylene biofilm elements to provide a home for an active bacteria culture. These buoyant elements are kept in constant motion throughout the entire volume of the reactor, resulting in uniform treatment.
Kaldnes process can be used to upgrade an existing BOD plant into a total nitrification system or increase the treatment capacity of an existing nitrification plant to meet new higher projected flows and strict regulations.
