Stamford, CN - Clean Diesel Technologies, Inc. and Skanska recently announced the successful deployment of Clean Diesel's Purifier System based on its patented catalyzed wire mesh filter (CWMF) technology on Skanska cranes being used for the construction of a new water filtration facility in Croton, NY, a source of drinking water for Manhattan and the Bronx. The $1.3B project is the largest single construction contract in New York City history.
Clean Diesel CEO Bernhard Steiner says, "We are proud to be part of a project of such unprecedented scale – and pleased to provide an effective solution to Skanska. Our emissions reduction technology will enable Skanska to undertake this major construction effort with a dramatically reduced impact on the natural environment."
In a May 2007 press release, Skanska announced it had "landed its largest order in the US to date" ? a $1.3-B contract from the New York City Department of Environmental Protection (NYCDEP) for construction of a 377,000 sq.-ft. concrete water treatment facility and installation of machinery, piping and control equipment.
The NYCDEP requires all diesel-powered equipment which will be utilized on-site to use ultra-low sulfur fuel and to install Best Available Control Technology (BACT) to reduce particulate matter (PM) emissions.
Skanska is currently operating numerous cranes on-site which, because of the nature of the work, do not regularly produce a sufficiently high exhaust gas temperature to sustain the use of a passive diesel particulate filter (DPF). Conventional diesel particulate filter systems deliver inadequate total performance for this type of application and are high maintenance. Active–regeneration DPF's require the shut down of the crane engines to accomplish the regeneration. This presents a safety risk to personnel working under and in close proximity to suspended loads. Skanska, with the approval of the client, has successfully deployed the Clean Diesel Purifier CWMF System, since there is no need to shut down the cranes to accomplish the regeneration with this system. It has been verified by the U.S. Environmental Protection Agency (EPA) to reduce PM by up to 76%, nitrogen oxides (NOx) up to 9%, carbon monoxide up to 66% and hydrocarbons up to 89%.
Skanska Vice President Ali Catik says, "As a global leader in construction and development we take our responsibility to the environment seriously. This is why after discussions with the client; we elected to pursue the highest-rated EPA solution for this challenging low-temperature emission control application. Clean Diesel's technologies are world-class sustainability solutions that help us reduce the environmental impact of large-scale construction projects. When the Croton Water Filtration Plant is completed it will enable millions of New Yorkers to enjoy clean, purified drinking water."
"This emissions reduction implementation is groundbreaking within the industry, as it extends the proven performance of the Purifier CWMF System to construction crane applications", added Dr. Steiner.
