Reducing nitrogen production
Grontmij, who is the owner of the proprietary SHARON technology, is responsible for design, commissioning and process start-up. New York City has developed a Comprehensive Nitrogen Management Plan to reduce the aggregate effluent nitrogen loading from Water Pollution Control Plants (WPCPs) to the Upper East River and Jamaica Bay.
Separate centrate treatment has been identified as an integral part of this plan, since up to 40% of nitrogen loading at WPCPs with centralized dewatering facilities is directly attributable to centrate loading.
Highly efficient and cost effective
Pilot research by the New York City Department of Environmental Protection related to nitrogen removal and other related operational issues, showed SHARON to demonstrate significant potential as a highly efficient, cost effective and environmentally sound process for the removal of high levels of nitrogen from centrate.
New York City considers it prudent to evaluate this innovative, yet proven, technology at demonstration scale to determine its applicability as part of the long term nitrogen reduction plan for New York City and to verify the potential cost savings as a result of implementation of this process.
SHARON in New Yotk
Under the management plan, New York City is currently building a demonstration plant for the SHARON system at Wards Island WPCP. This SHARON will treat centrate produced at the plant in the sludge dewatering facility. This facility dewaters anaerobically digested sludge produced at Wards Island and at two other WPCPs.
The SHARON for Wards Island WPCP, with a capacity of 5.000 kg NH3-N per day, will be operational in 2009.
