Black & Veatch and United Water New York have completed engineering, procurement and construction for United Water New York's Lake DeForest water treatment plant upgrade.
The project has increased the facility's capacity from 10 mgd to 20 mgd, and incorporates AquaDAF® treatment technology, a high-rate dissolved air flotation process that uses air to float sediment and algae to the surface for removal to improve the quality of water provided to end users.
This is the first application of AquaDAF technology in the United States. The technology was supplied by Ondeo Degremont.
"Increased demand, coupled with more stringent regulatory requirements for total organic carbon reduction and the presence of episodic algal blooms stretched the existing Lake DeForest water treatment facility to its limits," said Janine Witko, Black & Veatch New York area manager. "In order to address increased demand, treatment compliance and water reliability and consistency, United Water New York selected Black & Veatch to upgrade the Lake DeForest facility to a 20 mgd capacity plant using innovative treatment technology."
In addition to the AquaDAF technology, the project included chemical feed system improvements, and associated electrical and instrumentation and control upgrades. As part of an integrated design-construction management delivery approach, Black & Veatch performed concept and detailed design, procured the major equipment and negotiated and managed the construction contracts.
