Westchester Joint Water Works to build Zenon
water treatment plant

ZeeWeed to filter New York City source water for adjacent county

OAKVILLE , Ontario , July 18, 2005 – Zenon Environmental received a purchase order for its first drinking water treatment plant in New York State. This plant uses both of the company’s main products, which together will deliver a total of 20 million gallons, or 94,635 cubic meters, of drinking water per day using two separate Zenon systems.

One system, the larger of the two, will incorporate the ZeeWeed 500 series of membranes while the other will use Zenon's 1000 series of membranes. Both are hallmarks of the company’s hollow-fiber immersed technologies.

John G. Hock, P.E., Manager of the Westchester Joint Water Works, stated, “Together with our consulting engineers, Hazen and Sawyer PC, we determined that the Zenon membrane vacuum type filter system was best suited to treat the water from Rye Lake. This decision was made after first reviewing traditional filtration systems and then evaluating different membrane systems.”

Rye Lake is an offshoot of the Kensico Reservoir, which also supplies New York City residents with drinking water.

The design phase is virtually complete with construction expected to begin in the fall of 2005. The plant will be finished by the end of 2007.

ZENON is a world leader in providing advanced membrane products and services for water purification, wastewater treatment and water reuse to municipalities and industries worldwide.
