Zenon reports three new bioreactor projects in U.S. states

Zenon has been selected to supply its membrane bioreactor (MBR) for what will be the largest system of its type in the world, to be located in Fulton County, Georgia. The MBR will treat 15 million gallons (mgd) of wastewater per day, providing high quality effluent for re-use applications.

Zenon's technology will be incorporated in the new John's Creek Environmental Campus near Atlanta, which will not only house a water re-use plant, it will be a major educational centre for water reclamation in the state. The company expects to receive the purchase order later this summer, with construction on the plant scheduled to begin in the fall. Plans call for the entire complex to be complete in 2007.

Building the new campus in an existing residential area presents several challenges, said Tim Equels, assistant director of the Public Works Department for Fulton County. "In addition to finding a proven and reliable technology, there are a number of other issues that we addressed, such as space, integration of the site into the community, noise and odour control. With Zenon's vast experience in membrane bioreactors, we were able to satisfy all these concerns," he said, adding that "we are also fortunate to have Georgia's first Zenon MBR plant, the Cauley Creek reclamation facility, running successfully in our own backyard."

Zenon has also received a letter of intent for an MBR-based wastewater treatment process at the Bonita Springs East water reclamation facility in Florida. The company expects to receive a purchase order shortly for this project, which is scheduled for completion by the end of 2006.

Demand for re-use quality water is gaining momentum in water-short Arizona as well. In order to respond to growing wastewater treatment needs resulting from increasing commercial/industrial growth, the community of Tempe, near Phoenix, decided to retrofit the existing conventional Kyrene reclamation facility and increase its capacity to nine mgd using the Zenon MBR.

Retrofitting of the existing facility with this unit will allow utilization of a considerable portion of the existing basin infrastructure. MBRs occupy a fraction of the space of a conventional wastewater treatment plant while treating at least a third more capacity. Once complete in the first quarter of 2006, this will become one of the largest operating MBR plants in the world.

"In addition to the orders above, we have also been selected and received letters of intent for our MBR system for projects in Washington State, California and New Mexico," said Zenon chairman and CEO Andrew Benedek. "This is clearly a signal that the technology has come more into the mainstream, particularly for water re-use applications."

The total treatment capacity represented by all of these projects is in excess of 40 mgd with a combined value of approximately $50 million.
