Parkson Corp.'s DynaLift MBR receives Calif. Title 22 approval

FORT LAUDERDALE, FL, Oct. 2, 2006 -- The California Department of Health Services has approved the use of Parkson Corporation's DynaLift™ Membrane Bioreactor (MBR) as an acceptable filtration technology that complies with the state's water recycling criteria (Title 22).

Parkson's innovative DynaLift MBR System provides a cost-effective and proven way to apply external tubular membranes to membrane bioreactors. The DynaLift MBR is a flexible, out-of-basin system that uses ultrafiltration tubular membranes with a simple biological wastewater treatment plant to provide extremely high-quality effluent for beneficial reuse.

According to Douglas Wachter, VP Business Development at Parkson, the approval of DynaLift by California is a milestone for the company. "This approval represents a tremendous opportunity for Parkson," says Wachter. "California's Title 22 certification is a benchmark for high-quality effluent throughout the country. We're looking forward to offering DynaLift's leading-edge technology to help municipalities and industry within and outside of California address their wastewater treatment needs."

The DynaLift MBR uses a simple airlift to sustain the cross-flow velocity and turbulence required to maintain membrane flux and permeability while significantly reducing the pumping energy required with traditional cross-flow systems. As a result, the benefits of an accessible, external tubular membrane system design may now be cost-effectively applied to membrane bioreactors. These benefits include proven long life of rugged tubular membranes, sustainable high flux and permeability, low operating costs, and greatly simplified membrane cleaning regimes and access.

Montgomery Watson Harza provided consulting engineering services in overseeing the test work required for state approval of the DynaLift System. The firm is headquartered in Broomfield, Colo.

Parkson Corp. (www.parkson.com), an Axel Johnson Inc. company, with headquarters in Florida and offices in Illinois, Michigan, Canada and Brazil, is a leading provider of advanced process and mechanical technology for applications in municipal water and wastewater, as well as industrial process water and wastewater.
