Mesa installation begins

12-19-06

OpenCEL, working with CH2M HILL’s Tempe office and Hunter Contracting of Gilbert, AZ, has started installation of a full-scale Focused Pulsed unit in the Mesa, AZ Northwest Water Reclamation Plant. Installation will be performed with minimal interference to ongoing operations and will be completed early in 2007.

 

Ohio Pilot Plant


A pilot operation in Lancaster, Ohio proved how easy it is to reduce biosolids. The volume of treated sludge dropped 80 percent with an OpenCEL unit in place. Battelle Memorial Institute gathered data and supervised the pilot project.

A trailer-mounted OpenCEL system was integrated into the sludge handling and aerobic biotreatment at the plant. The OpenCEL system treated waste-activated sludge at a nominal 7 gallons per minute feed rate.

Testing lasted 500 hours (three solids-retention cycles). The treated biowaste flowed back to the aeration tank bioreactor, where it was biodegraded.

After OpenCEL’s electric pulses bombarded the cells, the cells released soluble inorganic and organic matter. Tests show that treatment substantially reduced the fecal Coliform population.

The pilot project treated 39 tons (dry basis) of waste-activated sludge at a rate of 1.8 tons per day. Data showed an 80 percent reduction in sludge volume. That’s 31 tons of sludge that did not get trucked to the landfill.
