EPA offers energy-management seminar for local water and wastewater plants
July 8, 2008
The EPA will be offering a free seminar on energy efficiency
to operators of water and wastewater plants in the Upper Midwest on July 22nd. Energy efficiency can be enhanced by a variety of means, including the use of high-efficiency motors and the recovery of biogas energy
from digesters. Efficiency, of course, is not just a line on a product spec sheet -- for instance, a solids-handling pump may have a lower nominal efficiency than a clean-water pump, but the clean-water pump would be totally inappropriate to a wastewater application. The amount of energy wasted on trying to return clogged pumps back to service is one of the reasons why Gorman-Rupp self-priming pumps
have significant advantages for many communities. By placing the pump above-ground where it can be easily and quickly unclogged, a Gorman-Rupp self-priming pump can turn out to be many times more efficient than a comparable submersible pump that has a higher nominal efficiency, but which requires far more time and effort to remove, unclog, and return to service -- not to mention the fuel wasted on excessive bypass pumping
. A total-system-efficiency view requires a broader look than just a line item on a specification.
