There are six anaerobic digesters. Each is 100 ft wide with a maximum
operating depth of 35.5 ft. along the outer wall (volume in bottom cone is
normally ignored). Digester No. 6 operates as a "blend tank" receiving
sludge from the other 5 and mixing it before it is fed to dewatering centrifuges.
The plant is a secondary treatment plant nominally receiving an annual
average of 133 million gallons per day. The collection system serving the
plant has "combined sewers", which means that rainwater runoff is combined
with primarily domestic and commercial sewage. This makes the inflow to the
plant more dilute compared to areas with "separated sewers" where rainwater
is diverted elsewhere and the treatment plants receive only primarily
domestic and commercial sewage.
Here is some operating data. I'm sorry that the abbreviations will be a
little incomprehensible. I cannot find my files that are better annotated.
Have fun!

Sue, would you have any factoids at your fingertips that you could send this person?

To Whom It May Concern,
I am a member of a high school team in Daytona Beach, FL competing in an
Internet science research project. As our project we want to incorporate
your digesters into a wastewater management system.
Can you provide us with some numbers regarding the sizes of digesters and
the amount of sewage input/output? We would like to have ratios, if at all
possible, for the number of million gallons per day for the physical
dimensions for the following tanks:
Digester (pancake and egg)
Anaerobic tanks
Anoxic tanks
Filtration tanks
Also, what is there a ratio for volume of egg digester to methane produced
per million gallons per day?
This information will help us formulate the size of our facility. This
information is dire to our project, which is quickly coming to a close.
Thank you ever so much for your help.
-Randy J. Coslow
