Appeal No. 95-4025
Application 07/996,968
appellants’ claims 1 and 4-6 as amended after final rejection.
These are the only claims remaining in the application.
THE INVENTION
Appellants’ claimed invention is directed toward a method
for simultaneously aerating and agitating sludge wherein air
bubbles having an average size of about 0.25 mm are dispersed
into the sludge as the sludge is agitated. Claim 1 is
illustrative and reads as follows:
1. A method of simultaneous aeration and agitation of
sludge, said method comprising;
moving atmospheric pressure air through a confined
elongated zone into a larger zone of reduced air pressure
which contains sludge;
dispersing extremely small reduced pressure microbubbles
of an average size of about 0.25mm into the sludge while
simultaneously agitating said sludge; and
maintaining the dispersed microbubbles in said sludge to
increase lateral oxygen transfer to replace oxygen used by
aerobic bacteria.
