<br>
I have been wondering if it is really possible to blow up a
digester, has any one actually ever seen this happen?

There is very little info on the web about this subject except

You have to be more specific. There are a modest number of reports
from the 20s through, say, the 40s of catastrophic explosive
accidents involving municipal digesters. (See copies of the
venerable "Sewage Works Journal".) It is harder to find information
about explosive failures of low-tech and smaller digesters, but some
may argue that part of the reason there are so few reports is that
these incidents are bound to affect few people, in areas where
accidental death is not uncommon (i.e. it may not be newsworthy),
and where such incidents might be reported by those who installed
the digester(s), they have a vested interest in not so doing.... In
any case, it seems to be a fairly rare consequence.<br>
<br>
In response to the most general interpretation of the question,
then, yes: it is possible to blow up a digester.<br>
