[Digestion] Biogas from sewage plants

[Montero Arguedas Jorge Mario]

I ve tried convincing our municipal plant engineers of this.  What could
be better than taking care of having the plants electricity bill taken
care of by the plant itself.

They say it impossible.  That the only viable feasible biogas production
way would be a UASB (or similar) to digest the sludge from the aerobic
treatment tanks.

Any comments,  further ideas on this ?

One wonders what the cost to enhance/upgrade our local sewerage
treatment
plants into bio-gas production facilities would be...it is worthy of a
national program..what about the distribution network for the gas....or
should electric production be integrated into sewerage treatment plants?


Surely some energy wonk 'out there' must be doing a paper on these costs
vies a vi the cost of corn to methanol, for example. ..... are sewerage
treatment plants an unexploited energy reserve?
