You''re talking w/somebody versed here- me.
You cannot run aerobic and anerobic at the same time in the same vessel. Just the two definitions bear this out.
I began working on anerobic digestion in 1973 during the first energy crisis. It didn't make economic sense then when the barrel price of oil was $80US in today's terms.
Second, the ROI is something in the time frame of decades, not months or years because of the capital costs and the amount of revenue generated from electric sales. Don't forget, any prudent businessman will buy electricity if it's cheaper to buy than to pruduce himself. The government won't give tax credits and grants indefinitely. And you can't get a sane financial institution to put up the money since the life expectancy of the equipment is way less than the time for ROI.
Third, Ice is right in his post about the sulphur. The maintainance on that stuff is tremendous. The sulphur hardens valves, springs, bascially ruins everything it comes in contact with.
Finally, try answering the question I already put forward. How does IBR generate a stable end product in 25% of the time it takes for the normal process to occur.
If the anerobic process takes 30 days and the arobic process takes seven, AND YOU CAN'T DO BOTH PROCESSES AT THE SAME TIME IN THE SAME VESSEL, HOW DO YOU GET A STABLE END PRODUCT IN SEVEN DAYS????????
Now, are you going to answer that one or shall I?
I think you already know what I'm going to say.
