What is the process envelope, and how do I read it?
sourced
It is the safe operating window for the digester, read from three numbers: HRT, OLR and blended C:N. The panel flags attention when HRT falls below 18 days, OLR rises above 4 kg VS per cubic metre per day, or C:N leaves the 20-35 band, and it fails at OLR above 5. Those thresholds exist because acidification from overloading is the failure that costs weeks of output.
