Results were pretty much steady-state, indicating that the seniors' research on running the anaerobic stage for an optimum time of 2 weeks was indeed correct; the concentration readings were relatively stable.
Sad Case, it rained heavily on both days... My laptop got caught in the rain and I had to send it for repair... This explains the late updates...
Due to the ongoing camp, we were forced to conduct our testing here instead of the usual area. At first sight, it seemed picturesque. On second thoughts, it was a horrible idea when we got caught in the rain, together with the equipment:
There we go, trying frantically to dry everything with a fan and tissue paper:
The Flow Regulator for the oxygen tank (to be connected to aerobic stage):
On Friday, we figured how to use the gas detector and subsequently drained off the human waste:
Did some labeling on the grey digestor for the future batches' easy understanding (all tags were laminated and water-proof):
As mentioned earlier, results were showing a near steady state trend. To further confirm that steady state has been reached, we will be running the anaerobic digestion process for an additional 1 week for research purposes. If the results show stability, 2 weeks would be taken as the future optimum anaerobic stage running time.
