I have been clearing the blockage every few days; when the water level in the inlet compartment rises about an inch above start-up levels. However, I noticed that the blockage was primarily at the entrance of the distribution pipe. There doesn’t appear to be any down the length of the pipe nor in the smaller ¼ inch holes that are spaced throughout the pipe. I also noticed that there is a lot of biomass in the inlet chamber. Since this is where I inject the organic carbon dose, I have decided this may be an issue. I have relocated the injection port directly into the bio-reactor, where I have the ability to stir and hopefully control the buildup better. If I can go a few weeks with no increase in restriction, this problem may have been solved. In any event, I guess the experiment will continue, even if I have to manually clear the pipe once a week.

I have adjusted the stir to once a day and the flush cycle to once a week.

The exact carbon dose is critical. Too little will eventually stall the system, which will stop cycling regularly. Too much and the system will cycle too fast and the ORP will drop out of control. I believe this is what the folks at DyMiCo have figured out as their system self adjusts and takes the guesswork out of my manual, trial and error method.

This system does lower the pH so I am using Kalk in order to try and maintain a higher pH.
