Height-Diameter Ratio

Post by gwlmr6 » Wed Mar 19, 2008 8:46 pm


I posted this a week or so ago, but it seems the post has disappeared. My question was how the height-diameter ratio is determined for UASB or EGSB type digesters. I can't seem to find this information anywhere. I have been told that the height needs to be much larger than the diameter to prevent biomass washout.

I am currently working on a project building a small scale, laboratory anaerobic digester and I am trying to decide the dimensions of the digester itself. I would greatly appreciate ANY advice.
