Hello Grace<div><br></div><div>I am one of the normal observers here, having a small experience with biodigesters. I do have a bit more experience with apiculture but just thinking the nitrogen needs of a digester using honey. If you are working with large quantities of honey you probably have access to ruined pollen sources, which if used carefully would provide the nitrogen necessary of r a digester which is working mainly with your dilute sugar stream. <br>

Thanks folks for the quick response!<div><br></div><div>We plan to use the dilute clean streams for mead production (honey wine - alchohol)<div> </div><div>The contaminated (minimal dirt) streams will be sent to the digester.

<div>Dear Grace, </div>
<div>it is not so difficult or complicated. If you can estimate the sugar content in the honey solution, please see to it that the daily amount of sugar entering into the digester is not more than daily 1 g per liter of digester capacity. If however, you use the technology called anaerobic filter, you can safely intoduce 5g sugar per litre of digester capacity. Since you already have honey, add a cupful of milk once in a while to provide the nitrogen, and enjoy life in a land of milk and honey.</div>
<div>Yours</div>

<div>Is a dilute honey stream (from a honey processing plant) a suitable feedstock for a biodigester?</div></blockquote><br>Theoretically, yes, although: some source of N would need to be added; the digester would likely display a tendency toward low pH; and the stream should not be too dilute. Further, it is likely that a good deal of thought and effort would need to go into the feeding rate and the mechanics thereof.<br>
