Cleaning biogas collection systems

I know this is bit odd and i just dont get it. I do get that you get a liquid which can be harvested from biogas but do you ever need to clean out solid mass? for example sediment accumulates? if that does happen does that mean you did it wrong. Sorry about asking it is probably in a 101 somewhere i wasnt able to find. I did a search on cleaning out but wasnt able to see anyone say anything about it.

I have read a lot about biogas lately and no one mentions this.. so you are right in asking. I can't imagine it accumulates any faster than the sludge at the bottom of a septic tank, though. Depending on the size, you might expect to pump it out once every few years, or so. Probably easy enough to call a septic company to do it. But I too would like to hear reports from actually experienced biogas folks. Sadly, very few seem to exist in the US or any other northern hemisphere western countries. I have yet to find any decent interactive resources on the production of what I would call appropriately sized biogas plants, by which I mean ones that are larger than the 55 gallon drum variety (basically useless time wasting) and the massive municipal sewage treatment or industrial dairy or pig farm scale (much too large). Why is it that no one seems to see the value in harvesting methane? Anyone with a little acreage should find it just as convenient as a composting toilet, but with much larger returns! I am trying to get up the courage to just dig up my old septic and try and convert it myself, but it would improve my confidence immensely to know that others have done it and succeeded.

Can you tell me a little more about the systems you are using to get the biogas and the liquids?
I have run what might be called biogas systems at an industrial scale but I am not sure we are talking about the same thing.

I haven't picked one yet i was wondering if they did need to be empty out from time to time? how it is done and what to do with the waste if it is empty

I keep reading bits and pieces and watching movies about it but i hear no one talking about the fermenter slurry? i think it's called. what happens to it. do you empty it out and feed it to worms to bring down smell is there a smell.. should system be design with the empty out in mind . once bigger then a certain size. also.. i saw things like storage bags
