You measured and cut the feeding tube so precisely and then just cut a random length off the other side lol 😅

Do you have to use a pump to circulate biogas?

You need a flexible trowel for your burnishing! It will make corners a breeze…

Hey man, looks really cool. Is there anything you'd do differently down the line now? Want to make one 👍

Hi! I am a college student from the Philippines and is wondering how can I formally contact you? I have a few questions regarding water scrubbing and hope to have a discussion with you 😊

Should use all plastic parts the methane will degrade metal

looks great. Only thing I would do is put it in a ventilated box outside.

Thanks a lot❤ Needed it for a project of mine

Can anyone clarify me four pips installed on the top first for inlet 2nd is gas outlets third is for mixing and what for the fourth which is very thin and installed on the side

I have also made same model in 200 litter drum all is fine but when surly came out from outlet h need air "from where come that air" so that gas Which stores in tube, that gas goes back to drum, do you have any solution for this problem

Suggetion what if you made a magnetic sterrer at the bottom so that its easy to stir inside

How long before the water is saturated with CO2 and needs replacing? Also; the solubility of the CO2 is higher the lower the water temperature. ie: running water to the bubbler with a float valve and using evaporative cooling like wicks to both slowly empty it and cool it may be an idea. Good wicks are carbon felt as found in oven filters, welding screens, etc and in the activated carbon filter that should in fact be the last stage in your filtration system..! Or you could simply use a piezoelectric pond mister. Evaporation cools both the water and the air the water evaporates into, so the cooled air could be used indirectly (smell) for efficient home cooling... You certainly DO NOT want the (same old water) water bubbler inside the hot greenhouse and/or in the sun..! As it's moist iron oxide that reacts with/filters out sulphur dioxide do not put a drier before the steel wool. You want it to rust. www.sciencedirect.com/topics/engineering/iron-sponge-process Water vapour disassociates into hydrogen and oxygen at flame temperatures where it immediately burns to water again but it suppresses soot production in the process. www.sciencedirect.com/science/article/abs/pii/S0360319921025581 So the wisdom of removing water vapour at all, is in question..?

Great video

How often do you need to change the filter mediums?

I love the trial and error parts included. It lets people know that they are going to run into challenges. So many time I have found myself in the same situation. "Okay how do I make this happen" then you just climbed up on top and made it happen lol. Love it. Very nicely done! new subscriber gained.

Nice. Just one suggestion from a point of safety regarding gas. Only takes a few minutes tops. No matter how many clamps or fittings or plumbers tape are used. Once set-up is complete put the system from start to end under pressure. Use good old fashioned soapy water. Check ALL connections for possible gas leaks.

Thanks for this informative tutorial, I would like to know more about second jar, what did you use . I see white powder, it's of which material or component?

You could just use rabbit poo too I think

How often should each filter need to be changed? Or is there a way to test it?

Please what are the contents of the 3 scrubber. I know one is water, what about the other 2. Thank you

How are your systems doing??

Put a bit of pickling lime in the water to precipitate the CO2.

Does the order in which the purification done matter?

hi, can an alkaline solution instead of distilled water when removing CO2 in the purification of methane.

I want to see this operate an instant water heater

How do you replennish the CO2 reaction in water? Maximum von entrationbwill be reached and then? Baking Soda? Calcium containing chalk-Rock? Regular change of water?thanks

Good day. Thank you for the video. I built a similar digester here in Namibia but I have a challenge of gas leaking out between the universal seals and the pipe. Do you have any sealant to suggest?

Thanks for this. Really clever using cat litter. Hadn‘t thought of that. For heating, would maybe encasing your digester in compost be a reasonable heat source for avoiding decommissioning in winter?It would require a high heat compost with enough nitrogen and cellulose, but seems like a good off-grid thing worth experimenting with.

When using that type of hole saw, it is possible to enlarge the hole by fitting the original size hole saw, inside the larger hole saw. This will help, centre the larger hole saw, and stop it sliding about.

Might be better to put the steel wool after the water and the dessication medium (cat litter) last. Two reasons. -The hydrogen sulphide reacts with iron oxide, water is needed to rust the steel wool to make the iron oxide available. - reaction of iron oxide and hydrogen sulphide produces iron sulphide and water, but your dessication medium is before the steel wool, so there is nothing to remove this water.

Suis très curie de savoir comment fabriquer le biogas dans le fut plastique de 200lts merci mes conduire pour avoir cette nouveau technologie

The h2s scrubs better with humidity so you should go through the water then the wool then kitty litter

Those top pipe not airtight will d gas not leak out or have air ingress?

I didn't get d name of d gas drier you mentioned

You should remove the H2S first because it scrubs better with humidity

Thanks for nice explaination brother

Any luck with the gas? What are you doing with your scrubbed gas in the bag? Are you going to use it to generate electricity or something else? Did you build a water heater to get the temperature up in the digester? I have a lot of grass and am wondering If I'd be able to produce bio gas from it. Hope you've not given up?

I guess you don't get pressure enough, might need an air pump to push it through.

I enjoyed the video. What thickness is the gas holder ?

Good job but how can I learn about it from the starting to the end

RUclips is a 1st amendment sucking platform but they are good for some content,thnx for the video brother

So I just built a chicken shack by watching RUclips videos.and now I'm building a Cobb oven by watching RUclips videos lol

would this get rid of odor in biogas

..yes yess stop..how long..how deep become the pipe's !??

Thank you for making the video. The explanation was detailed and very helpful. The function of stirrer is interesting. It was helpful to make a biogas system for my house.

Any news on this build? Looks amazing, would love some stats on production.

Exactly what I was looking for🎉

I promise you that you aren't pulling the CO2 out with that bottle of water. Biogas is roughly 1/3 CO2 and you can't remove it with water.

You should add an activated carbon filter after the steel wool. My understanding is that it removes VOCs. Cleaner burn and you don't have to store them in your gas bag.
