Excellent video & really informative. How much gas per day do you get? How much manure do you add daily? Thinking of doing something similar ourselves using manure and also veg waste... Any tips would be great ;-)
Question: Would not using tap water kill off some of the good bacteria since it has chlorine? Shouldn't distilled or reverse osmosis water be used (chemical free)?
Have you thought about using bacteria like rid-X or some other bacteria to increase the methane production and to decompose the maneur faster? I understand that water temerature is also a factor so if you are to increase the temp inside the digester you will have faster acting bacteria and gas production would increase, also your afluent (the liquid left over) will be clear and full of nutrients for your plants.
I really like this video it was very well thought out.would this have worked as a septic system and have just used the gas from that for heating and cooking?
right before your filter,you had a pressure regulator right? how many pounds of gas was it showing?i didnt catch the dimensions of your underground tank, I know you said 2 foot but 2 foot by what?or was that just the head space for the gas under there?I really like this video and am more into the design of this whole process
Could you use human waste for this? And also, this may be a stupid question but, do you smell anything inside the house (i.e., pony poop, rotten egg smell)?
@gabyrig I dont think you would want to use human manure or humanure because if you planned to use the slurry for garden purposes human feces carries to many bad pathogens,I could see this working for just about any farm animal though, pigs especially
@tappakeggaday1 I thought the same thing then I started looking around because I wanted to do that in a remote part of Haiti. I'm not sure what the UN does with the slurry because I couldn't figure out the rest of the Portuguese (I think) at the end of the video by the pond but it sounds like it's general practice.
@gabyrig now don't get me wrong, it could be used with human waste also, but I really think you would have to come up with more of a design based on a septic tank that breaks human waste down and have the head space for the methane gas to be extracted from. the over flow he has here is with the pony waste which like cow manure is suitable for growing plants in.
I love the info you have provided. Have you measured your production? For example, I shoveled 5 loads of poo and it produced me X number of pounds of gas.
Very interested in your production level. I would be great to produce this gas for a gas generator to power electricity for the home when service is down.
How is the gas contained? Is it just within that domed part that was tarred? Or are you compressing it into a tank for something, how about posting some full diagrams or your digester.
This is very clever. I'm going to think about putting something like that in at my house- I'm not convinced that it's a good idea yet, but I'm getting there! Thank you so much for showing your system in this much detail.
That dirty over-flow water you were referring to should be great plant food tea for your garden, instead of just dumping it. But having a lab tested just to be sure, would be interesting.
You should not allow the hose to sit in the mixing basin, the manure can back siphon into your clean water supply. Have any good ideas about using human waste from the house, or just carry the 20 liter bucket to the mixing basin. How big is your tanks?
I see you said it is 1.5 meters deep.
But at any rate thanks for building and using the digester.
Great video. Just don't understand why you don't clean the gas up before use. That would be removing the CO2 and H2S as well as the water from the gas thus purifying it. You would get a cleaner burn with no odors. And if you were making large amounts of the air you could compress it into a propane tanks. I have seen one recently that was the size of 4 bbq grill tanks stacked end on end but it was one single tank. Anyhow you should at least remove the H2S. It's corrosive.
@ParapaDrifter The best way to remove H2S is to run it through steel wool or alike material. CO2 and H2S can be removed by bubbling(fine mist) it through water in tube a 2-3 of times. You will have to change out the water (prdc). Now this adds water to Bio-Methane so that needs to be removed at the very last step. Water can be removed by condensation like you would on a still. Now there are chemical ways to remove these components. Just make sure you don’t add air to it. That’s explosive.
@Gruurk2 Does the steel wool have to be replace periodically? and wasn't he running it through water; would that not remove the CO2 if replace on a regular basis?
@Quefassa Yes, H2S is very corrosive so you do have to change it. Most replace it once per year during cleaning. If you determine that it has being used up (odor, PH) then you would change it then. No, that was why I made the statement about cleaning the gas. Overall he has a great design. Just that I would have performed what is called an upgrade (clean/purify) to the gas. It works ok the way he is doing it but if the rest was added then he would have a clearer burn and less dmg to the st
@Gruurk2 So what exactly do you mean by "bubbling(fine mist) it through water in tube a 2-3 of times." I took that as running the gas through water, as he did, but adding the step of changing the water periodically. What are you saying to do differently?
@Quefassa Try this, when you expose the biogas to water you want the maximum exposure to remove the H2S, CO2 and whatever else is in it. The larger the bubbles; the less overall surface exposure. The smaller the bubbles; more exposure. If you have a fish tank for example. And you want to add oxygen to keep the water oxygenated. You would use small foam like bubbles because this way it will react with the water thus increasing the oxygen. It’s all about surface area.
@Quefassa What soquelhigh did was he ran the biogas into a flash suppressor from the reactor. This stops a spark from going back to it and blowing up. Now, the Bio-methane comes out of the tank at 50 – 70% pure. You can perform an upgrade on the gas to increase the purity of it. So just using what we have talked about you could get the gas to 85 – 95% pure. It will burn much cleaner. Removing the H2S will keep the lines and the burners from corroding. Adding that one step; perfect.
@Gruurk2 Is there somewhere where I can see an example of this? And would this be an upgrade in the tank, and if not wouldn't the line between the tank and the filter always be in danger of corrosion? And if he were to pinch the end if the line submerged in the water, causing a more jet-like stream of gas blowing through the water, and change the water say daily, would that be enough to achieve what you are talking about or will it have to be something much more elaborate?
Cool I've been trying to figure out this design in my head and wonder how you added more material without losing the existing gas..thanks for this video...what do you guys actually use the gas for, and how much do you get out of it?
penetrate the manurer ball..that's what she said...
My great grandfather had a gas digester for his house many years ago, it had a safety valve on top that was always releasing extra gas so his neighbor asked if he could hook up to it too. They ran a pipe to his house, one day grandpa smells gas in the house, the neighbor had piled rocks on the valve to get more pressure, Great Grandpa cut the neighbors pipe.
For some of you who wants more information, please google "biogas unit for developing countries". There is a book of old research results dome by the Germans which is excelent starting point for manure digesting systems
is the maximum output of your system only enough to run one stove eye or is is more. I want to do something like this but havent figured out if its viable for my purposes. Id like to run a small heater...around 5ooo btu
I would probably use a different product to seal the inside of the dome. I used a cold tar product from Home Depot which smells like tar when I turn on the gas at the stove. :-(
This is a great video of an interesting home anaerobic digester. A really decent tour of the system's layout, operation, and product. Of course, I want to know more, especially what would be done differently if they could do it again.
