Thank you for cutting up an IBC to show the world

[@SolarCITIES]

Our pleasure! I love arts and crafts! ~ Janice

Great video and a well thought out design, just a couple of tweeks to the gas store I'd consider, some form of rail to keep the top straight and stop it from tilting over and leaking gas. Also some weights to the top of the lid to increase pressure at the gas pipe, Meaning you can pipe it further away with better flame pressure. Well done and would be great to see an update.....

[@nicholasdworcowyi5735]

Thank you for a simple visual explanation, easy to understand.

[@SolarCITIES]

You are very welcome. That was our intent.

El mejor video que he visto sobre biogas.

Gracias Señor. Muy apreciado.

Amazing 👏

Thank you!

Well done

[@hispanicuscorpus]

thank you

[@DavidJohnson-dc8lu]

Best Biogas video yet, and the gas looks like it was stored much safer than an inner tube or some plastic bag. However, why was the gas tank filled with water? Do you need an outlet for overflow?

[@SolarCITIES]

Thank you David. An IBC tank does not "deflate" like a bag or an inner tube. It works as a floating gasometer. Each rail is about 200 liters of gas. You can see how much gas you are producing by how high it rises. When gas is used it lowers, when it produces gas, it rises.

[@jackmclane1826]

Does agitation help in gas production?

[@Galv140577]

How much can it be scaled down?

[@Kolo_musicc]

Can we have more infos ? maybe video ? on floating system for gaz storage this video is amazing thank you

[@iamthedude642]

Awesome!

[@mbalireallen9115]

Sorry simple

[@SolarCITIES]

@@mbalireallen9115 Not simple for everyone, but we want to make it so.

[@bradlyjohnson60]

Pardon my ignorance how much food waste to manure? And how much food waste too gas do you get per daily use? How much do you have too feed this thing is what im asking.

[@felipecenteno9755]

( 2:45 ) is it recommended to have that sponge in the bottom? or that was only to represent manure?

[@spa1st]

only for representation

[@vjaycuarteros2051]

Can you share the dimension the pipe and material to be use. Thank you

Where is water level?

[@ahmedqailani4734]

Hello dear , can I get data about the size of tank and the quantity of product gas , don't forget to mention the type of material that use . Thank you .

[@SolarCITIES]

This tank is 1,000 liters. Please look at some of our other videos to see what we use. You will use whatever works in your region of the world. Find us on Facebook at "Solar CITIES Biogas Innoventors and Practitioners" and join the conversation!

[@Hermit_of_the_Holler]

What keeps the pressure from pushing the 'digestate' up and out of the feeder tube..?? Thank you

[@saulthompson6613]

Outlet pipe exit is sitting lower therefore it takes less pressure to exit that way. Inlet pipe is higher, it takes more pressure to exit there. Higher pressure will never be achieved since it will be relieved through the exit pipe.

[@Hermit_of_the_Holler]

@@saulthompson6613 thank you

[@justoneman1318]

If the methane isn't used for an extended period is there a safety valve that prevents gas pressure from building? What are the safety concerns associated with biodigesters?

[@NinoJoel]

The Gasometers will reach a point where the top half will be so high that the Gas escapes trou the water into the air

[@stephenmateer9868]

does the water in the methane storage devise harbor insects? mosquitos?

[@NinoJoel]

Should not since they don't have any place to get to the water

[@Sawyer0ne]

Please, I have a few question, if you can answer it would be a big help for me. What about static electric? No worry that can be dangerous? How you seal the pipes to the IBC? If with glue, doesnt it will corrode via UV? In my country in winter, the temperature between -5°C and +5°C. Is it a problem? May the process stop in cold temperature, and start when 22°C again, or it is going to ruin, and i will need to make a new slurry every vear? And my thought was isn't easier to put a barometer on it than put in floating? Thank you!

[@NinoJoel]

The floating part is important for safety and pressure. If there is to much gas ir will escape without damaging anything. If you use the gas it regulates the pressure and makes the gas usable. The temperature inside the tank should always be around 25 or more or it will not work. If it freezes it damages the tank

[@NinoJoel]

Also static electricity is not a problem with IBC tanks since the material does not charge up easily. Even if it does the gasometer will just flip the top half

[@user-nw4ot9ve8e]

It is not LIKE a animal digesting system as it does not have acidic digesting. It is just an anaerobic fermentation.

[@minorarce]

Hello, I have a question. My biodiogester is full of water and each time I use the water out, that's normal??? What can I do???

[@saulthompson6613]

Use that water to feed nutrients to your garden. You put stuff in, stuff must come out.

[@alennnnn]

But the gas will escape from the slurry pipe. Say when your waste is not yet up to the half way point where the slurry hole is. Then the gas will escape right?

[@lizhu5570]

H ali! The first thing we need to do is filled the whole tank with manure and water, so that it will remain the whole anaerobic atmosphere. In this case, the gas won't escape from the slurry pipe.

[@alennnnn]

@@lizhu5570 ok that answers my question. Thank you sir!

[@lizhu5570]

@@alennnnn Anytime!

[@SolarCITIES]

While answering questions, the response to this one was mistakenly deleted! We don't fill the entire tank with waste. Only 1/40th of it to start and every feeding after it begins producing gas. We actually fill most of the tank with water all the way to the top, but not above the outlet pipe or it will pour over.

[@charlesmasey6815]

what part of solids and what part water is needed?

[@lizhu5570]

When we mixed with cow manure and water, usually the ratio of them is 50/50.

[@SolarCITIES]

1/40th of the size of the tank.

[@SolarCITIES]

@@lizhu5570 For feeding yes, but for the total volume of the tank it is 1/40th of the size of the tank.

[@garrygalvez9339]

Everytime you put food waste , equal volume of liquid fertiliser is forced out. Is this liquid ready to be used for the plants?

[@apinhmi]

Lee Nice video. Great work man. Question:. What is better, 1 big system like 10tonner bio digester or 10 smaller system of 1 tonner container? Appreciate you very well thought of response. Thank you! GBU! Farm produces 15 tonner chicken dung.

[@technologymentor786]

after few days when you need to empty bio digester it will be a dirty process. how to clean it please also demonstrate it.thanks

[@SolarCITIES]

We don't empty the biodigester. That's the point. Just like an animal, or even a human, it keeps digesting the food waste as long as you keep the methanogens alive and you don't overfeed it. This system has been alive for 6 years. If and when it needs to be emptied, the solids can be dried and sold as compost fertilizer. But that hasn't happened yet!

[@technologymentor786]

@@SolarCITIES impressive

[@alistairwylie6730]

@@SolarCITIES Thats a question I was going to ask, about the solids and how often it needed to be cleared out and how? With septic tanks for a dwelling sewage system, Its recommended every 5 years or so, but this depends on how you maintain the tank, by not putting down soaps, detergents and bleaches, basically anything that will kill the bacteria inside your septic tank. Which makes me think, could you use the gas from a household septic tank? These septic tanks have a vent, which I assume is to stop the build up of gases inside the tank. The septic tank that I have is being constantly aerated and has three linked compartments for the various stages of sewage treatment, the waste water, which is meant to come out clean goes to a soak away. Thanks for your video Alistair

[@JustinC905]

When emptying, does the liquid fertilizer smell? Is it considered fertilizer with anaerobic process is complete when it is emptied from the outlet? Can it be used straight away? Is there any way the tote can be opened up for the removal of fertilizer?
