Thanks for this great explanation, allow me ask two things 1. Does the overflow pipe have to reach right at the bottom of the tank? 2. What is the height of the hole on the overflow from the bottom of the tank? Regards

Yes❤

Please do not use alcohol as a lubricant for rubber seals.

If you work with something that turns, don’t use any gloves, because it is very dangerous. It’s ravels up on the turning item with your hands inside!

Thanks for your explanation. How much methane gas do you produce with that size BD container? In cooking time would it be about one hour a day? Thanks again! Antonio from Argentina

The best educational demonstration on constructing a biodigester I've found! This is fabulous! Thank you for your time and effort!

Thank you - great explanation! And I like the wool standing in for the poop.

..hi lady..great video..This is the best video i've see..now its clear how the system to build..Thank you soo much !!

Good explanation 👏 😊😊

I love the cut-away.💜

Great tips

Me hubiera gustado que mis oídos y el fascículo arqueado del cerebro, situada en el lóbulo frontal, en el hemisferio izquierdo, pudieran decodificar su forma de expresión oral, el Inglés, no lo parlo ni lo comprendo mucho, pero es usted una mujer con una gran sensibilidad para transmitir conocimiento por su simpleza y sencillez y un paso a paso metódico, hacen del proceso enseñanza aprendizaje sencillo que no necesito saber Inglés para aprender con usted, muchos han realizado este video pero no transfieren ni trasmiten el conocimiento técnico/práctico en el montaje del prototipo, gracias, cudes, un abrazo. La miro desde Riohacha, La Guajira, Colombia.

Thank u very much for the illustrations and am going to build one ,

Nice

Doesn’t sand the barbs off the hole,uses rubbing alcohol on rubber seals,that degrades the seals,this is not the way to fit seals

❤

Thank you sooo much for simple well detailed description tutorial ❤🎉❤

It’s in Delaware , New Jersey and Maryland

Bro we are getting smoke halfway down the east coast. The fuck am I supposed to do about it?

i think we should cancel fire because of its horrible pollution and climate change.

Hello from Wisconsin. The smoke from those wildfires up there has been hazing out the sunshine for the better part of a week down here. With fires already starting in California and Nevada it's not going to get much better any time soon.

Love you you light for poor people

I succes to realise this experience.

Thank you for this excellent video. However, I need some help. I tried repeating it but was not able to activate the digester. Its been more than 40 days. Please advise.....How do i troubleshoot??

Best demo class..and beautiful explanation..namaste 🙏 Sister

Excellent explanation! Thank You.

Thankyou madam, i will try this model for my house

Wow perfect explaination

You must be a teacher. Good work

very articulate great work madam kathy

Well presented thank you, but very hard to hear

Cutting holes in reverse works better thanks. Alcohol is a solvent may react badly? Silicone lubricant is not reactive with rubber/plastic

Keep up the good work and best wishes for the future. Keep up the good work

Keep up the good work and best wishes for the future. Keep up the good work

Keep up the good work and best wishes for the future. Keep up the good work

Keep up the good work and best wishes for the future. Keep up the good work

This is the best explanation I have ever seen on the urine channel.thanks

God bless you Mama, I love that. I want to ask you one more question, can that one drum of digester supply a house whole

Why didnt you film a night sence of final result?

Muy interesante,

Great video

Assuming that gas line was coming out of the Puxin scrubber it may be sulfur as well as iron oxide. Iron oxide is desirable in the scrubber system because the Hydrogen Sulphide that you are trying to remove reacts with that and not the raw iron. The reaction is H2S + FeO2 -> FeS + H20 So the Hydrogen Sulphide reacts with the rust on the iron balls and produces iron sulphide and water. The water generates more iron oxide (rust) creating more reactive surface area for the Hydrogen sulphide. This is also an endothermic reaction and works most effectively above 20ºC However, iron Sulphide reacts with oxygen and turns back to iron Oxide + sulfur (FeS +1/2O2 -> FeO + S) So you get rust and sulfur produced which is probably what you can see in the tube. So the appearance of rust is not an issue and supports the scrubbers chemistry. What you may find is that the rust inside the Puxin scrubber has bonded the balls together and reduced its overall surface area. you might be able to alleviate this issue by smashing the container on the floor a few times to break apart all the rusted together balls. Also because the iron sulphide reaction is exothermic a large scrubber that has not been purged for a while could spontaneously ignite or at least get very hot when opened to the air. It's possible that enough oxygen is coming from the biogas to prevent saturation of the scrubber with iron sulphide. Because the steel wool in the new scrubber has a much greater surface area its possible that all of the steel wool structure will corrode to iron oxide powder and bond together into a solid lump in the new scrubber making it less effective over time. I guess thats why the Puxin uses steel balls to mitigate the iron oxide gluing everything together. Ideally you want to get a gas analyser that can detect low levels of Hydrogen sulphide and measure the raw gas and scrubbed gas to see how effective the scrubbers really are. www.sciencedirect.com/topics/engineering/iron-sponge-process#:~:text=H2S%20reacts%20with,form%20iron%20sulfide%20and%20water.

Hi! A very good tuition on Diy biogas. Simple question why do we put gravel down first in the burell?

Thanks

looks good. is there a noticeable difference? does the gas look and smell different with this on? Is rust the biggest concern with dirty biogas?
