Biogas at Broward Dining Hall- Undergraduate Honors Thesis 2008

[ayansaim77]

hi sir we have just 1month internet i saw ur video i want o built this type of system can u send me ur system diagram how much intialy fill the tank and all caculation plz send my mail is tajamul77@yahoo.com i ho[pe u will send me

Hi, I would like to try tannery effluents for biogas is it possible- Thank you for this tube. Please let me know if it is possible - did someone try it

[henry01cora]

Hi, I'm from the Philippines and also trying to make use of my pigs manure. Is it possible to produce Biogas from them. kindly send your drawings to my e-mail address. henry_cora@yahoo.com. I appreciate very much as this will be the first Biogas digester in our place. Thank you very much for your help. God Bless You. Please e-mail me your thesis on this.

good job. i also want to make something like that can you help me by sending me some domentions please and thank you.

Hi. Very interesting project. Have a couple of questions:

1. When you started the project, did you remove oxygen from the digester

2. How much time does it take to generate the biogas for the first time?

3. Did you find any way to increase the production of biogas?

Appreciate your response. Any way we can get the paper you wrote?

Thanks

hi sir.. could you send me a copy of your paper.. I would like to have a proper measurement if things to fix.. do you have study about no.of hours to use the banked methane?

thanks

[ranjosim32]

I have one question, who's the dummy and who is the ventriloquist? LOL

I see the truck in the background moving its lips...hehe

[frojas777]

Great job!!... Do you have a Diamgram? if so could you tell me where can I find it.

Thank you Very much

I would like to start a project making Ethanol using Biogas to run the still. I figure Ethanol and Biogas could make a good team because you could feed the DDG to livestock and make a slurry out of animal wast. people worry about how much energy goes into ethanol. so i am looking for ways to make ethanol without using fossil fuel. I am a huge fan of ethanol.

[TruckinMike1965]

Great Job!. What a fun experiment! --- Have you calculated the required amount of gas to cook each plate of food and compared the waste per plate of food and its gas production? That would be an interesting and very useful piece of information. Also, take into account natural gas energy per volume vs that of the lower energy biogas (55% -70% CH4). Is the system sustainable? Inquiring minds want to know...

[studentgbrucker2]

I am working on making a larger digester for cow dung your project makes the project even more exciting as I will probabbly begin using school leftovers to help the digesters performance and help the school save on garbage great stuff

I am hoping to produce enough gas off my system to run a small generator off of twoo hundred cows

[mrgreendeeds]

This is a great, easy to understand video.I'm a sophomore studying Appropriate Technology and Sustainable Ag.I'm taking a BioFuels Technology course this semester and we are currently studying anaerobic digestion.Your project is a perfect example of sustainability.I'm interested in doing a similar experiment here, and possibly using the effluent at our school's organic farm.Can the effluent be added directly to the crops or does it need to be composted first?I look forward to reading your paper.

[ncbookz]

i do not understand the negative pressure deal how bout helping me out on that one anybody

[PersianPaladin]

Apparently, Sweden uses biogas for half of its vehicle fuel.

[grubyub]

cool! just like Mad Max haha

[IamGreed]

wow! good job. thanks for posting.

What was your overall biogas production at the end of your experiment?

Did you use any starter microbes in the system or just let it do it thing?

[BioEnergySustTechUF]

Hi,

Thanks for the comments. My overall biogas production was about 100L of biogas per 0.5 kg of food waste at about 70% methane.

Digesters typically are inoculated at start up. We generally use dairy manure as an inoculum.

[MrNavi1989]

@ naveen

hi you have shown a great venture

and i have a doubt regarding can we fill the biogas from collector drum into cylinders which use commercial purpose ? and biogas is how much same as ordinary gas ?

reply me..

[tanadar2]

hey Graunke2008 i google u and i get ur paper in PDF ,i like it tnx for posting it.

[BioEnergySustTechUF]

Great, let me know if you have any questions about my video or the paper.  How is your digester coming along?

[dmacosta1]

Keep up the good work

[tanadar2]

good job and nice expanation. im just constucting a contineus fed digester for my project if it is k with u ,would u email me a copy of ur thesis.10q 4 reading it.

[gkellett]

Nice work. Do you have a diagram of what the barrel looks like inside? IE do the pipes extend into the barrel any length?

Keep up the good work.

[BioEnergySustTechUF]

We're still working on a digital diagram of the digester. Basically the pipes only extend an inch or two into the digester so they can be inserted into the barrel but essentially they are on the side of the barrel.

[markallanfox]

Chalk me up as one interested in the finished thesis. Wouldn't mind an explanation of the digester itself either (although it looks straightforward).

[BioEnergySustTechUF]

Thanks for you interest. Basically the design is a barrel with an influent and effluent line and a stirring mechanism.  The liquid level is high enough to seal the main volume from air entering or methane leaving through the influent or effluent lines.

[apaansihnih]

Hi there, This is the best video with explanation so far I have seen. I thought the biodigester is supposed to be anaerob process, isn't it? how come you can get an anerob process with the other pipe exposed to the air?

[BioEnergySustTechUF]

Sorry for the late reply. The liquid level within the digester is higher than where the pipes connect to the barrel so the only aerobic zone is a small section in each pipe which doesn't create any problems.

[HomeDistiller]

I'm very interested in your results.. i have just completed a 44 gallon digester for my home and was wondering about your findings about the output etc..

did you wright a paper on this? if so would you email me a copy?

[BioEnergySustTechUF]

Sorry for the late reply. We did publish a paper from this study. What is your email and I can send it to you.

[Pitinginatay]

@BioEnergySustTechUF me too I would like ot ask for the study if you would like to share
