good day,
thanks for the guidance,i have read that methanogens are quite difficult to culture so i guess this will be a tough job,ill be doing a one man platoon..
thanks for the guidance it really shed light to my inquiries especially the sludge age part...

I happened to stumble along youre dialouge here while searching out industiral gas production rates as a fubnction of volatile solids destruction.

After reading your post's it seems to me that you need to broaden your scope in terms of obtaining a comprehensive understanding of Anaerobic digestion.

I currently operate two such bio-reactors in New Jersey and have operate dozens of others over the last thirty or so years.
I would suggest that you spend some time researching at the water Environment Fedration website and on their chat logs. http://www.wef.org/Home

By the way no reactor symply "dies" unless it has undergone some form of toxic shock most reactors will have tell-tale signs of loss of efficiency such as large swings in VA/ALK ratios or increased Co2 - Ch 4 ratios.

I fyoud like to talk about his further please email me at EXDIR@SMRSA.org and I will gladly arrange a telphone interview to get you started on the right foot.
I also have a ton of realtime data thatg may be of interest to you

Sirs,
i have finished a draft of my crtical review regarding the microbiology of anaerobic digesters..i wouldlike you to critique it for me if there is anything lacking...uhm its still a draft so anything can happen

im back with a new sets of problem i encountered with my research...
i have a problem with how to take samples of biogas....
my adviser suggests that we buy the biogas bag which cost dollars..
my partner suggest we put it in a plastic bag smilar to that of the one where dextrose are filled and used in hospitals
and i suggest that we use car rubber interiors but the problem is will this affect the biogas characteristics?

next we dont know the standards of the biogas component to compare our results with..

Hi artificial student,

Yes, you could purchase a biogas bag, or you could just purchase a large disposible plastic syringe. Once you put the cap on the end, you limit cross contamination.

Just a thought...  ;)

Eugene

good day eugene,


will the methane diffuse if we use plastic syringe or anything plastic?ive seen syringe made up of glass and metals but they are very costly all i am planning is to use a cheaper alternative any suggestions?im eying on rubber will it be okay?

Hi Artificial Student,

Yes, there is a possibility that a small amount of the methane will diffuse throught the plastic syringe. Usually this takes a great deal of time when the syringe is not pressurized. If you pressurize the syringe, my guess is that much of the sample will eventually pass around the syringe.

Sincerely,

Eugene

do you still need researchpapers on the matter?

I think I have some stuff that might help, just let me know if you are still interested.

Hello Polleke,

Yes, feel free to send a final copy to me and I will proofread it, along with providing helpful suggestions.  Usually, the more people that you can get to look at it, the stronger your paper becomes.

Good luck! ;)

Sincerely,

Eugene
