[Digestion] Technology provider required for Bolivian project

Sun Jan 8 19:22:23 CST 2012

hi wolfi am living in cochabamba, and i think i konw the project. we proposed a pilot project with the local goverment to develope a solution for that slaughterhouse, but due to administrative problems of the local goverment we couldnt star the pilot project in 2011. we hope to doit on 2012.our idea is to use an UASB as pretreatment and later aserial of tubular digesters. the problem in these cases in bolivia is the mantainance of the pumps for the uasb, that the is no real secuity asbout their operation by the operators. that is the idea of the pilot project, to prove the operation of the punps, and to prove the tubular digesters as low tech (no agitation, no heating).i hope that the local goverment of cochabamna reactivate this pilot project.also, we are beginnign a siumilar project in Tiquipaya (20km from cochabamba) with a 25 cattle per day slaughterhouse. the experiments will begin to run this month.
the problems are dependet of the size of the slaughterhouseusually the use 1000 liters of water per cattle30 kg of rummen per cattle15 liters of blood per cattle
in big slaughterhouse they separte the solids (rumen and manure)  and aslo the waste water mixed with blood  (red line) to that one mixed qith rummen (green line)... so finally yo can make water treatment by AD. In cochabamba now they are implements a compost factory, and that should be the end of the rumen separated on the green line) in small slaughterhouse they do not separate anaything, and water+rummen+blood go together... this is a mayor problem because you have to treat the solids, and this more por HRT, so more liquid volumen od the digester, so more expensive. In tiquipaya (the small slaughterhouse) we are propousing to sepoarate the riummen and only treat the water-blood+greenline.

in Bolivia there are several experiencies on tubular digesters at household size. there are only a few of medium size digestera (greater than 12 m3) and there are just one digester of 70m3 liquid volumen to threat greay water from a millitary barracks. the digesters needed for the cochabamba 
slaughterhouse are much more bigger that the experiencie on the country, so that is why we propose a pilot project to theat the 10% of the waste, to afetr a year, propose a complete system for the 100% of the 
slaughterhouse  waste.
i hope this ideas helpswe keep in touchjaime

Dear Mr. Stang,
I have developed a biogas plant that accepts this kind of waste.  I would like get an idea of the amount of waste that would be available on a daily basis, and also if the potential user wants to convert all of it into biogas or if waste disposal is his main objective and if he would be satisfied to get a small quanity of biogas as a bonus.

Yours
A.D.Karve

Hi everybody

I have been contacted by a potential customer who is running a cattle slaughterhouse in Cochabamba, Bolivia. It appears that they have serious problems in handling the blood of livestock. They also have problems with the manure. They ask for information to start a biogas project, and other "by-products" that it (the AD) produces. The abattoir has a capacity of 250 cattle per day average. They would like to start this project as soon as possible.

I have no contacts in that part of the world hence my enquiry in this forum.

Is anybody interested taking on this lead? Have got another lead from Nigeria, also need a reliable contact for this region.

Cheers
