Marco:
Thank you for your interest. Depending on the waste type you can design an appropriate digestor to the energy necessities that you have. With but information (livestock type, I number of animals, area) one can make a small team draft.

above all a cordial Greeting my question is the following one: does eEs possible octener biogas used as matter prevail the waters servidad? I comment them to him for that I live in a city that has a serious problem of waters servidad and these waste will stop to the sea that which is a source of very big comçntiminacion, and if it is possible to take advantage of these waste to produce biogas and to minimize the problem of contamination

Thank you ahead of time

Hello Angel Towers. Of course that you can generate biogas with the served waters, but the first thing that you have to make it is to obtain the muds, this can make it an Engineer sanitarium. Leaving of the muds, we can help you.
Luck.

Dear Angel:

I differ of the colleague Infants, when requiring the mud of the Served Waters for their use in a Biodigestor. Alternative as the UASB (Upflow Anaerobic Sludge Blanket) they have been applied in Colombia, directly with Domestic Efluentes, being obtained very good results (when degrading more than the 75 of the Matter Organic present), being only used desarenadores, static sieves and Traps of Fatty as previous treatment. It is necessary to keep in mind that the domestic drainages are in fact solutions with a low organic load, for what you/they are a problem for conventional digestores (besides demanding enormous volumes) when trying to apply times of more retention to 15 days (a city can produce m3 thousands a day).
Exactly, this reason is the one that took to the development of new systems of Digestores, which have much smaller times of retention, and they reduce the initial investment. If bad I don't make a mistake, in Cundinamarca and in Peru, these systems are had for the treatment of domestic drainages, in Cundinamarca and in José Galvez, respectively.
Greetings.

ºBuenos days engineer chistrian Rodriguez, receive a cordial greeting on my behalf. Am I Marizadellys Díaz, student of engineering of petroleum and am I interested in knowing that possibilities would exist in applying the biodigestores technique to minimize the great quantity of heady urban waste toward the costs of the region, and if this application would be good to obtain bigger quantity of methane?

Very good Marizadellys:

The technology Anaerobia used for the organic degradation of Served Waters, is a technology highly recommended in warm countries, as Colombia (in which one comes already applying in but of one decade) or possibly in Venezuela (that possesses similar environmental temperturas to Colombia). The technology of this digestores type is known as UASB and it was developed in the 80s by the Dr. Lettinga (it is but, now an Institution that he/she administers its patent exists) in the University of Wageningen. In Brazil, several universities that maintain agreements with this university exist and they have consented to this technology. In Colombia, a company that shares the technology directly with the University of Wageningen exists. In the net it can find a sinnumero of cases that enlarged it technically already said. Even, digestores anaerobios exists for the efluentes of oil plants.

Greetings

Engineer Christian Rodriguez, I am really pleased and thanked by their answer. Their comment me aclarò certain doubts that had been presented. The previous question formulates it because at the moment I am making an investigation for my thesis it relates with the aplicaciòn of bacterias. The central focus of this investigation is to isolate one he/she tastes from bacterias coming from a biodigestor to laboratory scale and to try to accelerate its metabolism. Will you have infomaciòn of similar works that are carried out? That methods could be applied to accelerate the metabolism of the bacterias and this way to be able to diminish the times of retenciòn and to increase the producciòn of biogas? I wait their prompt answer. Thank you.

Hello Sr Christian Rodriguez.

The verda already him hey consulted before with regard to the biodigestores and in this opportunity since studies several concepts that he/she suggested me, him escrbio denuevo to ask him that I need biodigestores type and that it is efficient, hey full estudido about the Uasb and the Egsb, wanted to know which I need but independent of these 2 to generate biogas with the purines of cows milkmaids.

a hug and thank you.

good night engineer Christian Rodrìguez. The reason of my message is to clarify him that the message sent by Angel Towers was emitted by my. We are thesis partners and we are investigating jointly on the topic of biogas.
Once again I reiterate him my gratefulness for their answer. Success in their projects

Angel / Marizadellys:
Very pleased of to find young interested in developing investigation in our means, knowingly that in our countries this point is one of the thinest in the educational chore. Well, their topic is very interesting, although quite wide. To what you refer for stumps, in fact they are conglomerated bacterial that simbióticamente cohabits to save energy (expressed as electrons), in the estequiometria of the conversion of the Coal, Oxygen, Hydrogen and Nitrogen of the proteins, fatty and carbohydrates in Methane and CO2, through the hidrólisis, acidosis, acetanogenesis and metanogenesis. To be sincere, they are very few the investigators that have made an effort to identify the process in that you/they participate these bacterias, fully predicting in a global way their answer based on certain suppositions.
That that if I can tell them, it is that the times of retention have left diminishing in a dramatic way since it was possible to separate the Time of Hydraulic Retention of the Time of Cellular Retention (in the recirculation systems), there being you achieved to arrive until 4 hrs of TRH in front of the 15 to 25 days of conventional systems. For it, the best example is obtained of the granules formed in the digestores UASB. Maybe that it is a good beginning point (eye that the efficiency of some digestores is in the physical-chemical handling of the efluentes, before in the election of specific bacterias).
If there is something more in that can support them, with all pleasure.

Hernando King!
I like of tí knowledge. Good, the recommendation that I gave you was rather to analyze the efluente. Really, I hope you have followed that first step. The main reason of that recommendation, is for the possible presence of materials that you/they could force to a previous treatment of the efluentes. Alone as an example. If the stable uses some cellulose material as bed (sawdust, straw of rice, etc), this product could make collapse the system. This without mentioning the sands, ashy, antibiotics, etc... that they could be in the waste.
Now then, already discarded that first point, the election of the systems UASB (Upflow Anaerobic Sludge Blanket), and the EGSB (Expanded to Granulate Sludge Bed), they consist in that in the second, a distribution of the density of the granules is allowed (and of areas of more activity), in the column of the digestor (that by the way, it is much bigger to a digestor UASB). However, this technology depends a lot more than the systems of control of flow, because it is prone to the Chanelling when happening an increase of the pressure, and to be given the case that the flow passes without finding the resistance of the granules, and therefore, diminish its conversion efficiency. Eye that when thinking about the design of these digestores, they think about stationary systems, and therefore, he/she should stay a balance among the bacterial mass that is GENERATED and the size of the granules...
And it is not so easy to maintain it!
I hope it has served the previous explanation so that you make a guessed right decision.
Lastly, I reiterate you my support in your project. Even the Engineer Montanaro of the Forum Production of Biogas - you Plant Centralized and Simplified, it could lean on in the civil topic.
Greetings and successes!

Hello friends. I hope to be able to contribute to our only objective, to obtain biogas, an alternative energy and of reach for all. We are evaluating a team with optimization, of very low costs, and it is a work that is being carried out here for an agricultural farm in the Cusco-Peru. Anyway, the first work came out successful, today we are implementing these designs to scale of small farms. For any information, to write me. Thank you for everything.

good morning Christian. I have had the restlessness of manufacturing at laboratory level a biodigestor. My question is: when the gas begins to producirce, how the quantity is measured that is taking place. And another restlessness, the biodigestor, of what material it should be built, because I wanted to see if it is manufactured of iron, but not you if it produces him some inconvenience type to the reaction. Thank you.

good morning.
I am Wilman King, Falcon Venezuela, Cooperative The Mansion of the Pig.
We are in development of a project for a swinish farm, with capacity of 600 females to reproduce them for I.A.
My question is, if in my project I have a machine separadora of solids, it would not require of a biodigestor like format to avoid the contamination.
Much will know how to appreciate their restored.
Thank you.
