Evaluación de la producción de biol a partir de rumen bovino del Camal Frigorífico Municipal de Riobamba.

Abstract

The technical project allows evaluating the biol from the rumen of cattle at laboratory scale, to determine the treatment with greater yield and benefits. This raw material was submitted to a process of anaerobic decomposition for a period close to 42 days. Four formulations were practiced where it was identified that the nutrient content between them does not differ. Taking T2 as the formulation with greater efficiency when finishing in a shorter time its production of biogas, treatment made with the mixture of 50% water, 20% sieved Rumen, 20% pruning, 4.8% serum, 3.3% molasses, 1.9% ash, being smaller by nine 7 days to the treatment that follows it in the period analyzed. The bio digester obtained an efficiency of 96% during the fermentation process, being the net production of 57 liters of liquid biol value that is close to 60% of the weight at the end of the digestion processes. To determine the liquid volume of the experimental bio digester, it is used; the retention time of 42 days calculated based on the revised bibliography, and the total amount of charge is divided for the retention time obtaining a liquid volume of 0.1 m3. . With the data obtained from the daily load, it is estimated the amount 33000 liters of water and liquid rumen requiring a volume of 44m3 for the digester, it is so decided by the use of tubular bio digesters because based on the width of the tubular polyethylene plastic selected the same that has 6m of perimeter and l, 92m of same diameter that was available in the market. It was determined that the cost of one liter of biol from the rumen mixture and the other raw material is 0.40 $. For this, the use of tubular bio digesters is decided.
