| Summary: | The anaerobic biodegradability of water from crude oil production coming from the extraction of light petroleum (APPL), medium petroleum (APPM) and heavy petroleum (APPP) was studied under thermophilic conditions. Three batch reactor of 500 mL capacity were mounted containing water from the patio of tank Ulé, Maracaibo. Initially the reactors were operated under mesophilic condition and then the temperature was in creased to a ratio of 1°C/día until reaching the temperature of 55°C Ó 1°C. The time of reaction in all the cases was of 24h. The pursuit of the systems was carried out by of the measured of the chemical organic demand (COD), volatile suspended solids (VSS) and total (TSS), alkalinity, pH, volatile fats acids (VFA), biogas produced, methane percent age in the biogas. The results show that the waters from crude oil production provide the nutritional requirements for the development of the anaerobic microorganisms. The biodegradability of the APPL was not improved when being treated under thermophilic condition. It was a contrary case with the APPM and APPP. On the other hand, the biodegradability of the water from crude oil production is related with the composition of crude which ones the water is associated.
