Abstract:

Pollution by VOC becomes increasingly alarming. The studies of their treatments are numerous; however, the biotreatments of the VOC were recently taken into account only. The study that we carried out showed the aerobic capacity of degradation of the MEK using a mixed culture of micro-organisms taken in the ventilation basins of the sewage treatment plant of El Menia Constantine. The biodegradation products are carbon dioxide and water. The study has been carried out at 30°C in a going interval of concentration in MEK from 500 to 2000 ppm. One noticed an increase of latency time as well as a reduction in the final concentration of the micro-organisms with the increase in the concentration in MEK. A strong reduction of performances of degradation was observed starting from 2000 ppm.

Keywords:

biodegradation, volatile organic compounds (VOC), mixed culture, methylethylcetone (MEK).
