IMPLEMENTATION TO INDUSTRY AND MUNICIPAL SECTOR THE COMPACT TRICKLE BED BIOREACTORS TECHNOLOGY TO ODOR AND VOCS REMOVAL

result in the formation of even more harmful products of complex transformations, as is the case with ozone, which is formed in the atmosphere by chemical reactions caused by solar radiation with the participation of VOC and NOx [5]. The World Health Organization (WHO) divides VOCs into very volatile organic compounds with a boiling point below 50–100°C (e.g., propane, butane), volatile organic compounds with a boiling point between 50–100°C and 240–260°C (e.g. formaldehyde, acetone, ethanol, toluene

USE OF COMPACT TRICKLE BED BIOREACTOR FOR THE PURIFICATION OF AIR FROM A VOC’s MIXTURE – PRELIMINARY RESEARCH

strains found in the wastewater and adopted to chosen pollutants. The gas-flowrate was 4.0 m3/h and VOC concentration in the gas phase was changed from 40 to 255 ppm. In the whole period of research the efficiency of pollutant removal was in the range 92-99%. The lowest result of efficiency was achieved in the 2nd day of research as a response of the highest concentration of VOC. Possible consequences of a violent pollutant overload and the time required for regenerating the microorganisms and

Breath Analysis for Medical Diagnosis

produce odor fingerprints. Furthermore, recent work has shown it is possible to modify the basic sensor materials to both improve their performance, increase their tolerance to factors such as water vapour interferance which often leave the sensor system de-sensitized to the gaseous biomarkers, and enhance their selectivity. It will be shown how it is possible to accurately quantify concentrations of VOC’s and make disease diagnosis from analysis of the collected data which compare

Thin Film Coated QCM-Sensors and Pattern Recognition Methods for Discrimination of VOCs

gas sensors with different chemical affinity towards VOC molecules. The sensitivity of the elaborated QCMbased sensors was evaluated by monitoring the frequency shifts of the quartz exposed to different concentrations of volatile organic compounds, such as; ethanol, benzene and chloroform. The sensors responses data have been used for the identification and quantification of VOCs. The principal component analysis (PCA) and the neural-network (NNs) pattern recognition analysis were used for the
