Characterisation of wastewater using an electronic nose

Conductive and hydrophilic polypyrrole modified membrane cathodes and fouling reduction in MBR

“…It can be synthesized quickly from pyrrole via electrochemical or chemical oxidation reactions, and the conductivity can be maintained in MBR (where polyaniline could not, it had been tested in our lab). The PPy had been used in sensing/ion exchange membranes, electrochemical electrode and biomedicine [15][16][17][18][19]. A PPy-coated stacked membrane system has been used to separate lysine and aspartic acids under an electric field [20] and showed great potential, but there were few reports about the use of PPy in preparing conductive and hydrophilic membrane and in controlling membrane fouling in MBR.…”

Electronic noses for the continuous monitoring of odours from a wastewater treatment plant at specific receptors: Focus on training methods

“…Among these techniques, there is a growing interest towards the environmental applications of electronic noses. Since the first report of the design of an electronic nose using chemical sensors and pattern recognition in 1982 by Persaud and Dodd [1], there are nowadays several scientific publications concerning for example the application of electronic noses to the identification of specific environmentally important gases [2][3][4], to the detection of odour abatement system failure [5] or to the correlation of electronic nose responses to other parameters for the characterization of air or water quality, such as for example odour concentration [6] or BOD [7,8].…”

Development of a system for the continuous monitoring of odours from a composting plant: Focus on training, data processing and results validation methods

“…Most studies concern the application of electronic noses in the food industry [2][3][4][5]; in recent years, the possibility of applying electronic noses for the characterization of environmental odours has become an issue of increasing interest. There are a growing number of works regarding for example the application of electronic noses to the identification of specific environmentally important gases [6][7][8], to process control [9,10], to the detection of odour abatement system failure [11] or to the correlation of electronic nose responses to other parameters for the characterization of air or water quality, such as odour concentration [12] or BOD [13,14].…”
