DETERMINATION OF THE POSSIBILITY OF MEASURING TRACE AMOUNTS OF WATER IN DEHYDRATED RESIDUES OF WASTE WATER BY DIFFUSE REFLECTION SPECTRA IN THE INFRARED REGION
Abstract
The measurement of the moisture content of dehydrated residues by rapid methods is an actual problem, the solution of which will increase the efficiency of treatment facilities and optimize the process of applying flocculants. As a result of the research, the possibility to determine the moisture content of dehydrated residues by a meter operating on the principle of receiving reflected radiation in the infrared wavelength range has been experimentally confirmed. Based on the analysis of the obtained diffuse reflectance spectrum of the dehydrated residue in the wavelength range of 1.0-2.7 μm, the most suitable interference filters were selected. Calibration equations were constructed for each filter set and a comparative analysis was performed. The best agreement with the laboratory measurements was obtained for the measuring filter with the transmittance maximum of 1.19 μm and the reference filter with the maximum at 1.3 μm.
