Abstract: Rapid measurement of the moisture content of dehydrated residues is a critical problem, the solution of which will increase the effi ciency of treatment facilities and optimize the process of applying fl occulants. The ability to determine the moisture content of dehydrated residues using a meter operating on the IR refl ectance principle was confi rmed experimentally. The most suitable interference fi lters were selected based on an analysis of the obtained diffuse refl ectance spectrum of the dehydrated residue in the range 1.0–2.7 μm. Calibration curves were constructed and compared for each fi lter set. A measuring fi lter with a transmittance maximum at 1.19 μm and a reference fi lter with a maximum at 1.3 μm gave the best agreement with the laboratory measurements.
