The research objective was to develop a methodology for determining the total suspended solids concentration in wastewater based on the color indexes analysis. Determining the structure and properties of natural objects by processing its digital images has become widespread in soil science, since the soil colour is determined by its chemical and mineralogical composition. The material presented in the research can be considered as the initial steps in the development of soil science methods as applied to research objective.
Based on the RGB-technique for processing digital images of the liquids surface contaminated with suspended solids, the authors tried to quantitatively describe digital indexes depending on the contamination level. At the first stage, a forecast of unknown concentration values was made. Under normal illumination conditions (about 300 lux), based on five known concentration values, approximation functions were plotted for the colour indexes SI (saturation) and CI (coloration). Two unknown concentration values were forecasted: for the exponential function through the SI-index – 210.1 and 150.5 mg/l, and through the CI-index – 235.8 and 158.8 mg/l; for a linear function through the SI-index – 250.6 and 200.1 mg/l, and through the CI-index – 267.3 and 208.2 mg/l. The unknown experimental concentrations were 237 and 158 mg/L, respectively. At the second stage, the effect of illumination was studied on samples of apatite-nepheline factory wastewater. For two illumination ranges (300-335 lux) and (290-394 lux), as well as 7 concentration values for color indexes SI and CI, linear approximation functions were plotted in the index-concentration axes. |
