Abstract

Advanced 1H NMR relaxometry based on fast Laplace inversion analysis combined with ATR-FT-IR spectroscopy, pH, electric conductivity and TDS (total dissolved solids) measurements were used to assess the purification process for chicken slaughterhouse wastewater. The 1H NMR T2-distribution (able to separate the effect of dissolved pollutants from undissolved pollutants), various integrated areas of IR spectra, the behavior of pH, electric conductivity and TDS show an efficient purification treatment for chemically treated water and evacuated water.
