Characterization and treatment of organic constituents in landfill leachates that influence the UV disinfection in the publicly owned treatment works (POTWs)

- Leachates with a variety of age, location, waste acceptance and biological treatment.
- UV254 absorbance is more refractory than TOC in biological treatments.
- Fractionation into Humic acids, Fulvic acids and Hydrophilic fraction.
- Statistical analysis on the SUVA254 for the fractions shows that: HA > FA > Hpi.
- Biological treatment plus nanofiltration (1 kDa) is practical meet the UV requirement.
