The key tasks are to:

  • T3.1 Collect samples after each unit process of the sludge treatment line, analyse for ECs and develop a summary of frequency of detection and maximum concentrations detected of the analyzed ECs from the bio solid treatment train and sites of disposal of bio solids;
  • T3.2Analyze groundwater samples for screened ECs near land applications of bio solids;
  • T3.3Investigate the effect of SRT, HRT, temperature, sludge characteristics, and compounds’ bioavailability on ECs;
  • T3.4Evaluate removal pathways of screened ECs, primarily EDCs, in WTPs ;
  • T3.5Investigate transformation of ECs in rotary drum composting at various C/N ratios, prior to application in agricultural lands.
