Keywords:

  • fouling in microirrigation systems - and treated wastewater effluents;
  • major agrotechnical constraints - wastewater effluents in irrigation systems, fouling of pipes;
  • qualitative and quantitative aspects - of clogging-related phenomena;
  • quality of treated effluents - source of irrigation water;
  • emitter clogging, irrigation efficiency in microirrigation;
  • nitrogen and phosphorous species - dissolved organic carbon (DOC) and type of treatment employed;
