DAF Treatment

WPL DAF systems have been installed across Europe at municipal wastewater treatment works in many sludge thickening applications. These systems have been used most efficiently for minimising sludge waste from activated sludge and suspended growth biological treatment processes. Thickening applications include sludge from:
  • primary settlement tanks
  • trickling filters
  • final settlement humus tanks
  • aerobically digested sludge
  • sludge containing metal salts from chemical treatment
