MUNICIPAL WASTE WATER TREATMENT (M.W.W.)

Secondary biological treatments – Anaerobic processes

  • Free floating biomass reactor (complete mixed)

    ANAFREE

    • one or two steps

    • with or without sludge bed

  • Fixed biomass reactors
    ANAFIX

    • one or two steps

    • on support in movement

    • on support without movement

  • Secondary settling for clarification and sludge extraction:

    • settling tank with sludge scraper
      • centrally driving device
      • peripherally driving device

    • settling tank with sludge suction system

  • Sludge recirculation :

    • with or without intermediate thickening

    • by centrifugal, volumetric or Archimedes pumps
