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

Secondary flows management

• Service water production

• Sludge treatment

  • Thickening

    • by settling

    • by flotation

      • direct pressurisation

        HYDROFLOT Ed

      • indirect pressurisation

        HYDROFLOT Ei

    • on mechanical cloth filter

    • with or without chemical conditioning

  • Dewatering

    • Filter press

    • Rotary pressure filter

    • centrifuge

    • drying bed

    • drying pond

  • Storage before disposal (dewatered sludge storage tank)

  • Lime conditioning (sludge stabilisation and drying)

  • Disposal of dewatered sludge (containers, trucks, …)

• Reuse of filter back wash water

• Reagent dosing units (solids, liquids, gases)

• Compressed air production

• Treatment of the gases of the biological anaerobic treatments

  • Gas burner

  • Gas holder

  • Gas washer

  • Energy recuperation (heat, electricity)

• Deodorisation of the gases of the biological anaerobic treatments

  • By biological process

  • By chemical process (wash towers)

  • By activated carbon
