INDUSTRIAL PROCESS WATER (I.P.W.)

A specific apparatus is associated to each treatment.

 Preliminary treatments

  • Basins and wastewater collecting sewers

  • Buffer tanks (buffering before treatment)

  • Pumping stations

    • centrifugal pumps (immersed or not)

  • Removal of algae and plankton

    • for example in cooling water circuits with atmospheric cooling towers

  • Grit removal

  • Coarse and fine screening (bar screens or sieves)

    • with manually or mechanically cleaning system

    • with or without comminutor

  • Desilting

    • with or without air bubbling

    • combined or not combined with oil and grease removal

    • with or without sand classification (and eventually cleaning)

    • circular or rectangular tank (concrete, steel, synthetic material, …)

  • Oil removal

    • with or without air bubbling

    • combined or not combined with grease removal

    • with or without granular bed

    • circular or rectangular tank (concrete, steel, synthetic material, …)

  • Grease removal

    • with or without air bubbling

    • combined or not with oil removal

    • circular or rectangular tank (concrete, steel, synthetic material, …)

    • biological or physico-chemical treatment
