Micropollutants in water and wastewater

The progress in testing water quality highlights the presence of micropollutants in water which are having direct and indirect potentially chronic effects on water ecosystems. Especially municipal wastewater contains a wide range of micropollutants including pharmaceuticals and microplastiques that should be removed prior to discharge to the receiving water bodies.

Typical wastewater treatment plants based biological treatment will ensure some removal of micropollutants but are as such not designed for this. SUEZ however, anticipated increasing concerns about micropollutants and developed several treatment solutions to combat the issue.

Legislation is currently under development for the removal of micropollutants from wastewater and is expected to be implemented on EU wide basis in the coming years. Nevertheless, it is available in some countries like Switzerland. Meanwhile, the legislation is already in place for point sources such as hospital wastewater in Denmark.

Different methods and treatment solutions to remove micropollutants from wastewater

The choice of treatment technology depends upon micropollutants and molecules to be removed, the objectives sought and investments costs as well as costs of operations.

Dedicated solutions to tertiary filtration treatments:

  • Aquazur™ V – based on open sand filter
  • Compakblue™ – immerse disc filter
  • Ultrablue™ – ultrafiltration membranes
  • Ultrafor™ and Ultragreen™ – membrane bioreactor (MBR)

Dedicated solutions to refining treatments:

  • Ozonation
  • Pulsagreen™ – lamellar clarifier using a powdered activated carbon (PAC) pulsed blanket
  • Granular Activated Carbon filtration (GAC)

SUEZ has over the past 15 years been developing a range of solutions dedicated to micropollutant removal referred to as the Oxyblue™ range.

The Oxyblue™ solutions are based on ozonation to be implemented on existing plant either as an add-on (tertiary treatment) or integrated solution.
