Opaline™

A Drinking Water Solution

The Opaline™ solution : The sanitary safety for drinking water

Developed by Veolia Water Technologies for drinking water production, Opaline™ combines membrane technologies and activated carbon adsorption in order to remove:

  • pesticides,
  • Total Organic Carbon (TOC)
  • endocrine disruptors
  • micro-organisms,
  • turbidity,
  • taste and odours.

 

Features and Benefits

Opaline™ :

  • improves drinking water quality, with regards to safety, organoleptic parameters (taste, odours) and other factors (colour, ...),
  • guarantees a high quality potable water,
  • constitutes a reliable and safe solution,
  • reduces construction costs through a compact design.

 

Quality of the produced water:

  • Turbidity < 0,2 NTU
  • Pesticides < 0,1 µg/l
  • Parasites: 5 log removal
  • Bacteria: 5 log removal

 

 

Applications

Opaline™ is particularly well adapted for the treatment of :

  • Ground waters (including karstic waters) contaminated with pesticides and micro-organisms
  • Surface waters with low turbidity, contaminated by micro pollutants and micro-organisms, or as polishing.

 

References

Opaline™, as the ultimate solution to secure drinking water production, is already used in 24 plants around the world.

Operating Conditions

Opaline™ can be implemented in two different ways :

 

  • Opaline™ S :
    Sequential water treatment whereby the activated carbon stage is separate from the membrane filtration stage. Either GAC or PAC activated carbon can be used.
  • Opaline™ C :
    The activated carbon stage is combined with immersed membrane filtration. Powdered Activated Carbon (PAC) is used in this case.
