Opaline™

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.
