Opaline™ S

Opaline™ S

Sequential water treatment whereby the activated carbon stage is separate from the membrane filtration stage.

Two possibilities to use the activated carbon :

  • fixed bed filter, with Granular Activated Carbon (GAC),
  • under a powder form (suspension), as Powdered Activated Carbon (PAC).

The level of performance being identical, the choice of GAC or PAC is decided on a case by case basis, depending on parameters such as the raw water quality, the configuration of the existing installation, etc...

Each step has a specific role:

  • Step 1 : removal of pesticides and organic matter by activated carbon,
  • Step 2 : reduction of the turbidity and removal of micro-organisms by membrane filtration.

To manage the PAC within Opaline™, Multiflo™ Carb and Actiflo™ Carb processes can be considered upstream to the UF membranes
