Colour

Removal

Colour in water has many origins and can be cumbersome to remove. Colour often derives from natural organic matter and is difficult to remove using conventional filtration methods. 

We specialize in understanding the cause for colour and designing the needed filtration to remove it. 

How it works

Features:
  • Engineered to fit

  • Flocculation testing

  • Fully automated

  • Compact design

  • Chemical dosing

Price:

The cost ranges depending on the size and complexity of the system. You should budget from R30 000 for a resin based residential system.

Add:

Integrate with your municipal source using our Water-to-Home controller.

Colour removal is achieved using one of two methods; scavenger resin filters or ultrafiltration (enhanced with coagulation). In order to correctly design your system we need:

  • A comprehensive water test of the water to be treated

  • The volume of clean water required

  • The description of the source of the water

Scavenger resin filters remove the colour by exchanges the organic particle for salt, thus trapping the colour inside the resin. Should you use a scavenger resin filter?

  • It can only remove colour caused by natural organic matter

  • Any metals (such as iron or manganese) will foul the resin

  • Brine regeneration needs to include periodic sodium hydroxide injection

  • Resin disinfection is key

  • Potable quality needs to be verified as chlorides are introduced

Should you use ultrafiltration and coagulation system? 

  • Works in combination with UF for smaller systems

  • Cheaper than resin

  • Difficult to maintain 

  • Clarification is required

  • Various particles origins can be treated
