Description and use

Specially designed to control the development of scale in seawater distillation plants, Hydrex 9209 is based on a synergistic blend of phosphonates which is found to be more effective than other polymers at controlling carbonate and sulphate scale formation in sea water distillation units.

 

Advantages

  • Prevents formation of hard scale in seawater distillation units
  • Convenient liquid formulation suitable for automatic dosing using suitable dosing equipment
  • Cost effective concentrate
  • Effective at high temperatures
  • Performance surpasses other similar products: 
    HYDREX 9209's effectiveness in preventing scale from seawater surpasses that of other polymers such as sodium polyacrylate which requires nearly 3 times more time to achieve equal performance under the same conditions.
