Our iron chloride finds its way in several applications such as waste water treatment, drinking water production, cosmetics and even in pharmaceutical products such as medicines.

Iron chloride is produced from chlorine; either virgin chlorine or chlorine from hydrochloric acid; and iron.
AkzoNobel supplies both ferrous chloride (FeCl2) and ferric chloride (FeCl3).

Waste Water Treatment

Phosphate has a fertilization effect in water which causes unwanted algae growth. Phosphates can be precipitated by dosing inorganic coagulants (Iron Chloride). Iron Chloride can also be used for separation of suspended solids from water. Chemical coagulation is an important process in water treatment for the removal of turbidity and particles as well as to enhance sludge dewatering.

Examples:

  • Removal of phosphate  
  • Flocculation in sewage works  
  • Elimination of hydrogen sulfide from digested sludge
  • Abatement of bulking sludge in activation units
  • Conditioning of sewage sludge
  • Conditioning of dump ground infiltrated water
  • Breaking of emulsion during treatment of processed water
  • Detoxification of chromate during conditioning of industrial waste water
  • Decolorizing of wastewater from textile industry
  • Preparation of cooling water
  • Conditioning of waste water from the smoke gas cleaning

Drinking Water Production

Water has to be purified against pathogens before it can be used for human consumption. And drinking water should preferably be colorless to be enjoyable. Coagulation with iron chloride is the most commonly used technique for removing particles, bacteria, virus, clay color and other pathogens. 

Examples:

  • Removal of suspended solids and colloids
  • Conditioning of filter backwash water

Other industrial applications

Examples:

  • Ingredient in products for crop protection
  • Raw material in pigments and paint production

Raw material for medicine to treat anemia.
