Coagulants are used for treatment of all kinds of water
Coagulation is the oldest known water treatment method
In industry, coagulants are frequently used for water treatment
In drinking water production, coagulants remove particles, humic substances and colour
Coagulants produce healthy and enjoyable drinking water
Coagulants are used for treatment of all kinds of water

In addition to their role as inorganic coagulants, aluminium and iron salts are used to:

  • Accelerate the setting time of concrete (aluminium salts)
  • Add vital nutrients to animal feed compounds (iron salts)
  • Create pigments used in the paint and cosmetics industries (iron salts)
  • Effectively treat anaemia in human beings (iron salts)
  • Fill fire extinguishers (aluminium salts)
  • Fix colours on textiles (aluminium salts)
  • Manufacture cosmetics and anti-perspirants (polyaluminum chlorides)
  • Produce zeolites used as commercial adsorbents (aluminium salts)

Applications

Drinking Water
In order to protect our health, all drinking water must be cleared of pathogens and impurities before it is used.
Other Applications
In addition to their role as inorganic coagulants, aluminium and iron salts are used in many other applications.
Waste Water
To ensure the water does no harm to people or the environment when it is released, waste water must be treated to reduce the level of contaminants to acceptable levels.
Industrial Uses
For industry, coagulants provide a method of reusing water in a cost-effective way that does not comprise the industrial process.
Paper Industry
Inorganic coagulants are used in two critical parts of the paper production process: sizing and retention.

FAQs

What quantity of coagulant is required to provide clean water for a typical European?

The average European uses approximately 150 litres of water per day which equates to almost 55,000 litres per year. To treat this amount of waste water requires approximately 1.1 kilograms of inorganic coagulant per annum.
