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

The European Committee for Standardisation (CEN) did start the review of the classification of inorganic coagulants in 2013. INCOPA is cooperating with CEN and is providing input and comments on the new standards on behalf of the industry.


Industrial Uses
For industry, coagulants provide a method of reusing water in a cost-effective way that does not comprise the industrial process.
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.
Other Applications
In addition to their role as inorganic coagulants, aluminium and iron salts are used in many other applications.
Paper Industry
Inorganic coagulants are used in two critical parts of the paper production process: sizing and retention.
Drinking Water
In order to protect our health, all drinking water must be cleared of pathogens and impurities before it is used.


How is the use of inorganic coagulants regulated?

The quality of drinking water treated with inorganic coagulants is regulated according to standards published by the European Union and organisations such as the European Committee for Standardisation (CEN). Under these regulations, local water authorities are required to monitor and certify that drinking water is fit for human consumption.

All substances are registered under REACH (the European regulation which deals with the Registration, Evaluation, Authorisation and Restriction of Chemical substances).
