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

As all INCOPA members produce inorganic coagulants which are used in the treatment of water, they are affected by a number of different regulations governing water quality. Current issues of concern to INCOPA members include:

Also other water related directives and regulation do also have an impact:

Applications

Other Applications
In addition to their role as inorganic coagulants, aluminium and iron salts are used in many other applications.
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.
Drinking Water
In order to protect our health, all drinking water must be cleared of pathogens and impurities before it is used.
Paper Industry
Inorganic coagulants are used in two critical parts of the paper production process: sizing and retention.

FAQs

What happens to the sludge produced by inorganic coagulants?

When inorganic coagulants react with the impurities in the water, sludge is produced. The coagulant is removed from the water with the sludge. Good quality sludge, which has no trace of toxins, can be used in agricultural applications as fertiliser. Depending on its composition, sludge can also be used as biomass to produce biogas, incinerated, or placed in landfill.
