Our industry creates values
Inorganic coagulants are pivotal for safe drinking water and efficient wastewater purification. They
are produced in Europe, thus ensuring a reliable local supply.
Chemical water treatment is the most energy efficient water treatment technology and has a low carbon footprint.
Coagulants are essential for protecting human health and improving environmental performance. INCOPA members are committed to the highest product quality and environmental standards in Europe.
Chemical water treatment is the most cost efficient and state of the art technology. Coagulant use represents only 0.5% of the total cost of water purification (0.5€ on 100€, per person per year).
Our products, as well as their applications, contribute to the Circular Economy: thanks to
the use of inorganic coagulants 1/3 of the phosphorus used in Europe could be recycled.

1st to use Chemical Purification
The first to use chemical purification were the Egyptians around 1500 BC
71% of the Global Population
In 2015, 71% of the global population
(5.2 billion people) used a safely managed drinking water service
4 Billion People
We estimate around 4 billion people have access to drinking water treated with coagulants.
The next INCOPA General Assembly will take place in Athens on Friday,
Coagulants are widely used to purify drinking water and clean municipal wastewater.
Waste water is any water which has been used in an industrial process or household. This includes water used in the treatment of sewage or storm water.
In the paper industry they are used in the sizing and retention parts of the papermaking process.
Coagulants also have an important role in the treatment of industrial water.
There are also many other applications where aluminium and iron salts play an essential role.
How coagulants are made
Inorganic coagulants support the separation of dissolved and particulate impurities from the water. The raw materials are based on abundant natural resources (aluminium and iron) and high-quality by-products.
How coagulants work
Coagulants which are positively charged metal salts (Me+) react with the negatively charged colloids in the water to form bigger flocs.
Then the particles form larger, heavier flocs (flocculate).
Like larger particles, the flocs can be separated from the water using methods such as sedimentation, floatation or filtration.
