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 EU’s Industrial Emissions Directive (IED) sets out guidelines for the approval and control of industrial installations. The guidelines require an integrated approach and the implementation of best available techniques (BAT). BATs are the most effective techniques to achieve a high level of environmental protection, taking into account the costs and benefits. Revised BAT Reference Documents (BREF) are more prescriptive on which BATs should be used in order to provide more consistency across EU member states.

The first BAT (Best Available Techniques) Reference Document (BREF) on Large Volume Inorganic Coagulants (LVIC) was adopted in 2007. The BREF LVIC is scheduled for review in 2015. The process should last about three years.

INCOPA has established a BREF task force which will identify the data that needs to be collected. Members of the task force will also participate in the Cefic LVIC Working Group which will bring together experts from different industries.

Applications

Industrial Uses
For industry, coagulants provide a method of reusing water in a cost-effective way that does not comprise the industrial process.
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.
Paper Industry
Inorganic coagulants are used in two critical parts of the paper production process: sizing and retention.

FAQs

What are inorganic coagulants?

Inorganic coagulants are soluble salts which are used to purify drinking water and waste water from municipalities and industry. The term ‘inorganic’ simply indicates that the coagulants are not derived from living matter. Typically aluminium and iron salts are used to make coagulants.

These materials are abundant in the Earth’s crust and can also be derived from the recycling processes of industries such as steelmaking.

Inorganic coagulants provide a cost-effect, environmentally friendly method of water purification.
