INCOPA is the European Inorganic Coagulants Producers Association
Inorganic coagulants are aluminium and iron salts; elements essential for water treatment, paper manufacturing, cement industry and fertiliser production. They are naturally occurring and afford safe drinking water to billions the world over.
INCOPA’s members manufacture inorganic coagulants (aluminium and iron salts) which are used to purify drinking water, treat wastewater, and create vital products such as cement, fertilisers and paper.
How long have inorganic coagulants been used in water treatment?
Alum has been used at least since Roman times for purification of drinking water (cf. Chemistry of Water Treatment – Samuel D. Faust, Osman M. Aly (1999)). It is also reported that Egyptians used alum coagulant as early as 1500 BC to reduce the visible cloudiness in the water.
In the modern times, London became the first city to mandate that drinking water should be purified using coagulants, after an outbreak of cholera in 1854. By the start of the 20th Century, scientists better understood the role of inorganic coagulants in water purification and their use spread worldwide. The treatment of waste water with inorganic coagulants started on a large scale in the 1950s.
