Aqualun® is commonly used in municipal and industrial water treatment plants and also for the treatment of drinking water.

Aqualun® is much less corrosive and dangerous compared to the use of other salts such as PAC, FeCl3, etc. and offers the same result. Aluminium sulphate works by neutralising negative charges by forming flocs that precipitate suspended solids, resulting in a lesser turbidity and removing TOC and BOD.

Aqualun® is also used in the paper industry, in fertilisers, in the manufacture of titanium dioxide-based pigments and in aluminas.
Aqualun® is a filtered solution, clear and low in iron.

It meets the specifications of the EN878 standard (chemicals used for the treatment of water intended for human consumption).

Numerous advantages


Aqualun® can be packaged in bulk or in smaller packages such as IBCs.
