Pulp & Paper

Water is at the heart of the paper making process.

Water plays an important role in the paper  manufacturing process of which a key step is to  drain/dewater the pulp. To reduce the volume of water  used, significant efforts have been made in terms of  closing the circuits. The effluent also requires proper  treatment before being discharged into the  environment.

The inorganic coagulants and flocculants of Feralco Environnement (aluminium sulphate and polyaluminium chlorides of the Aqualenc® range) are central in the processes of water treatment applied by the paper industry. They allow to:

• prepare the water before applying it in the processes – raw water treatment
• monitor the anionic pollutants, fix sizing agents and improve the retention and drainage at the wet end of the paper machine
• treat the effluent before discharge into the natural environment
