Applications for pulp & paper

Water is essential for the process of manufacturing paper. Over the past years great efforts have been made to reduce the amounts of water that are needed to make paper, by closing the circuits and treating the effluents used in the process before they are returned to the natural environment. 

The mineral coagulants and flocculants used at Feralco Iberia (aluminium sulphate and polyaluminium chloride) are applied in the wet end and the water treatment processes. They enable to:

• prepare the water before using it for manufacturing paper

• control the anionic pollutants, fix the sizing agents and improve wet end retention and draining.

• treat the effluents before they are returned to the natural environment
