Description of key information

The aluminium sulphate  was determined to be 5.5 mm. 70% of the material has a particle size < 15 mm and   20% between   0.8 and 4 mm particle size.

Additional information

Under microscopic analysis, the largest single particle observed was15mm, however, sample agglomerations of >17 mm were also present.

The particle size distributions obtained from the analysis of Kemira Iberica S.A. is believed to consist of approximately 95% true particles and 5% agglomerated particles.
