Aluminium sulfate as coagulant for highly polluted cork

2007-9-5  This is the first part of a work on the chemistry of aluminium as coagulant in the treatment of highly polluted cork processing wastewater. The main aim of this first part was to determine the removal of organic matter measured by reductions in chemical oxygen demand (COD), polyphenols (TP), and aromatic compounds (A) that can be obtained using this physicochemical process.

Coagulants and flocculants fact sheet

Therefore, a trivalent aluminium ion will be 10 times more effective in charge neutralisation than the divalent calcium ion. Thus aluminium compounds are most often used as coagulants. Calcium salts, such as calcium sulphate or calcium chloride, can achieve coagulation but are substantially less effective than aluminium compounds.
