The poly aluminium chloride (PAC) is used for settling of solid particles present into drinkable waters and for the flocculation of civil and industrial effluents. It has also a high antibactericide effect, due to the presence of chlorine into the product formula, and can be utilized for large range of pH and with higher turbidity.
The main features of PAC are its high Al2O3 content and polymeric nature, which give rise to products of hydrolysis characterized by a high molecular weight and a large number of positive electric charges able to interact with the cellulose fibres and size, optimizing the sizing phase and the retention of fibres.
It is packed in 25/50 Kg HDPE/PP bags with inner liner
