Alum is used in the form of Aluminum Sulfate (usually) to remove particulates in water through flocculation to remove solids and some ions and allow them to be filtered or settled. The process is part of a treatment process and, properly managed, leaves little of the chemical components in solution.

In the present study, chitosan is being used as a flocculant along with alum as a coagulant for the removal of suspended impurities from pulp and paper mill waste water. For a particular dose of alum, varying concentrations of bio-flocculant chitosan were examined for maximum removal of suspended and colloidal impurities from wastewater.

Humans have long known that alum used can purify water, and its essence is also to use the agglomeration effect of alum in water. Refineries treat wastewater with high-efficiency coalescing agents. The air floatation method is to make the condensed oil beads and other impurities adhere to the floating small air bubbles and rise to the water surface to form scum, which can be easily scraped off.

1/4/2015, · It is reported that the alum sludge can be used to remove the hydrophobic dye from the textile wastewater at the removal efficiency of 88% . Alum sludge utilization for the removal of hydrophilic dyes is not recommended because the high solubility characteristics of hydrophilic dyes can create deterioration in the water quality during recycling ( Chu, 2000 ).
