It is to be noted that fine solid particulates floating in water, do not settle down easily.
In the first place as dust forms suspension.
The particles are all similar in size and ionized, so, therefore, they have a similar charge resulting in them to get repelled each other and stay separate.
And because they're so small, the gravitational force acting on them is also very less.
What alum’s function? Alum has a negative charge and tends to disperse in water very fast and very well due to its colloidal effect.
This causes it to attract and join up with all of the suspended solids particles and neutralize them.
Particles lose their charge clump together into 'flocs’.
It potassium aluminiumsulphate or sulphate of potassium and aluminium, with formula KAl(SO4)2.
