Properties of Aluminium sulphate:

The industrial product is in the form of white flakes, granules, or blocks, with a light green colour due to the low-valent iron salt (FeSO4), and the surface of the product is yellow due to the oxidation of the low-valent iron salt.
The solid product of the water treatment agent is white, light green, or light-yellow flakes or blocks.
The liquid product is colourless and transparent to pale green or pale yellow.
