There is disclosed a continuous process for the manufacture of aluminum sulfate by the reaction of sulfuric acid with an alumina-containing solid in an aqueous suspension. The reaction stream is passed into a continuous flow reaction zone that is maintained at a temperature controlled from 225° to 260° F. and under superatmospheric pressure, preferably, autogenic …
Aluminium Sulfate is the most common aluminium coagulant. It comes in a variety of solid forms, including block, kibbled, ground, as well as a solution. Aluminium sulfate (Al 2 (SO 4) 3) is frequently, but mistakenly, referred to as 'alum' in waterworks practice. It is a white crystalline solid in its anhydrous state.
Aluminium sulphate is the most widely used aluminium coagulant (Section 8.20).It is available in a number of solid grades such as block, kibbled or ground and is also available as a solution typically containing 8–8.3% w/w Al 2 O 3.In waterworks practice aluminium sulphate is frequently but incorrectly referred to as 'alum'.
The decanted solution of Aluminium Sulphate for the mixed process is then again taken to the Reactor and the required quantity of Sulphuric Acid is slowly added and after getting the temperature. The required quantity of Hydrated Alumina is slowly added keeping agitator rotating.

On heating, these ferrous sulphate crystals lose water and anhydrous ferrous sulphate (FeSO4) is formed. So you can observe that their colour changes from light green to white. On further heating, the anhydrous ferrous sulphate decomposes to form ferric oxide (Fe2O3), sulphur dioxide (SO2) and sulphur xide (SO3).
The next stage in the production chain is the processing of bauxite into alumina, or aluminium oxide - Al 2 O 3, - a white powder.The most common process for making alumina from bauxite is the Bayer process, which was first discovered over 100 years ago but is still in wide use today.
The method of producing aluminum sulfate includes the decomposition of aqueous suspension of aluminum hydroxide with sulfuric acid at a molar ratio of Al 2 O 3: SO 3 = 1: (2-2,6), the content in the reaction mass 18-20% Al 2 O 3. Sulfuric acid is metered in two stages: the first stage metered 10-20% of the total number of sulfuric acid with a ...

The addition of aluminium sulphate and fineness of grinding are responsible for accelerating the setting action of cement. The setting action of cement starts within five minutes after addition of water and it becomes hard like stone in less than 30 minutes or so.
The invention relates to aqueous suspensions of precipitated silica and of aluminum sulphate which have a pH lower than 4 and a solids content of between 10 and 50% by weight and which, after a period at rest of 48 hours, are in the form of a gel. The gel is reversible under low shear. The invention also relates to processes for the preparation of these suspensions and to their …
Aluminium sulphate, normally recognized as alum is a solid crystalline powder that is dissolvable in water. It includes over 17% alumina (Al2O3) and is produced from sulphuric acid and aluminium trihydrate. Aluminium sulphate is also obtained as an 18-hydrate Al2(SO4)3.18H2O. Both forms are soluble in water, non-combustible, and nontoxic.

At the beginning of the grinding process, some effects such as delamination, gliding and folding of the layers, and decrease in particle size were detected by SEM and XRD, resulting in a large increase in specific surface area, up to a maximum of ∼60 m 2 ·g −1. Marked changes in the structure take place between 30 and 32 mins grinding.
