Aluminium Sulphate. The aluminium sulphate produced by Feralco meets the most demanding standards on products used for the production of drinking water – NF EN 878 type 1, iron-free – by use of the finest raw materials. Aluminium sulphate is used primarily for drinking water production to precipitate the suspended solids and colloids.
found when using ferric salts, and as was found with ferric salts, aluminium salts result in a reduction in the pH, since for every 1 mg/ℓ of aluminium sulphate that reacts to produce a precipitate of aluminium hydroxide, 0.5 mg/ℓ of alkalinity (as CaCO3) is consumed (Water Quality and Treatment, 1990).

Mar 01, 2016· Ferric and non – ferric alum is marketed in various grades. The cheapest grade called "alum cake". Potash alum also known as alum alumen. Ferric alumin is aluminium sulphate containing iron obtained from the bauxite ore. Potash alum is prepared from its naturally occurring minerals such asalunite and ratinite. The Al2O3 percentage should ...
In the middle of the study, the coagulation/flotation process was modified by replacing the aluminium sulphate by ferric sulphate. At the same time, the filtration unit was enhanced by adding a sand filter unit before the activated carbon filtration and by changing new carbons on to the activated carbon filters.

The most important and the most valuable process developed by Dabster is the production of aluminum sulfate from various raw materials. Dabster owns the technology and know-how to produce aluminum sulphate from such raw materials like kaolin, bauxite and aluminum hydroxide. The process occurs under conditions of elevated temperature and pressure and takes place in several …
This paper addresses the application of coagulation-flocculation process using chemical coagulants, viz., aluminium sulphate (alum), polyaluminium chloride (PAC), ferrous sulphate and ferric chloride in combination with anionic polyelectrolyte.
Information @ a Glance. Contents on the CD Rom. Alum, in chemistry, is a term given to the crystallized double sulfates of the typical formula M2SO4·MIII2(SO4)3·24H2O, where M is the sign of an alkali metal (potassium, sodium, rubidium, caesium), silver or ammonium), and MIII denotes one of the trivalent metals (aluminium, chromium, or ferric iron).
Process for the production of aluminium sulphate, starting from the residual slimes of plants for the anodic oxidation of aluminium, according to the reaction: 2Al(OH)₃ + 3H₂SO₄ ----- Al₂ (SO₄)₃ + 6H₂O According to the process slimes (1) undergo a homogenizing treatment (2) which allows them to be subsequently conveyed up to and into the reactor (4).
Ferric, Alum or Lime-Why they are used in plants and how they can impact your process? Many plants add Alum, lime, or iron salts to the wastewater to remove phosphorus by sedimentation or clarification. This process can reduce the concentration of phosphate by more than 95 percent. Some plants use lime or Ferric sulfate for
iron sulphate (PAFS) coagulant using chemical grade aluminium sulphate Al2(SO4) 3.5H2O and ferric sulphate Fe2(SO4) 3.5H2O salts as the two primary raw materials. The coagulant was evaluated for the removal of colour and dissolved organic carbon from drinking water and showed similar or better performance to conventional coagulants.
Oct 31, 2019· The mass is now systematically extracted with water, and a solution of aluminium sulfate of specific gravity 1.16 is prepared. This solution is allowed to stand for some time (so that any calcium sulfate and basic ferric sulfate may separate), and is then evaporated until ferrous sulfate …
Aluminium Sulphate is decanted or filtered in wooden plate & frame press. The pressed Cake is washed with water and washings can be used in next batch. If pure Aluminium Sulphate is required, Barium Sulphide is added in the form of black ash to reduce Ferric Sulphate, so the Ferrous state effect precipitation of iron. The clear
