aluminum sulfate production. Aluminium sulfate. Aluminium sulfate is a chemical compound with the formula Al 2 (SO 4) 3It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and waste water treatment plants, and also in manufacturing.

Oct 18, 2017· Substitutes include other aluminum and iron salts, like sodium aluminate and ferric sulfate, but these may or may not work. Proprietary products, instead of commodities, may offer a better solution. For example, a few products from ATS Innova's ATS 800 line are excellent substitutes for alum and ferric chloride:
Phosphorus Removal Metal salts (most commonly ferric chloride or aluminum sulfate, also called alum) or lime have been used for the removal of phosphate compounds from water. When lime is used, a sufficient amount of lime must be added to increase the pH of the solution to at least 10, creating an environment in which excess calcium ions can ...
pickling baths for aluminum and steel. Ferric sulfate ... (Fe3+), and is excellent for drinking water production, wastewater treatment, phosphorus removal applications,
ALUM (aluminum sulfate) is a nontoxic material commonly used in water treatment plants to clarify drinking water. In lakes alum is used to control algae, not by killing the algal organisms, but by reducing the amount of the nutrient phosphorus in the water. Like most other plants, algae requires phosphorus to live an reproduce.
Jan 16, 2018· Aluminum Sulfate – The most common and is often used with cationic polymer. Aluminum Chlorohydrate – Produces less sludge and is less corrosive than aluminum sulfate. Ferric chloride – Effective over a wider pH range than alum. Ferric sulfate – Often used as part of he lime softening process. Ferrous Sulfate – Less pH dependent than alum.
In the commercial line aluminium sulphate is also known as Alum. It is white in colour. The principal raw material for manufacturing of Alum are bauxite and sulphuric acid. Alum, ferric (aluminium sulfate) is produced by the reaction of sulphuric acid on bauxite a naturally occurring hydrated alumina ore having the approximate formula Al2O3.2H2O.
Less corrosive than ferric chloride. Lower sludge production. Still in the development stage. Not so widely used. Liu and Chin (2009), Wei et al. (2009a), Zhan et al. (2010, 2011), Cao et al. (2011) PFS: Made by partially neutralized (prehydrolyzed) ferric sulfate. Enhanced amounts of high-charged, moderate MM hydrolysis species.
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).
• Alum (aluminum sulfate), sodium aluminate • Calcium (lime) • Ferric chloride, ferric sulfate and ferrous chloride Chemical treatment is the most common method used for phosphorus removal to meet effluent concentrations below 1.0 mg/L.
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'.
Alum, ferric (aluminium sulfate) is produced by the reaction of sulphuric acid on bauxite a naturally occurring hydrated alumina ore having the approximate formula Al2O3.2H2O. They are usually the double salts of ammonium, potassium or sodium sulphate with aluminium.

Ferric Sulfate Properties. The molecular formula for this chemical is Fe 2 (SO 4) 3 and its molecular weight is 399.858 g/mol. It is slightly soluble in water, sparingly soluble in alcohol, and has negligible solubility in acetone and ethyl acetate.It is insoluble in sulfuric acid and ammonia. Ferric sulfate is produced on a large scale through the reaction of sulfuric acid, an oxidizing agent ...
Kinetic studies were made of the thermal decompositions of ferric sulphate and aluminum sulphate. The reaction product gases were swept from the samples. Cylindrical pellets prepared from chemically pure anhydrous powders were used, and mathematical corrections were made to relate the reaction rate to the area of the interface between the ...
