Ferric Sulfate is a toxic, nonflammable chemical compound with the molecular formula Fe 2 O 12 S 3. Its CAS is . The dark brown or yellow chemical agent is produced by the reaction of sulfuric acid and an oxidizing agent. Ferric sulfate is used in different fields such as dentistry and dermatology.
Ironbased coagulants (ferric chloride and ferric sulfate) and aluminumbased coagulants (aluminum sulfate, polyaluminum chloride (PACl) and aluminum ... Sludge settling curves, dosesludge production ratios, and settling velocities were determined at optimum DOC removal conditions for each
Alum, ferric (aluminium sulfate) is produced by the reaction of sulphuric acid on bauxite a naturally occurring hydrated alumina ore having the approximate formula They are usually the double salts of ammonium, potassium or sodium sulphate with aluminium.
pickling baths for aluminum and steel. Ferric sulfate ... (Fe3+), and is excellent for drinking water production, wastewater treatment, phosphorus removal applications,
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 ...
Mar 01, 2016· 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
May 08, 2004· Ferric has wider effective pH range than alum, whose effectiveness decreases rapidly above pH 8. Important for precipitating metals at pH 9 or 10, maybe not relevant for TOC. Consider using ferrous sulfate (aka copperas). It is very cheap, (probably) more soluble than ferric, and you can aerate to ferric.
Product name: Aluminium Sulphate or Aluminum Sulfate Shape: Flakes or Granular or Powder. EINECS NO.: CAS No.: : Molecular Formula: Al2(SO4)3 Appearance: It is white or grey flake,particle or massive crystallization. Apt to cake after moisture absorption when laid in air for a long little green because of Fe2+,yellow when Fe2+ is oxided .
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).
used are in the form of alum (aluminum sulfate), sodium aluminate, ferric chloride, ferric sulfate, ferrous sulfate, and ferrous chloride. Chemical treatment is the most common method used for phosphorus removal to meet effluent concentrations below mg/L. Chemical Treatment Design Components Less complicated than biological
Ferric Sulfate Properties. The molecular formula for this chemical is Fe 2 (SO 4) 3 and its molecular weight is g/mol. It is slightly soluble in water, sparingly soluble in alcohol, and has negligible solubility in acetone and ethyl is insoluble in sulfuric acid and ammonia. Ferric sulfate is produced on a large scale through the reaction of sulfuric acid, an oxidizing agent ...
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 highcharged, moderate MM hydrolysis species.
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.

A process for the production of liquid ferric sulfate from finelydivided ferric oxide, sulfuric acid and water in a closed reaction vessel at temperatures . PROCESS FOR PRODUCING FERROUS SULFATE – M T Chemicals Inc. Generally speaking, this invention relates to a process for the production of ferrous sulfate from scrap iron.
Poly ferric Sulfate production process is the most advanced technology of spray drying method. Poly ferric Sulfate Solid Powder is easy to be damp when it is exposed in the air. Strong electric neutralization of colloidal substance in wastewater.
Aluminium sulphate is the most widely used aluminium coagulant (Section ).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–% w/w Al 2 O waterworks practice aluminium sulphate is frequently but incorrectly referred to as ''alum''.
Aluminum sulfate: Al 2 ... The approximate dry weight of solids removed per pound of dry alum and ferric sulfate are approximately and lb, respectively. ... The use of chlorine to oxidize organic color bodies may be limited due to the production of chlorinated organic byproducts, such as trihalomethanes. ...
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.
• 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 mg/L.
Poly Aluminium Chloride, Polyacrylamide, Polymeric Ferric Sulfate, Ferrous Sulfate, Ferric Trichloride
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 ...
