Ferric Sulphate

ferric sulphate

Ferric Salts are used in many different municipal and industrial applications. In water and wastewater treatment operations, ferric salts are used as coagulants or flocculants for water clarification, odour control to minimize hydrogen sulfide release, for phosphorus removal, and as a sludge thickening, conditioning and dewatering agent.

DESCRIPTION Liquid Ferric Sulphate is a red-brown aqueous solution that is typically sold as a 50% or 60% strength solution, on a dry basis. Based on ferric iron (Fe+3) contents of 10% and 12% respectively for the two concentrations of liquid ferric sulphate, the formula for dry ferric sulphate would be Fe2(SO4)3•8.8H2O. The maximum concentration of ferric iron is approximately 13% in commercial liquid products.

Iron(III) Sulphate, also called ferric Sulphate, is an industrial scale commodity chemical compound, with the formula Fe2(SO4)3 and with iron in the +3 oxidation state. The colour of iron(III) sulphate crystals depends on the viewing angle: by reflected light, the crystals appear dark green, but by the transmitted light they appear purple-red. Anhydrous iron(III) sulphate is deliquescent, forming hydrated hydrogen chloride mists in moist air. It is rarely observed in its natural form, the mineral molysite, known mainly from some fumaroles.

Why is ferric Sulphate base?

Simply, except in the presence of free oxygen, copper will not react to any significant extent with hydrochloric acid which is the acid produced with ferric sulphate solutions. When ferric sulphate is dissolved in water the solution becomes strongly acidic as a result of hydrolysis.

Why is ferric sulphate used in water treatment?

Ferric sulphates are the coagulant of choice for many industrial and sanitary wastewater treatment applications, due to its high efficiency, effectiveness in clarification, and utility as a sludge dewatering agent. The chemical leaves slight residual colour and offers very good turbidity removal.

What neutralises ferric sulphate?

The solution must not be put down the drain because of residual copper ions left in it. To make it safe for disposal, you can add sodium carbonate (washing soda) or sodium hydroxide to it to neutralise it, until the pH value goes up to between 7.0 and 8.0, testing it with indicator paper.

Are Iron based coagulants hazardous?

CHEMICAL DANGERS: The substance decomposes on heating above 200°C producing toxic and corrosive gases including chlorine and hydrogen chloride. The substance decomposes on contact with water producing hydrogen chloride. The solution in water is a medium strong acid.

What is the use of Ferrous sulphate?

Ferric Sulphates are effective primary coagulants based on trivalent iron (Fe3+), excellent for drinking water production, wastewater treatment applications such as phosphorus removal, struvite control and sludge conditioning. The products also control the formation of hydrogen sulfide and prevent the formation of odour and corrosion. It is used in sewage treatment, in the dying of fabrics, and for many other uses.

Ferric Sulphate Other Uses

  • Used in anhydrous form as a drying reagent in certain reactions.
  • Used to detect the presence of phenol compounds in organic synthesis; e.g., examining purity of synthesised Aspirin.
  • Used in water and wastewater treatment to precipitate phosphate as iron(III) phosphate.
  • Used by American coin collectors to identify the dates of Buffalo nickels that are so badly worn that the date is no longer visible.
  • Used by bladesmiths and artisans in pattern welding to etch the metal, giving it a contrasting effect, to view metal layering or imperfections.
  • Used to etch the widmanstatten pattern in iron meteorites.
  • Necessary for the etching of photogravure plates for printing photographic and fine art images in intaglio and for etching rotogravure cylinders used in the printing industry.
  • Used to make printed circuit boards (PCBs).
  • Used in veterinary practice to treat overcropping of an animal’s claws, particularly when the overcropping results in bleeding.
  • Reacts with cyclopentadienylmagnesium bromide in one preparation of ferrocene, a metal-sandwich complex.
  • Sometimes used in a technique of Raku ware firing, the iron colouring a pottery piece shades of pink, brown, and orange.
  • Used to test the pitting and crevice corrosion resistance of stainless steels and other alloys.
  • Used in conjunction with NaI in acetonitrile to mildly reduce organic azides to primary amines.
  • Used in an animal thrombosis model.
  • Used in energy storage systems
  • Historically it was used to make direct positive blueprints.
  • A component of modified Carnoy’s solution used for surgical treatment of keratocystic odontogenic tumour (KOT)

What is the use of flocculant?

Flocculants, or flocculating agents (also known as flocking agents), are chemicals that promote flocculation by causing colloids and other suspended particles in liquids to aggregate, forming a floc. Flocculants are used in water treatment processes to improve the sedimentation or filterability of small particles.

Iron(III) Sulphate is harmful, highly corrosive and acidic. The anhydrous material is a powerful dehydrating agent.

Although reports of poisoning in humans are rare, ingestion of ferric sulphate can result in serious morbidity and mortality. Inappropriate labelling and storage lead to accidental swallowing or misdiagnosis. Early diagnosis is important, especially in seriously poisoned patients.

Removal of Suspended Solids and COD
You coagulate and flocculate effluent to remove the suspended solids from wastewater at the end of a manufacturing process. The coagulant changes the electrical charge of the suspended solids so they start to attract each other to form small particles. Flocculation brings these small particles together to form flocs, using mechanical processes (eg DAF) these flocs can be made to either rise or fall to allow them to be removed from the wastewater. Once these suspended solids and the COD values associated with them are removed, the clean effluent can then be let to sewer, potentially saving your company thousands of pounds annually in trade effluent charges.
