Features & Benefits
- Product Highlights
- Commercially generated as by-product during the manufacture of Titanium Dioxide.
- Even though Ferrous sulfate is a by-product we have fully mechanized facility exclusively to manufacture FSH with min. 99% Purity.
- Used as a mordant in dyeing wool, in the manufacture of ink, in water purification as a substitute for aluminum sulfate, as a fertilizer, and as a feed additive.
- Copperas is also widely used as a coagulant in water treatment chemicals, and as a raw material for iron oxide pigments.
- Salient Features
- Highly Reactive due to High Solubility in Water.
- Excellent for Waste Water Treatment due to its strong De-Oxidizing attribute.
Applications & Uses
- Applications
- Uses
- Used as a micro-nutrient in Fertilizers & Animal Feed.
- As raw material in the production of Iron Oxide Pigments.
- As a Flocculant for waste water treatment of Printing, Dyeing and Electroplating due to its effective decolourization ability
- As a coagulant in the treatment of sewage waste and other water sources.
- As a reducing Agent for reduction of Chromate in Cement and removal of phosphates and Hydrogen Sulfide.
- As a Iron Fortifier for Feed Additive.
