Ferrous sulfate heptahydrate, also known as iron(II) sulfate heptahydrate, is a chemical compound with the formula FeSO₄·7H₂O. It is a hydrate, meaning it contains water molecules within its crystal structure. It appears as blue-green crystals or granules and is soluble in water. It's used in various applications, including as a reducing agent, a source of iron, in water treatment, and in agriculture.
What are the advantages of our Ferrous Sulphate :
- Higher Iron Content and Purity
- Higher Fe2+ content (min 19%) means better coagulation efficiency.
- Low levels of contaminants like heavy metals ensure safety in treated water.
- Better Solubility and Dissolution Rate
- Proper crystalline structure ensures rapid dissolution.
- Uniform particle size improves dosing accuracy and mixing.
- Lower Impurity Profile
- Lower levels of contaminants like manganese, aluminum, or chromium.
