Product Description
Ferrous sulfate granules, the most widely circulated commercial form of ferrous sulfate, are predominantly represented by the heptahydrate variant (FeSO₄·7H₂O, CAS No.: 7782-63-0) in global markets. Appearing as pale blue-green free-flowing crystalline granules, they dissolve rapidly in water and glycerol. The product provides rapid reaction speed, wide working condition adaptability, absence of secondary pollution, and exceptional cost-effectiveness across industrial, agricultural, and wastewater treatment sectors.

Application
-
Wastewater Treatment:
Acts as an efficient coagulant and reducing agent for industrial and domestic sewage, offering outstanding decolorization for printing and dyeing effluents while removing phosphates, hydrogen sulfide odors, and heavy metals. -
Agricultural Sector:
Works as a high-efficiency iron fertilizer to correct leaf chlorosis, adjust alkaline soil pH, promote chlorophyll synthesis, and eliminate moss and lichen on lawns and tree bark. -
Industrial Manufacturing:
Serves as a prime raw material for iron oxide pigments, iron red, and tannic iron ink, as well as a textile dyeing mordant, wood preservative, and reducing agent for treating chromium-bearing wastewater.
