Application
  • Wastewater Treatment:
    Acts as a high-efficiency reducing agent and coagulant for industrial effluent and sewage, removing phosphates, odor-causing hydrogen sulfide, and heavy metals, while serving as a raw material for polymerized ferric sulfate flocculant.

  • Agricultural & Turf Management:
    Corrects iron chlorosis and iron deficiency in crops and plants, effectively eliminates moss on lawn turf, regulates alkaline soil pH, and boosts photosynthetic activity in compound fertilizer blending.

  • Industrial Manufacturing:
    Widely used as a reducing agent, polymerization catalyst, textile printing mordant, wood preservative, and essential precursor for producing iron oxide pigments (red/magnetic) and industrial ink.
