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.
