Key Features & Advantages
✅ High 98% min purity, stable reaction effect
High‑content ferrous salt ensures reliable reduction and flocculation performance. Less impurity interference, guarantees consistent treatment results for downstream production.
✅ Strong reducing capacity
Effectively reduce toxic hexavalent chromium into harmless trivalent chromium, remove cyanide with removal rate above 95 %, handle heavy‑metal pollutants including lead and mercury, help enterprises meet wastewater discharge standards.
✅ Efficient coagulation & decolorization, low operating cost
Fast flocculation and sedimentation of suspended solids in sewage. Great decolorizing effect for printing‑dyeing and papermaking wastewater. Lower running cost compared with many alternative water treatment chemicals.
✅ Multi‑scene industrial compatibility
Versatile raw material for pigment, fine chemical, building material and gas purification industries. Used to produce iron‑oxide pigments, iron salts, cement chromium‑reducing additives and desulfurization catalysts. For HPF wet desulfurization process, desulfurization efficiency reaches over 99 %, cutting raw‑material cost by more than 30 %.
✅ Stable product performance & reliable bulk supply Reliable batch consistency; sufficient factory inventory to guarantee stable large‑volume supply, support continuous production for downstream factories. Qualified raw material for eco‑friendly cement production, no secondary pollution after reaction. Can be further processed into monohydrate ferrous sulphate to satisfy fine‑chemical production demands.
✅ Secure packaging for transit & storage
Inner PE liner isolates moisture and air, slows down oxidation deterioration. 25KG standard bagging convenient for loading, unloading, stacking and bulk logistics.
Main Applications
Wastewater Treatment
Flocculate suspended substances, reduce water turbidity, decolorize textile & paper‑making wastewater, remove phosphate to restrain eutrophication, detoxify hexavalent chromium and adsorb heavy‑metal ions for compliant effluent discharge.
Pigment Manufacturing
Core raw material for iron oxide red, iron oxide yellow and iron‑blue pigments. End‑products own stable color tone and strong adhesion for coating and building‑material coloring.
Green Cement Production
Reduce toxic hexavalent chromium inside cement clinker, improve safety performance of green cement, no secondary pollution during reaction.
Coal‑Gas Purification
Critical catalytic component for HPF wet desulfurization and decyanation. Also available for producing dry‑process iron‑oxide desulfurizer to lower production expenditure.
Fine Chemical & Other Industrial Uses
Produce iron salts, ink and electroplating additives to improve plating layer uniformity and metallic luster. Can be applied as mordant, tanning agent and wood preservative.
Storage & Handling Instructions
表格
| Category | Required Operation | Strict Prohibitions |
|---|---|---|
| Warehouse Condition | Store in cool, ventilated and dry dedicated warehouse; keep away from heat sources and direct sunlight; prepare leakage‑absorbing materials | Avoid water accumulation and humid environment |
