Your Professional Ferrous Sulfate Heptahydrate Supplier
Ferrous Sulfate Heptahydrate (FeSO₄·7H₂O) is an iron-based inorganic chemical utilized primarily in municipal and industrial wastewater treatment processes. Supplied as a blue-green crystalline solid, it functions effectively as an active coagulating and precipitating agent for suspended solids and dissolved phosphorus.
Industrial water treatment operations require predictable chemical reactivity, strict batch-to-batch consistency, and robust logistics capabilities. Bulk procurement decisions rely on verifiable active content, physical crystal stability, and complete technical documentation rather than generic marketing claims.

Water Treatment Applications & Dosing Guidance
Coagulation and Clarification
Ferrous ions participate in hydrolysis and precipitation reactions, destabilizing colloidal suspensions and facilitating the aggregation of suspended matter.
Operational Insight: Optimal dosage depends on raw water pH, alkalinity, contaminant loading, and separation equipment performance. Jar testing is strongly recommended prior to full-scale dosing adjustments.
Phosphorus Removal
Ferrous sulfate reacts with dissolved phosphate to form insoluble iron-phosphate complexes, enabling efficient phosphorus removal in secondary or tertiary wastewater treatment stages.
Process Parameters: System engineers evaluate influent phosphorus levels, target effluent limits, and sludge handling capacity when specifying product grades.
Production Route and Quality Control
Commercial production utilizes structured industrial synthesis routes. The selected manufacturing pathway directly impacts the impurity profile, governed by the following workflow:
Raw Material Inspection → Synthesis & Reaction → Crystallization / Separation → Drying → Controlled Screening → Finished Inspection → Packaging → Batch Documentation
Repeat orders utilize established baseline parameters to maintain uniform performance across every production cycle.
Compliance and Sample Policy
Regulatory Compliance:
Products meet standard industrial export regulations, with full support for destination-specific chemical registration and testing requirements.
Sample Evaluation:
Laboratory test samples (typically 1 kg to 5 kg) are available for facility jar testing and baseline compatibility analysis prior to bulk container ordering.
Safety and Handling Guidelines
Personal Protective Equipment (PPE): Operators handling Ferrous Sulfate Heptahydrate must wear appropriate safety gear, including chemical-resistant gloves, protective goggles or face shields, a particulate respirator (dust mask) to prevent inhalation of fine crystals, and standard industrial workwear.
Safe Skin and Eye Contact Measures: In case of eye contact, immediately flush eyes with plenty of clean water for at least 15 minutes while lifting eyelids, and seek medical attention. For skin contact, wash thoroughly with soap and water; remove contaminated clothing and wash before reuse.
Inhalation and Ingestion Response: If inhaled, move the affected individual to fresh air immediately. If breathing is difficult, administer oxygen. If swallowed, rinse mouth with water and do not induce vomiting unless directed by medical personnel; consult a physician promptly.
Spill and Leak Containment: Isolate the spill area and prevent material from entering drains, surface water, or groundwater systems. Sweep up or vacuum solid spills carefully to avoid generating airborne dust, then collect the material into labeled, sealed containers for proper disposal or reclamation.
Safe Ventilation Requirements: Ensure adequate local exhaust ventilation or mechanical air movement in handling, mixing, and storage areas to keep airborne dust concentrations well below established occupational exposure limits.
Packaging, Storage, and Logistics
Storage Guidelines:
Store in cool, dry, and well-ventilated indoor areas. Keep packaging tightly sealed to prevent surface oxidation or moisture absorption.
Packaging Options:
Available in 25 kg woven polypropylene bags with inner liners, 50 kg bags, heavy-duty jumbo bags (FIBC), and palletized configurations optimized for container shipping.
FAQ
Q: What is the shelf life of Ferrous Sulfate Heptahydrate?
A: When stored in a cool, dry, and tightly sealed environment, the product maintains its stability for up to 12 months. Prolonged exposure to air and humidity may cause surface oxidation (caking or color change to brownish-yellow).
Q: Can you provide custom packaging for large industrial orders?
A: Yes, we accommodate custom packaging requirements, ranging from standard 25 kg bags to 1,000 kg jumbo bags, as well as customized palletizing and labeling to match your warehouse offloading systems.
Q: How does this product perform in cold weather environments?
A: As a solid crystalline product, it remains stable in cold storage conditions. However, solutions prepared on-site should be kept in heated or insulated tanks if freezing temperatures pose a risk to your dosing lines.
