Ferric Chloride Solution 44% – Premium Inorganic Coagulant & Etchant
Product Overview
Ferric Chloride Solution 44% is a highly concentrated, dark brown liquid inorganic coagulant engineered for rapid solid-liquid separation and chemical precipitation. It acts as an exceptionally effective primary coagulant across a wide pH range, neutralizing the negative surface charges of suspended colloidal particles to form heavy, rapid-settling iron hydroxide flocs.
Optimized for high performance and heavy-duty industrial processing, Brand Chemical Supplies provides premium-grade Ferric Chloride Solution 44% tailored to meet the demanding requirements of South Africa’s mining, municipal wastewater, and metallurgical manufacturing sectors.
Key Applications
- Municipal Wastewater Clarification: Highly efficient at removing suspended solids, reducing Chemical Oxygen Demand (COD), and clarifying turbid water before filtration or discharge.
- Industrial & Mining Effluent Treatment: Excellently breaks oil-water emulsions and precipitates heavy metals (such as arsenic, lead, and chrome) from industrial wastewater streams.
- Phosphorus and Sulfide Removal: Chemically binds to dissolved phosphates to prevent eutrophication in natural water bodies, and precipitates dissolved sulfides to control hazardous odors and minimize concrete pipe corrosion.
- Sludge Conditioning: Conditions municipal and industrial sludge to optimize water release prior to processing in belt filters, centrifuges, or screw presses.
- Metallurgical Etching & Circuitry: Extensively utilized as an etchant in the manufacture of printed circuit boards (PCBs), photo-chemical machining, and copper etching.

Features and Benefits
- Rapid Sludge Settling: Produces dense, heavy iron flocs that settle significantly faster than traditional aluminum-based coagulants, enhancing plant capacity.
- Broad pH Operation: Performs highly effectively across a wider pH spectrum (pH 4.5 to 11) compared to alum, reducing the necessity for strict pre-treatment pH adjustments.
- Superior Odor & Corrosion Control: Actively binds volatile hydrogen sulfide gases, protecting downstream concrete infrastructure and eliminating foul odors.
- Concentrated Liquid Format: Eliminates the dust hazards and dissolution times associated with powder alternatives, allowing for precise, automated chemical dosing.
Safe Handling & Storage Guidelines
- Storage: Ferric Chloride is highly corrosive to metals. Store exclusively in UV-stabilized plastic, fiberglass (FRP), or rubber-lined steel containers. Keep tanks vented and stored in a cool, dry area away from direct sunlight and incompatible materials like strong bases or oxidizing agents.
- Handling: This product is strongly acidic and corrosive to skin and eyes. Wear comprehensive Personal Protective Equipment (PPE), including chemical-resistant overalls, nitrile or rubber gloves, face shields or splash-proof goggles, and rubber boots. Always ensure an eye-wash station is nearby.
