A Robust Iron Salt for High-Performance Water Clarification

Ferric Chloride (FeCl₃) is one of the most effective and widely used inorganic coagulants in the global water treatment industry. As a powerful iron-based salt, it excels in turbidity removal, phosphorus precipitation, heavy metal reduction, and sludge dewatering.

Our premium-grade Ferric Chloride is supplied in highly concentrated liquid form under stringent quality controls to deliver consistent high iron content, low impurities, and exceptional coagulation performance. It provides rapid floc formation, excellent clarification, and reliable results even in challenging water conditions.

Ferric Chloride delivers rapid floc formation, dependable clarification, and strong multi-contaminant removal in a single treatment step.

Clarification

Removes suspended solids, colloids, turbidity, and color from raw water and effluent streams.

Phosphorus Removal

Precipitates soluble phosphate as ferric phosphate to help meet discharge limits.

Sludge Conditioning

Improves settleability and dewaterability while reducing disposal volumes and polymer demand.

How Ferric Chloride Performs

Ferric Chloride is used across coagulation, precipitation, adsorption, and conditioning applications where reliable solids separation and contaminant reduction are required.

01

Coagulation

Destabilizes colloids and suspended particles in raw water and industrial wastewater.

02

Phosphorus Removal

Precipitates phosphate as insoluble ferric phosphate to improve effluent compliance.

03

Heavy Metals

Coprecipitates metals such as arsenic, chromium, copper, lead, and zinc onto ferric flocs.

04

Sludge Dewatering

Improves sludge settleability and dewaterability while lowering disposal cost.

Ferric Chloride is also highly effective in H₂S odor control and industrial effluent treatment for food processing, pulp & paper, textiles, and metal finishing facilities.

Key Performance Advantages

Ferric Chloride performs reliably where water quality, solids loading, and treatment targets are demanding.

Cold Water Efficiency

Maintains strong coagulation in colder conditions where other coagulants may struggle.

Rapid Floc Formation

Creates robust, shear-resistant flocs that settle quickly and filter well.

Multi-Contaminant Removal

Combines turbidity, color, phosphorus, organics, and metal reduction in one step.

Cost Efficiency

Often requires lower doses than alum and can lower total sludge disposal costs.

Why Ferric Chloride Is Preferred

Ferric Chloride is valued for its broad applicability, strong performance, and ability to handle difficult water and wastewater conditions without complex process adjustment.

Broad pH Range

Effective over a wide operating range of 4.5–9.0, including cold-water applications.

Superior Floc Quality

Produces dense flocs with excellent settling and filtration behavior.

Versatility

Works in drinking water, wastewater, and industrial effluent treatment systems.

Operational Savings

Can reduce chemical consumption and improve dewatering economics in many plants.
