A proven, high-performance iron-based coagulant used for clarification, phosphorus removal, organic matter reduction, and improved solids separation in water and wastewater treatment.
Ferric Sulphate [Fe₂(SO₄)₃] is a proven, high-performance iron-based coagulant used globally for clarification, phosphorus removal, and organic matter reduction in water and wastewater treatment. Our premium Ferric Sulphate is produced under strict quality controls to deliver consistent iron content and excellent floc characteristics.
It is a preferred coagulant for municipal and industrial plants requiring effective particle destabilization, stronger floc formation, and improved solids settling. The product works across a broad pH range and supports stable treatment performance even when raw water quality varies.
Ferric Sulphate creates larger, denser, and faster-settling flocs that improve clarification, reduce turbidity, and support higher plant throughput.
Improves particle destabilization and settling for cleaner final water.
Supports phosphorus precipitation to meet stringent discharge and reuse limits.
Helps remove natural organic matter and reduce DBP precursor load.
Ferric Sulphate is a ferric iron salt formulated for stable, high-efficiency coagulation across a broad range of raw water qualities and plant conditions.
Fe₂(SO₄)₃ — ferric iron sulfate, a highly effective inorganic coagulant.
11–13% as Fe in typical liquid product, ensuring strong coagulating performance.
Reddish-brown acidic liquid or yellowish powder, ready for dosing in treatment systems.
Effective coagulation pH range of 4.0–11.0 with optimal performance between 5.0 and 7.5.
When added to water, Ferric Sulphate hydrolyzes to form ferric hydroxide flocs that neutralize negative colloids, capture suspended particles, and adsorb organics.
Ferric sulfate reacts in water to form ferric hydroxide species with strong coagulating activity.
Neutralizes negatively charged colloids, enabling particle destabilization and aggregation.
Suspended solids and colloids become trapped within larger ferric hydroxide flocs.
Adsorbs natural organic matter and other contaminant species that contribute to color and turbidity.
Produces larger, denser, and faster-settling flocs that improve clarification and filtration performance.
Result: better solids removal, stronger clarification, reduced turbidity, and improved plant throughput.
Ferric Sulphate excels in cold water, variable raw water quality, and high-organic loading scenarios, delivering strong floc formation and effective treatment efficiency.
Maintains strong coagulation even in colder operating conditions.
Produces flocs that resist shear and settle faster for higher clarification quality.
Improves settled and filtered water quality with reduced residual turbidity.
Supports lower filter backwash frequency and improved operational continuity.
High performance can reduce total coagulant usage for cost-effective operation.
Helps reduce sludge volumes and improve handling or conditioning performance.
Supports NOM removal and DBP precursor control for healthier treated water.
Low manganese and heavy metal impurities support potable water applications where approved.
Ferric Sulphate is applied across municipal, industrial, and wastewater processes where efficient coagulation, precipitation, and solids separation are essential.

We provide jar testing, pilot studies, storage recommendations, and dosing system design support. Typical dosages range from 10–100 mg/L depending on water characteristics. Storage should be in corrosion-resistant tanks with proper solvent compatibility and handling controls to preserve product stability and plant safety. This ensures reliable application and minimizes operational issues across the process lifecycle.
Our technical team can support jar testing, dosing recommendations, and plant design to match your raw water quality and treatment goals.
