PFS (Polyferric Sulfate) – Water Treatment Coagulant Supplier from China

PFS (Polyferric Sulfate), also known as Poly Ferric Sulfate, is an efficient inorganic polymer coagulant widely used in wastewater treatment, industrial water purification, sludge treatment, and environmental protection applications.

PFS is a ferric-based coagulant that effectively removes suspended solids, turbidity, color, organic matter, phosphate, and certain heavy metal ions through coagulation and precipitation processes.

Compared with traditional ferric salts, Polyferric Sulfate provides faster floc formation, better settling performance, and wider application adaptability in many wastewater treatment systems.

We supply Polyferric Sulfate (PFS) from China for international water treatment companies, wastewater treatment plants, distributors, and industrial users.

Technical documents including COA, SDS, TDS, and product specifications can be provided according to customer requirements.

What Is Polyferric Sulfate (PFS)?

Polyferric Sulfate is a polymeric ferric salt used as a coagulant in water treatment processes.

When dissolved in water, PFS produces positively charged ferric hydroxide polymer species. These active components neutralize negatively charged particles and promote the formation of larger flocs.

The coagulation process helps remove:

Suspended solids
Turbidity
Organic pollutants
Color-causing substances
Phosphate
Certain heavy metal ions

Because of its strong oxidation and coagulation ability, PFS is widely used in complex wastewater treatment systems.

PFS as a Water Treatment Coagulant

The primary function of PFS is coagulation.

Many pollutants in wastewater exist as small particles or colloids that cannot settle naturally. PFS destabilizes these particles and promotes aggregation into larger flocs.

Main advantages of PFS include:

High coagulation efficiency
Fast floc formation
Excellent sedimentation performance
Strong turbidity removal
Good color removal capability
Effective phosphorus removal
Wide pH adaptability

PFS is commonly selected for wastewater systems requiring strong pollutant removal performance.

PFS for Wastewater Treatment

Wastewater treatment is the largest application of Polyferric Sulfate.

PFS is widely used in:

Municipal wastewater treatment
Industrial wastewater treatment
Chemical wastewater
Textile wastewater
Printing and dyeing wastewater
Paper mill wastewater
Food processing wastewater
Pharmaceutical wastewater

In wastewater systems, PFS helps improve:

Clarification efficiency
Suspended solids removal
COD reduction
Color removal
Sludge settling performance

PFS for Industrial Wastewater

PFS is especially suitable for industrial wastewater applications where complex pollutants need to be removed.

Common industries include:

Textile and Dyeing Industry

PFS can effectively reduce color and suspended pollutants in dyeing wastewater.

Paper Industry

PFS can be used for wastewater clarification and pollutant removal during paper production processes.

Chemical Industry

PFS helps treat wastewater containing organic pollutants and suspended solids.

Food Processing Industry

PFS can assist in removing organic matter and suspended particles from food industry wastewater.

PFS for Phosphorus Removal

One important application of PFS is phosphorus removal in wastewater treatment.

Ferric ions react with phosphate ions to form insoluble compounds, helping reduce phosphorus concentration in treated water.

This makes PFS useful in wastewater systems where nutrient control is required.

Applications include:

Municipal wastewater plants
Industrial wastewater treatment
Environmental protection projects

PFS vs PAC

PFS and PAC are both inorganic polymer coagulants, but their chemical compositions and application advantages are different.

PAC (Polyaluminium Chloride)

Aluminum-based coagulant
Widely used in drinking water treatment
Good turbidity removal
Broad market application

PFS (Polyferric Sulfate)

Iron-based coagulant
Strong color removal ability
Effective phosphorus removal
Suitable for complex industrial wastewater

The choice between PAC and PFS depends on water quality, treatment targets, and process conditions.

PFS vs PAM

PFS and PAM have different functions in water treatment.

PFS

Coagulant
Neutralizes particle charges
Creates initial flocs

PAM

Flocculant
Enlarges existing flocs
Improves settling and sludge dewatering

In some wastewater treatment processes, PFS is used first, followed by PAM to enhance solid-liquid separation.

Key Properties of PFS

Polyferric Sulfate provides:

Strong coagulation performance
Excellent color removal
Effective phosphorus removal
Good sedimentation performance
Lower sludge volume compared with some traditional iron salts
Wide application range
Suitable for industrial wastewater treatment

Storage and Handling of PFS

PFS should be stored in a dry and ventilated area away from moisture.

The product should be protected from contamination and excessive humidity to maintain quality and performance.

Proper storage conditions help ensure stable transportation and long-term storage.

Frequently Asked Questions About PFS

What is PFS?

PFS stands for Polyferric Sulfate, an iron-based inorganic polymer coagulant used mainly in water and wastewater treatment.

What is the CAS number of PFS?

The CAS number of Polyferric Sulfate is 10028-22-5.

What is PFS used for?

PFS is used for wastewater treatment, turbidity removal, color removal, phosphorus removal, and industrial water purification.

Is PFS a flocculant?

No. PFS is mainly a coagulant. PAM is a flocculant used to improve floc size and settling.

What is the difference between PAC and PFS?

PAC is an aluminum-based coagulant widely used in water treatment, while PFS is an iron-based coagulant often preferred for industrial wastewater, color removal, and phosphorus removal.

Can PFS be used with PAM?

Yes. PFS and PAM are often used together. PFS creates flocs, while PAM improves floc growth and sedimentation.
