FLOPAM AN956 SH anionic polyacrylamide is a high-performance anionic polyacrylamide (APAM) flocculant widely used in industrial solid-liquid separation processes. It belongs to the FLOPAM series of polyacrylamide products designed for applications requiring efficient flocculation, rapid settling, improved filtration, and enhanced water recovery.

Anionic polyacrylamide is a water-soluble polymer produced by copolymerizing acrylamide with anionic monomers. The polymer chain contains negatively charged functional groups, mainly carboxylate groups, which allow the polymer to interact with suspended particles, metal hydroxides, mineral particles, and colloidal materials.

The main working mechanism of FLOPAM AN956 SH is adsorption and polymer bridging. The long molecular chains attach to multiple particles simultaneously, connecting small particles into larger and stronger flocs. These flocs settle faster and can be separated more easily through sedimentation, thickening, filtration, or centrifugation.

Due to its high molecular weight and strong flocculation ability, FLOPAM AN956 SH anionic polyacrylamide is mainly applied in mining, mineral processing, wastewater treatment, sludge management, sand washing, oilfield operations, and environmental protection.

1. Application in Mining and Mineral Processing

The mining industry is one of the largest application areas for FLOPAM AN956 SH anionic polyacrylamide.

Mineral processing generates large amounts of fine particles that are difficult to settle naturally. These particles create highly turbid process water and require effective flocculation treatment.

FLOPAM AN956 SH is commonly used in:

• Tailings thickening
• Mineral slurry clarification
• Concentrate thickening
• Mine wastewater treatment
• Process water recycling
• Filtration improvement

In mineral tailings treatment, fine mineral particles remain suspended because of their small size and surface charge. When FLOPAM AN956 SH is added, the polymer adsorbs onto mineral surfaces and forms large flocs. These flocs settle rapidly at the bottom of thickeners, producing:

• Clear overflow water
• Higher-density underflow slurry
• Improved water recovery

Applications include:

Iron ore processing

In iron ore beneficiation plants, FLOPAM AN956 SH helps separate fine iron-containing particles from water after grinding and concentration processes.

Benefits:

• Faster settling of iron ore tailings
• Reduced suspended solids
• Improved thickener performance
• Increased recycling of process water

Copper, gold, and precious metal mining

During copper and gold processing, large quantities of fine mineral waste are produced. FLOPAM AN956 SH improves tailings sedimentation and helps recover water for reuse.

Coal washing

Coal preparation plants generate wastewater containing fine coal particles and clay. FLOPAM AN956 SH helps:

• Aggregate fine coal particles
• Improve clarification
• Increase clean water recovery
• Reduce environmental discharge

2. Application in Wastewater Treatment

Another major application of FLOPAM AN956 SH anionic polyacrylamide is industrial wastewater treatment.

Many industrial wastewater streams contain:

• Suspended solids
• Colloidal particles
• Mineral particles
• Metal hydroxides
• Organic contaminants

These particles are often too small to settle naturally. FLOPAM AN956 SH improves separation efficiency by creating larger flocs.

Typical industries include:

• Chemical manufacturing
• Paper and pulp production
• Textile processing
• Food processing
• Pharmaceutical manufacturing
• Metal finishing

The advantages include:

• Lower wastewater turbidity
• Improved solid removal
• Reduced chemical consumption
• Better sludge handling
• Improved effluent quality

In many treatment systems, FLOPAM AN956 SH is used after inorganic coagulants such as:

• Polyaluminum chloride (PAC)
• Aluminum sulfate
• Ferric chloride

The inorganic coagulant destabilizes suspended particles, while FLOPAM AN956 SH creates larger and stronger flocs.

3. Application in Sludge Thickening and Dewatering

Sludge treatment is another important field for FLOPAM AN956 SH anionic polyacrylamide.

Sludge generated from industrial and municipal wastewater plants contains a large amount of water. Efficient dewatering is necessary to reduce transportation and disposal costs.

FLOPAM AN956 SH can improve:

• Gravity thickening
• Belt filter press performance
• Vacuum filtration
• Centrifuge dewatering
• Filter press operation

The polymer helps by:

1. Neutralizing particle surface interactions.
2. Connecting fine solids into larger flocs.
3. Releasing trapped water from sludge structures.

The results include:

• Higher sludge cake solids
• Better filtration speed
• Lower moisture content
• Reduced sludge volume

This makes FLOPAM AN956 SH valuable in wastewater plants where sludge disposal costs are significant.

4. Application in Sand Washing and Aggregate Processing

The construction aggregate industry produces wastewater containing:

• Fine sand particles
• Clay particles
• Silica dust
• Suspended minerals

Without treatment, these particles remain suspended and create muddy wastewater.

FLOPAM AN956 SH anionic polyacrylamide is widely used in:

• Sand washing plants
• Quarry wastewater treatment
• Aggregate recycling systems

Its functions include:

• Accelerating settling in sedimentation ponds
• Improving water clarification
• Recovering valuable fine particles
• Reducing fresh water consumption

Benefits for sand washing plants:

• Cleaner recycled water
• Higher production efficiency
• Lower wastewater discharge
• Reduced environmental impact

5. Application in Oilfield Industry

High molecular weight anionic polyacrylamide products such as FLOPAM AN956 SH can also be applied in oilfield operations.

Enhanced Oil Recovery (EOR)

In polymer flooding, polyacrylamide is injected into reservoirs to increase water viscosity.

The purpose is:

• Improving sweep efficiency
• Reducing water channeling
• Increasing oil displacement

FLOPAM AN956 SH helps control the mobility ratio between injected water and crude oil, allowing more oil to be recovered.

Produced Water Treatment

Oil production generates produced water containing:

• Suspended solids
• Oil droplets
• Fine particles

FLOPAM AN956 SH can improve:

• Oil-water separation
• Clarification efficiency
• Solid removal
