Magnafloc 139 is generally classified as a high molecular weight anionic polyacrylamide (APAM) flocculant. Manufacturers usually do not publicly release the exact formulation data, but based on industrial classification, application behavior, and comparable APAM products, the typical technical range is as follows:

1. Hydrolysis Degree of Magnafloc 139

What Is Hydrolysis Degree?

The hydrolysis degree refers to the percentage of amide groups (-CONH₂) in polyacrylamide that are converted into carboxyl groups (-COO⁻).

For anionic polyacrylamide:

• Higher hydrolysis degree = stronger anionic charge
• Lower hydrolysis degree = weaker anionic charge

The hydrolysis degree directly affects:

• Flocculation performance
• Settling speed
• Sludge dewatering
• Compatibility with minerals and wastewater

Typical Hydrolysis Degree of Magnafloc 139

Magnafloc 139 is usually considered a:

Medium-to-high anionic flocculant

Its estimated hydrolysis degree is typically:

15%–30%

This range gives a balance between:

• Strong bridging capability
• Good settling performance
• Suitable viscosity
• Excellent mineral particle aggregation

Why This Range Is Important

Lower Hydrolysis Degree (<10%)

• Weaker charge
• Better for organic sludge
• Slower settling

Medium Hydrolysis Degree (15–30%)

• Balanced performance
• Strong bridging effect
• Excellent for mining and wastewater treatment

Very High Hydrolysis Degree (>35%)

• Strong electrostatic repulsion
• Sometimes poorer floc compactness
• More sensitive to water chemistry

Magnafloc 139 is designed to provide strong floc formation without excessive charge repulsion.

2. Molecular Weight of Magnafloc 139

What Is Molecular Weight?

The molecular weight of polyacrylamide indicates:

• Length of polymer chains
• Bridging capability
• Floc size formation

Higher molecular weight generally means:

• Larger flocs
• Faster sedimentation
• Better solid-liquid separation

Typical Molecular Weight Range

Magnafloc 139 is usually categorized as:

High or very high molecular weight APAM

Estimated molecular weight range:

12–18 million+

Some industrial sources may classify it closer to:

• 15–20 million

depending on production batch and testing method.

Why High Molecular Weight Matters

High molecular weight gives Magnafloc 139 several advantages:

1. Strong Bridging Performance

Long polymer chains connect many fine particles together.

2. Faster Settling

Large flocs settle rapidly in clarifiers and thickeners.

3. Improved Water Recovery

Especially important in:

• Mining
• Coal washing
• Sand washing

4. Better Sludge Dewatering

Produces drier sludge cake and reduces disposal cost.

Relationship Between Hydrolysis Degree and Molecular Weight

Both parameters work together:

Magnafloc 139 is optimized to combine:

• Medium/high anionic charge
• Very high molecular weight

This combination is ideal for:

• Fine mineral settling
• Industrial wastewater clarification
• Tailings dewatering

Typical Applications Based on These Properties

Because Magnafloc 139 has:

• 15–30% hydrolysis degree
• 12–18 million+ molecular weight

it is highly suitable for:

Mining Industry

• Tailings settling
• Copper flotation
• Iron ore processing

Sand Washing Plants

• Fine silica recovery
• Wastewater clarification

Coal Washing

• Coal slurry settling
• Thickener overflow clarification

Municipal Wastewater

• Sludge thickening
• Dewatering

Industrial Water Treatment

• Suspended solids removal
• Clarification systems

Important Notes

The exact values of hydrolysis degree and molecular weight may vary because:

• Different manufacturing sites use different formulations
• Regional versions may differ
• Measurement methods are not fully standardized

Most suppliers provide:

• Relative viscosity
• Charge density
• Performance testing results

instead of exact molecular weight values.

Summary

The typical technical characteristics of Magnafloc 139 are:

These properties make Magnafloc 139 an effective flocculant for:

• Mining
• Tailings treatment
• Sand washing
• Industrial wastewater
• Sludge dewatering
• Solid-liquid separation systems.
