HYPERFLOC CP 614, HYPERFLOC CP 615, and HYPERFLOC CP 618 PWG are cationic polymer flocculants belonging to the polyacrylamide (PAM) family, while PolyDADMAC (polydiallyldimethylammonium chloride) is a highly charged cationic organic polymer mainly used as a coagulant and charge neutralization agent. These products are widely applied in water treatment, wastewater clarification, sludge dewatering, industrial solid-liquid separation, and process water purification.

The main difference between cationic polyacrylamide products such as HYPERFLOC CP 614, CP 615, CP 618 PWG and PolyDADMAC is their working mechanism:

• HYPERFLOC CP series: Mainly performs flocculation through polymer bridging and charge neutralization.
• PolyDADMAC: Mainly performs coagulation through rapid charge neutralization due to its very high cationic charge density.

These products are often used individually or together in advanced water treatment systems.

1. Application of HYPERFLOC CP 614

HYPERFLOC CP 614 is a cationic polyacrylamide flocculant designed for applications requiring efficient sludge conditioning and solid-liquid separation.

1.1 Municipal wastewater sludge dewatering

One of the major applications of HYPERFLOC CP 614 is municipal sludge dewatering.

Waste activated sludge from sewage treatment plants usually contains:

• Fine biological solids
• Microorganisms
• Organic particles
• Extracellular polymeric substances (EPS)

These particles normally carry negative charges and remain suspended in water. HYPERFLOC CP 614 adsorbs onto sludge particles, neutralizes surface charges, and forms larger flocs through polymer bridging.

Benefits include:

• Improved sludge settling
• Higher sludge cake solids
• Better centrifuge performance
• Reduced sludge disposal cost
• Cleaner filtrate water

HYPERFLOC CP 614 is commonly used with:

• Centrifuges
• Belt filter presses
• Screw presses
• Filter presses

1.2 Industrial wastewater treatment

HYPERFLOC CP 614 is suitable for industrial wastewater containing high organic solids, including:

• Food processing wastewater
• Beverage wastewater
• Textile wastewater
• Paper mill wastewater
• Chemical manufacturing wastewater

The cationic polymer improves the aggregation of suspended particles and enhances clarification efficiency.

1.3 Paper and pulp industry

In papermaking, HYPERFLOC CP 614 can be used as:

• Retention aid
• Drainage aid
• White water clarification polymer
• Fiber recovery polymer

The positive charge of HYPERFLOC CP 614 attracts negatively charged cellulose fibers, fillers, and fines, improving:

• Fiber retention
• Paper quality
• Production efficiency
• Waste reduction

2. Application of HYPERFLOC CP 615

HYPERFLOC CP 615 is another cationic polyacrylamide grade designed for stronger flocculation performance in wastewater and sludge treatment.

2.1 Sludge thickening applications

In sludge thickening systems, HYPERFLOC CP 615 helps increase the concentration of solids before dewatering.

Applications include:

• Primary sludge thickening
• Secondary sludge thickening
• Biological sludge concentration

The polymer creates larger and stronger flocs, allowing more water to separate from solids.

Advantages:

• Faster sedimentation
• Reduced hydraulic loading
• Improved sludge handling

2.2 Food and agricultural wastewater

Food-related wastewater often contains:

• Proteins
• Fats
• Organic suspended solids
• Colloidal materials

HYPERFLOC CP 615 helps separate these materials efficiently.

Typical applications:

• Meat processing wastewater
• Dairy wastewater
• Sugar processing wastewater
• Vegetable processing wastewater

The polymer reduces turbidity and improves downstream biological treatment performance.

2.3 Mining wastewater treatment

Although anionic PAM products dominate mineral tailings applications, cationic polymers such as HYPERFLOC CP 615 can be useful where the slurry contains negatively charged organic or fine suspended materials.

Possible applications:

• Mineral processing wastewater
• Concentrate filtration
• Fine particle separation

3. Application of HYPERFLOC CP 618 PWG

HYPERFLOC CP 618 PWG is a higher-performance cationic polyacrylamide product designed for demanding solid-liquid separation processes.

The "PWG" grade designation is commonly associated with products intended for potable water and wastewater treatment applications, where consistent polymer performance is required.

3.1 Drinking water clarification

HYPERFLOC CP 618 PWG may be used as a polymer aid in water clarification systems.

Applications include:

• Surface water treatment
• River water clarification
• Reservoir water treatment

It improves:

• Suspended solids removal
• Turbidity reduction
• Settling efficiency

It is often combined with inorganic coagulants such as:

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

The inorganic coagulant destabilizes particles, while HYPERFLOC CP 618 PWG creates larger settleable flocs.

3.2 Municipal wastewater treatment

HYPERFLOC CP 618 PWG is widely applicable in:

• Primary clarification
• Secondary clarification
• Sludge dewatering
• Sludge thickening

It provides:

• Strong floc formation
• Improved sludge capture
• Better water release during pressing

3.3 Industrial process water

HYPERFLOC CP 618 PWG can be applied in industries requiring efficient separation of suspended solids:

• Power plants
• Chemical plants
• Refineries
• Manufacturing facilities

It helps recover process water and reduce wastewater discharge.

4. Application of PolyDADMAC

PolyDADMAC is a high-charge-density cationic polymer coagulant. Unlike polyacrylamide flocculants, PolyDADMAC mainly works through rapid destabilization of colloidal particles.

Chemical name:

Polydiallyldimethylammonium chloride (PolyDADMAC)

4.1 Drinking water treatment

PolyDADMAC is widely used in drinking water clarification.

Functions:

• Neutralizes negative particle charges
• Improves coagulation
• Reduces turbidity
• Enhances filter performance

It is commonly used with:

• PAC
• Alum
• Ferric salts

4.2 Wastewater coagulation

PolyDADMAC is highly effective for wastewater containing:

• Organic colloids
• Suspended solids
• Dyes
• Oil emulsions

Industries include:

• Textile dyeing
• Printing
• Paper manufacturing
• Petroleum processing
• Chemical production

4.3 Algae removal

PolyDADMAC is frequently used for algae control in water treatment.

It helps remove:

• Blue-green algae
• Organic colloids
• Natural organic matter

Applications include:

• Reservoir treatment
• Drinking water plants
• Industrial cooling water systems

4.4 Sludge dewatering aid

PolyDADMAC can be used before polyacrylamide addition.

A common treatment combination is:

PolyDADMAC + Cationic PAM

Process:

1. PolyDADMAC neutralizes sludge particle charges.
2. Cationic PAM forms large flocs.
3. Mechanical dewatering removes water.

This combination improves:

• Dewatering speed
• Filterability
• Sludge cake dryness
