1. Understanding PolyDADMAC (Klaraid PC 1195)

PolyDADMAC, or poly(diallyldimethylammonium chloride), is a synthetic, strongly cationic quaternary ammonium polymer. It’s water-soluble and known for its high positive charge density—making it highly effective in coagulation and flocculation processes. YunCang ChemicalAtaman Kimya

Specifically, Klaraid PC 1195 (often referred to as PC1195 or PC 1195) is a Veolia-developed formulation—a medium to low/medium molecular weight liquid coagulant with strong cationic properties. Nur Kimya ArıtmaScribd

2. Mechanism of Action

At its core, the effectiveness of PolyDADMAC stems from two synergistic mechanisms:

• Charge Neutralization: Its high positive charge neutralizes negatively charged colloidal particles (e.g., suspended solids, organics), enabling them to attract each other and form flocs.

• Bridging Action: The polymer chains act like bridges, binding particles into larger aggregates.

Klaraid PC 1195 combines a relatively high molecular weight with high charge density—producing large, fast-settling flocs that enhance separation efficiency. ScribdNur Kimya Arıtma

3. Water Treatment and Clarification

a. Raw Water and Surface Water Clarification

Klaraid PC 1195 is commonly used as a primary coagulant to remove colloidal turbidity and color from raw or surface waters. Its performance is excellent in systems like lime softening and conventional clarification setups. Nur Kimya ArıtmaScribd

Advantages include:

• Reduced consumption of coagulant (lower dosage)

• Potential elimination or reduction of pH-adjustment chemicals due to pH-independent coagulation Nur Kimya Arıtma

• Improved operational efficiency in systems like mixed media filtration EPA

b. Filtration Aids & Inline Filters

Ideal for direct or in-line applications in low turbidity waters, Klaraid PC 1195 helps maintain cleaner filters and offers smoother flow dynamics. Nur Kimya Arıtma

4. Industrial Wastewater & Oil/Water Separation

One of PC 1195’s strongholds is in industrial wastewater from:

• Automotive manufacturing

• Steel production

• Hydrocarbon processing

Here, it's especially effective for oil/water separation, delivering clean breaks when used with:

• Dissolved Air Flotation (DAF) units

• Induced Air Flotation (IAF)

• API separators

It’s also widely used in latex emulsion destabilization and coagulation of fine particles for cleaner effluents. ScribdNur Kimya Arıtma

5. Sludge Dewatering & Residuals Control

PC 1195 aids in dewatering industrial sludges—producing sludge that settles faster and is easier to handle. This means:

• Lower sludge volumes

• Lower residual disposal costs

• Improved clarity in treated water and filtrate Nur Kimya Arıtma

This is particularly valuable for plants seeking to optimize total cost of operation while enhancing throughput. Water TechnologiesNur Kimya Arıtma

6. Broader Industrial Utility of PolyDADMAC

Beyond water treatment, PolyDADMAC finds broad industrial use:

• Papermaking: As a retention and drainage aid

• Textile Industry: Treating dye-laden and fiber-heavy wastewater by removing color and suspended matter YunCang Chemical

• Mining & Mineral Processing: Concentrating slurries, settling fine solids, boosting mineral recovery, and aiding flotation and inhibitor functions YunCang Chemical

Although these applications generally use PolyDADMAC in broader forms, they are consistent with the advantages Klaraid PC 1195 offers: charge neutralization, bridging, and efficient solids separation.

7. Certification & Safe Usage

Klaraid PC 1195P (often suffixed with “P”) is NSF-certified for use in potable water treatment at a maximum dosage of 10 mg/L. This certification demonstrates its suitability and safety for drinking water applications. NSF International+1

8. Summary of Key Application Areas

Here’s a structured overview of Klaraid PC 1195’s primary application areas:

9. Why Klaraid PC 1195 Stands Out

• High Charge, Enhanced Settling
  Its molecular design balances charge and size to generate robust, quickly settling flocs.

• Versatility Across Sectors
  Effective with various water types—raw water, industrial effluents, and potable systems.

• Cost-Effective
  Reduces chemical usage, pH adjustment needs, and sludge volume, all contributing to total cost savings. Nur Kimya ArıtmaWater Technologies

• Operational Efficiency
  Enhances performance in buoyancy-driven separators, filters, and dewatering units.

• Regulatory Compliance
  NSF certification ensures suitability for potable water treatment. NSF International+1

10. Final Thoughts

In essence, Klaraid PC 1195, a form of PolyDADMAC, is a powerful, widely applicable cationic liquid coagulant. Its strong charge, medium molecular weight, and flexibility make it a standout product in:

• Clarifying raw and industrial waters

• Separating oil from water

• Dewatering sludges

• Supporting filtration systems

• Complementing broader industrial and environmental uses (e.g. papermaking, textiles, mining)

• Treating potable water—with appropriate certifications
