Advantages of the product

High Charge Density and Molecular Weight Optimized for Flocculation

Water treatment chemical PDADMAC from Feymer exhibits exceptionally high cationic charge density, enhancing its ability to neutralize negatively charged particles in water. Precise control over molecular weight ensures polymer chains bridge particles to form dense flocs that settle quickly. It maintains efficiency across a wide pH range (4-10) and high-temperature conditions.

Regulatory Compliance and Environmental Sustainability for Global Use

Feymer’s PDADMAC is manufactured in compliance with NSF/ANSI 60 certification for drinking water applications. Sustainable synthesis methods lead to reduced byproduct formation and lower residual monomers. It generates dramatically lower sludge volumes—sometimes up to 50% less—greatly lowering discharge and disposal costs for global clients.

Comprehensive Technical Support, Flexible Supply, and Scalability

Feymer’s seasoned engineers and chemists offer end-to-end technical support, from initial water quality analysis to on-site troubleshooting. Our production scale across Jiangsu and Anhui allows flexible supply options, meeting bulk and smaller volume demands while maintaining consistent quality and rapid delivery through strategic ports.

Water treatment chemical PDADMAC is an essential organic polymer with high positive charge density, enabling strong electrostatic attraction to negative particles like clay, silt, and bacteria. It aggregates fine particles into larger flocs easily removed by settling or filtration. Operating efficiently at low dosages, it produces less sludge that is easier to dewater. Feymer’s manufacturing advancements yield premium-grade PDADMAC with minimized DMDAAC impurities, complying with NSF/ANSI 60 for safe potable water production globally.

Frequently Questions

What is the working mechanism of PDADMAC in water treatment?

PDADMAC works through charge neutralization and interparticle bridging. Its cationic sites attract negatively charged contaminants, neutralizing their surface charge. As a long-chain polymer, it adsorbs onto multiple particles simultaneously, linking them into large, dense flocs that settle rapidly. It functions effectively across a pH range of 4-10, reducing the need for pH adjustment while removing natural organic matter and disinfection byproduct precursors.
Inorganic coagulants like alum require high dosages, increase ionic load, and generate large sludge volumes within narrow pH ranges. In contrast, PDADMAC is an organic polymer with high charge density independent of pH. It lowers overall chemical usage, eliminates residual metals in treated water, performs better in cold water, and reduces disinfection byproduct formation by better removing organic matter before chlorination.

Customer Testimonials

Maggie Guthrie
Highly Effective in Challenging Low-Turbidity Raw Water

Our municipal plant faced difficulties treating water with low turbidity and high color using alum. Switching to Feymer’s PDADMAC as a primary coagulant at 4 mg/L with a small alum dose produced strong flocs that settled well. We reduced sludge volume by 40%, extended filter runs by 60%, and consistently met finished water turbidity below 0.1 NTU. * James H., Operations Manager at a municipal water treatment plant in Michigan, USA

Lizzie Mcclellan
Excellent Performance in Industrial Wastewater with High COD and Oil Content

Our specialty chemical wastewater contained high organic solvents and suspended solids. Feymer recommended their high-viscosity PDADMAC at 15 mg/L with poly-aluminum chloride, systematically improving COD removal by 65% and oil and grease removal by 90%, allowing our biological stage to function properly. * Maria Santos, Environmental Engineer at a fine chemicals facility in Rotterdam, Netherlands

Unmatched Cationic Charge Density and Tailored Molecular Weight

Unmatched Cationic Charge Density and Tailored Molecular Weight

Our water treatment chemical PDADMAC stands apart due to proprietary synthesis allowing precise manipulation of charge density exceeding 5 meq/g and tailored molecular weight. This high charge requires fewer pounds of polymer, minimizing cost and toxicity while ensuring narrow molecular weight distribution. Advanced techniques guarantee exceptionally low residual monomer levels below 5 ppm, critical for food and drinking water applications. We offer customized grades for direct filtration, membrane pre-treatment, or conventional sedimentation. Furthermore, we utilize AI-machine learning models that correlate raw water metrics to predict ideal polymer grades and dosage. Our product remains stable in high TDS waters, such as unconventional oil and gas produced water, proving unmatched versatility across demanding industrial sectors.
Sustainable and Eco-Friendly Production that Supports Plant Operations

Sustainable and Eco-Friendly Production that Supports Plant Operations

Feymer integrates sustainability into manufacturing by utilizing a continuous PDADMAC production process that reduces energy consumption by 35% and waste byproducts by 15% compared to traditional batch methods. We have decreased our water footprint and utilize green energy sources to offer a lower carbon footprint product. Our proprietary catalyst system significantly reduces residual monomer formation, complying with strict global standards while supplying high-concentration 45% solutions to reduce packaging waste. At the user end, sludge production is markedly less than inorganic coagulant systems, promoting cost savings in dewatering and disposal. Holding ISO 14001 certification, we also offer a take-back program where unused polymers are recovered and repurposed, ensuring full compliance with environmental regulations.
