Advantages of the product

Superior Charge Neutralization and Flocculation Efficiency

Our Polydadmac is engineered with an exceptionally high cationic charge density, enabling rapid and effective neutralization of negatively charged colloids, suspended solids, and organic contaminants. This leads to faster aggregation and floc formation, significantly improving settling rates and filtration performance. The precisely controlled molecular weight ensures optimal bridging capabilities, enhancing the overall efficiency of the flocculation process. With effective dosage reduction compared to conventional coagulants, our Polydadmac lowers chemical costs and minimizes secondary pollution from sludge.

Versatility Across Multiple Industrial Applications

Polydadmac from Feymer is formulated to perform exceptionally well in a wide array of sectors, including pulp and paper, oil and gas, textile dyeing, chemical processing, and municipal and industrial water treatment. In the pulp and paper industry, it enhances retention and drainage, improving paper strength and reducing chemical usage. In oil and gas, it aids in the separation of oil-water emulsions and the clarification of produced water. For textile dyeing, our Polydadmac effectively removes dyes and heavy metals, enabling water recycling and reducing environmental impact.

Sustainable and Cost-Effective Treatment Solution

Our Polydadmac not only enhances treatment performance but also contributes to sustainable water management. By facilitating efficient solids separation and sludge dewatering, it reduces the volume of waste requiring disposal, lowering operational costs and environmental impact. Its use can significantly cut down the dosage of other chemicals, such as aluminum or iron-based coagulants, minimizing residual metal concentrations in treated water and sludge, thus reducing environmental toxicity. Moreover, our production processes are designed to minimize energy consumption and waste generation, exemplified by our commitment to green manufacturing.

Polydadmac, an acronym for polydiallyldimethylammonium chloride, is a linear and highly charged cationic polymer that plays a pivotal role in modern water treatment technologies. Its unique chemical structure, featuring quaternary ammonium groups on each repeating unit, gives it a permanent positive charge irrespective of pH, making it an extraordinarily versatile coagulant and flocculant. In the complex landscape of water pollution, where natural organic matter, industrial dyes, heavy metals, and colloidal particulates dominate, Polydadmac demonstrates remarkable efficacy. It works primarily through charge neutralization, compressing the electrical double layer of negatively charged contaminants, and inter-particle bridging, thereby promoting rapid aggregation into settleable flocs.

Frequently Questions

What is Polydadmac and how does it work in water treatment?

Polydadmac, or polydiallyldimethylammonium chloride, is a cationic polymer with a high density of positively charged quaternary ammonium groups. In water treatment, it functions as a coagulant and flocculant. The positive charges neutralize the negative charges present on suspended particles, colloids, and organic materials, thereby destabilizing them. This neutralization allows the particles to come together and form micro-flocs. The polymer also promotes the aggregation of these micro-flocs into larger, settleable flocs through a bridging mechanism. The resulting larger flocs can be removed more efficiently via sedimentation, filtration, or flotation processes. Polydadmac is particularly effective across a wide pH range (from 3 to 10) and at low water temperatures, where other coagulants like alum may be less effective.
Polydadmac finds extensive application in various industrial sectors. In the municipal water treatment sector, it is used for clarifying drinking water and treating sewage to remove organic pollutants and suspended solids before discharge or reuse. In the pulp and paper industry, it serves as a retention aid, drainage aid, and process chemical to improve paper quality and reduce chemical oxygen demand in wastewater. For oil and gas operations, Polydadmac is instrumental in treating produced water, breaking oil-water emulsions, and in drilling fluid formulations. In the textile and dyeing industry, it is applied to decolorize wastewater and remove anionic dyes, allowing for water recycling. Additionally, it is used in the chemical industry for process water treatment, in mining to consolidate fine tailings, and in food processing for water purification.

Customer Testimonials

Sarah Chen
Transformative Impact on Municipal Water Treatment Efficiency

Our municipality faced persistent challenges with treating raw water with high seasonal turbidity and algae blooms. Switching to Feymer’s Polydadmac has been transformative. The coagulant works effectively even in cold temperatures, which was our major bottleneck. We observed a significant reduction in turbidity levels from 15 NTU to below 1 NTU in final water, achieving a 95% removal rate. This not only meets but exceeds our state compliance standards.

Michael Lin
Reliable Solution for Industrial Wastewater Complexity

As a large-scale textile dyeing and finishing facility, our wastewater contains high concentrations of anionic dyes and varying pH levels. Polydadmac from Feymer has proven to be the most effective solution we’ve tried. It efficiently decolorizes the effluent, bringing color removal above 90% even under diverse dye mixtures. Additionally, we noticed a proportional reduction in chemical oxygen demand (COD), helping us meet stringent discharge permits with fewer post-treatment steps.
