Advantages of the product

Exceptional Charge Neutralization and Bridging Efficiency

Our PDADMAC flocculant polymer features high cationic charge density and optimal molecular weight, enabling robust charge neutralization of negatively charged colloidal particles. Field tests demonstrate a 30–50% reduction in sludge volume and up to 20% decrease in chemical costs compared to conventional alum or iron salts, enhancing overall plant efficiency.

Versatile Application Across Multiple Industries

Feymer’s PDADMAC flocculant polymer is tailored to diverse sectors, excelling in municipal wastewater phosphate removal, pulp and paper retention, and oil and gas produced water treatment. It performs reliably under cold conditions, reducing the need for multiple chemical inventories and simplifying plant procurement and operator training.

Sustainable Solution with Reduced Environmental Footprint

Choosing our PDADMAC flocculant polymer aligns with environmental objectives. Being organic and biodegradable, it eliminates heavy metal residuals in sludge. Its high efficacy requires lower dosages, directly cutting landfill usage, greenhouse gas emissions, and helping clients achieve zero-liquid discharge targets.

PDADMAC flocculant polymer is a highly effective synthetic polyelectrolyte carrying high cationic charges, making it exceptionally adept at destabilizing suspended particles, colloids, and dissolved organics. At Feymer, we produce PDADMAC trusted globally in municipal and industrial facilities. Its core mechanism involves adsorption and charge neutralization, bridging particles into settleable masses that reduce turbidity below 1 NTU. Operating efficiently across varied pH and temperature ranges, it produces up to 85% less chemical sludge than alum, advancing sustainable water management.

Frequently Questions

What makes PDADMAC flocculant polymer different from other flocculants?

Unlike inorganic flocculants like alum, PDADMAC is an organic polymer with a high cationic charge density that acts through charge neutralization and interparticle bridging. This leads to quicker floc formation, lower dosages, and less sludge production. It operates over a wider pH range (2-12) without altering treated water pH, excels in cold water temperatures, and introduces no heavy metal residuals into sludge, making disposal safer and more environmentally friendly.
PDADMAC is applied by dissolving the polymer to a working solution of 0.5%-1% using clean water. Dosages range from 1-20 ppm depending on contamination. It requires rapid flash mixing (300-400 rpm) for uniform dispersion, followed by slow stirring to promote floc growth before settling. For sludge dewatering, it is injected directly before a centrifuge or belt press. Our technical team provides dosing skids and 24/7 support.

Customer Testimonials

Hattie Stiles
Feymer PDADMAC solved our oil-sands tailings challenge

Our facility deals with large-scale oil sand tailings requiring rapid water recovery. Since switching to Feymer’s PDADMAC flocculant polymer, we’ve witnessed unprecedented settling rates. The high charge density efficiently binds fine clay particles, producing dense underflow that allowed us to increase water recycling by 40% and reduce fresh water use. * Michael Thompson, Operations Director at Alberta Oilsands, Canada

Mattie Cason
PDADMAC boosts our biological treatment performance at municipal plant

We had persistence in phosphorous and small suspended particles at our STP. Feymer recommended their medium molecular weight CAT polymer. The result: effluent turbidity dropped below 2 NTU, and orthophosphate levels now remain under 1 mg/L without added metal salts. Their product runs reliably, and we cut our chemical sludge disposal by half. * Ingrid Larsen, Water Quality Manager for Copenhagen Utility, Denmark

Unmatched Cationic Charge Density for Enhanced Flocculation

Unmatched Cationic Charge Density for Enhanced Flocculation

Our PDADMAC flocculant polymer delivers exceptional charge density of up to 1000 meq/g DMC, ensuring rapid neutralization of diverse anionic contaminants. This property results in faster micro-floc formation and better control over settling dynamics. The high charge promotes efficient adsorption onto surfaces, making it possible to treat difficult waters containing fine clay particles, stable emulsions, and dissolved dyes. Clients appreciate that chemical pump throughput is significantly reduced due to lower doses needed, contributing to diminished operational costs and a smaller equipment footprint. In side-by-side jar tests, flocs formed are large, tight, and quick to dewater, meaning higher throughput rates for clarifiers and filters. We use real-time analytics from our AI system to fine-tune molecular characteristics, maximizing water clarity and minimizing sludge volume for consistent daily compliance.
