With rapid industrial development and urban growth, wastewater pollution has become a serious challenge in both industrial production and daily life. Efficient and reliable water treatment chemicals are essential to meet discharge standards and reduce environmental risks.
PolyDADMAC is widely used in industrial wastewater, surface water, and municipal sewage treatment due to its strong coagulation performance and stable operation results. It is commonly applied in mineral processing wastewater, papermaking wastewater, oily wastewater from oilfields and refineries, and urban sewage systems. It is also used as a flocculant in drinking water treatment plants.
What Is PolyDADMAC?
PolyDADMAC is a cationic polymer supplied as a colorless to pale yellow viscous liquid. Its molecular structure provides a high positive charge density, which allows it to quickly neutralize negatively charged suspended solids, colloids, and organic matter in water. Through charge neutralization and adsorption bridging, PolyDADMAC forms dense flocs that settle rapidly, making solid-liquid separation more efficient and stable.
Application in Industrial Wastewater Treatment
In industrial wastewater treatment, PolyDADMAC is often used as a primary organic coagulant. It effectively neutralizes negatively charged colloidal particles and significantly reduces sludge volume when compared with traditional inorganic coagulants. It shows excellent performance in removing silt, clay, algae, bacteria, and fine suspended solids. At higher dosages, PolyDADMAC can also remove natural organic matter such as humic and fulvic acids, resulting in lower color levels and fewer disinfection by-product precursors in treated water.
Performance in Sewage Treatment Systems
PolyDADMAC delivers stable and reliable results in municipal and industrial sewage treatment. In papermaking wastewater, it efficiently flocculates fibers and fillers, allowing rapid clarification and easier downstream treatment. In printing and dyeing wastewater, it combines with dye molecules, disrupts chromophore structures, and improves color removal efficiency. Compared with conventional flocculants, PolyDADMAC requires a lower dosage while achieving better treatment performance, helping operators reduce chemical consumption and overall operating costs.
Oilfield and Energy Industry Applications
In oil exploration and production, PolyDADMAC is used as an additive in drilling fluids. It enhances drilling fluid stability and improves sand-carrying capacity, ensuring smoother drilling operations and reducing risks related to borehole collapse and fluid loss.

Papermaking Industry Uses
PolyDADMAC plays an important role in papermaking processes by improving paper strength and formation quality. It is used to control disturbing substances such as pitch and latex, especially in systems using mechanical pulp and coated broke. In short circulation systems, it enhances retention and dewatering efficiency. It is also applied to improve the performance of disk filters and flotation units, and to cationize fillers for higher filler retention rates.
Textile Industry Applications
In the textile industry, PolyDADMAC is used for antistatic finishing treatments. It helps improve fabric performance, reduces static buildup, and enhances overall product quality, especially during processing and handling.
