As a leading manufacturer based in Qingdao, China, Qingdao Conqinphi Environmental Technology Group Co., Ltd. has specialized in producing high-quality PDADMAC (Poly(Diallyldimethylammonium Chloride)) since 2015. Our factory spans over 10,000-30,000 square meters, with annual exports valued at US$10-50 million. We supply this premium cationic polyelectrolyte to industrial wastewater treatment plants across the globe, including North America, Europe, Southeast Asia, and more. Our product ensures superior flocculation performance, helping you achieve clear effluent and efficient sludge dewatering.
Product Overview: PDADMAC is a water-soluble cationic polymer with high charge density. It is widely used as a primary coagulant or flocculant in industrial wastewater treatment, especially for removing suspended solids, organic matter, and colloidal particles. Its strong positive charge neutralizes negatively charged contaminants, forming large flocs that settle rapidly.
Key Features & Technical Specifications
- High Cationic Charge Density: 100% cationic, ensuring effective neutralization of anionic impurities in water.
- Broad Molecular Weight Range: Available in various viscosity grades to suit different treatment processes (low, medium, high).
- Excellent Solubility: Rapidly dissolves in water, forming a clear, stable solution without lumps.
- Wide pH Tolerance: Effective across pH 4-9, ideal for varying industrial effluent compositions.
- Low Dosage Requirement: Typically 1-10 ppm, depending on water quality, reducing chemical costs.
- Sludge Dewatering Efficiency: Significantly improves dewatering performance, reducing sludge volume and disposal costs.
- Non-Toxic & Environmentally Friendly: Safe for use in closed-loop systems, complies with international environmental standards.
- Customizable Packaging: Available in 200kg drums, 1000kg IBC totes, or bulk tankers.

Advantages for Industrial Wastewater Treatment
- Enhanced Suspended Solids Removal: PDADMAC effectively removes turbidity, TSS, and color from effluents of textile, paper, petrochemical, and mining industries.
- Reduced Chemical Sludge: Compared to inorganic coagulants like alum or PAC, PDADMAC generates less sludge, cutting down disposal costs.
- Improved Clarifier Performance: Works as a primary coagulant or as a coagulant aid alongside inorganic salts, enhancing settling rates.
- Oil & Grease Removal: Due to its strong cationic nature, it aids in the de-emulsification of oil-in-water systems.
- Cost-Effective Operation: Lower dosage required leads to overall savings in chemical purchasing and handling.

Frequently Asked Questions (FAQ)
-
Q: What is PDADMAC and how does it work in wastewater treatment?
A: PDADMAC is a cationic polymer that neutralizes the negative charge of suspended particles in water, allowing them to agglomerate into larger flocs that settle faster. It is highly effective for removing organic colloids, turbidity, and color. -
Q: What is the recommended dosage range for industrial wastewater?
A: Typical dosage ranges from 2 to 20 ppm, depending on the strength of the wastewater. We recommend performing a jar test to determine the optimum dosage for your specific application. -
Q: Can PDADMAC be used together with other coagulants like alum or PAC?
A: Yes, it is often used as a coagulant aid. It can be added after inorganic coagulants to enhance floc formation and reduce overall chemical consumption. -
Q: What is the shelf life and storage condition for PDADMAC?
A: Store in a cool, dry place away from direct sunlight and temperatures above 40°C. The typical shelf life is 12 months when stored properly. Avoid freezing. -
Q: Is this product safe to handle?
A: PDADMAC is considered non-hazardous under normal handling. However, it can be slipper due to viscosity. Use protective gloves and eyewear. Refer to our Safety Data Sheet (SDS) for detailed information. -
Q: Do you provide free samples for testing?
A: Absolutely! We offer free 1-liter samples for lab evaluation. Simply contact our sales team with your requirements. -
Q: What certifications does your company hold?
A: Our company is certified under ISO9001, ISO14000, OHSAS18001, and other international standards. We are committed to quality and environmental management. -
Q: How is the product packed and shipped?
A: Standard packaging includes 200 kg drums, 1000 kg IBC totes, or bulk tankers. We can also customize packaging according to your needs. Shipment is made from Qingdao port via sea or air.
