Key Advantages
NSF Certified for Water Treatment Applications
For drinking water and clean water treatment projects, chemical safety and compliance are critical. BLUWAT PolyDADMAC is available with NSF certification, making it a trusted choice for water treatment applications where certified coagulants are required.
ZDHC Certified for Textile and Industrial Compliance
For textile wastewater and chemical supply chains, ZDHC certification supports customers who need more responsible chemical management. This is especially important for textile dyeing mills, washing plants, printing factories and brands that follow ZDHC-related requirements.
High Charge Density for Strong Coagulation
PolyDADMAC has a high cationic charge density, which helps destabilize suspended solids and colloidal particles in water. This improves floc formation and supports faster clarification.
Effective at Low Dosage
The product can deliver strong coagulation performance at relatively low dosage levels. Actual dosage should be confirmed by jar test according to raw water turbidity, wastewater composition, color intensity and treatment target.
Easy-to-Use Liquid Form
Liquid PolyDADMAC is easy to dilute, pump and dose. It is suitable for automatic dosing systems and daily operation in water treatment plants.
Can Be Used Alone or with PAC
BLU DA Series PolyDADMAC can be used alone as a primary coagulant or combined with inorganic coagulants such as Polyaluminium Chloride to improve clarification efficiency and reduce chemical cost in some systems.
Helps Reduce Sludge Volume
Compared with some traditional inorganic coagulant-heavy treatment systems, PolyDADMAC can help improve sludge dewatering performance and may support sludge reduction in suitable processes.
Wide pH Adaptability
PolyDADMAC can perform across a wide pH range, giving operators more flexibility in different water and wastewater treatment conditions.

Main Applications
Drinking Water Treatment
NSF certified PolyDADMAC can be used in drinking water clarification systems to help remove turbidity, suspended solids and fine particles. It is often used in combination with inorganic coagulants to improve floc formation and filtration performance.
Typical benefits include better clarification, improved turbidity reduction and more stable operation under changing raw water conditions.
Municipal Wastewater Treatment
In municipal wastewater treatment plants, PolyDADMAC can support primary clarification, phosphorus removal assistance, sludge conditioning and improved solid-liquid separation.
It can be used before sedimentation tanks, DAF systems or sludge dewatering processes depending on the treatment design.
Industrial Wastewater Treatment
Industrial wastewater often contains suspended solids, colloids, organic matter, oil residues or difficult-to-settle particles. PolyDADMAC helps destabilize these contaminants and improves coagulation efficiency.
It is suitable for wastewater from chemical plants, food processing, paper mills, textile factories, metal processing and other industrial facilities.
Textile Wastewater and Color Removal
With ZDHC certification, PolyDADMAC is especially suitable for textile wastewater treatment projects where chemical compliance is important.
It can help improve color removal, reduce turbidity and support better floc formation when used with decolorizing agents, PAC or PAM according to wastewater characteristics.
Paper Making and Pulp Wastewater
PolyDADMAC can be used in paper making systems and paper mill wastewater treatment to improve retention, charge neutralization and suspended solids removal.
Mining Wastewater
In mining applications such as coal, gold and diamond processing, PolyDADMAC can help improve clarification of process water, tailings water and other high-solid wastewater streams.
Sludge Dewatering
PolyDADMAC can support sludge conditioning and improve dewatering performance. It can be used before filter press, belt press, centrifuge or other sludge dewatering equipment according to the sludge type and treatment target.
How PolyDADMAC Works
Most suspended particles and colloids in water carry negative surface charges. These charges keep particles stable and prevent them from gathering together naturally.
PolyDADMAC provides strong positive charges. When added into water, it neutralizes the negative charges on suspended solids and colloids. Once the particles are destabilized, they can collide, form larger flocs and separate more easily by sedimentation, flotation or filtration.
This charge neutralization mechanism makes PolyDADMAC effective in many water and wastewater treatment systems.
Recommended Use Method
For water treatment, PolyDADMAC can be used together with Polyaluminium Chloride for treatment of turbid river water, tap water and other water sources.
When used alone, it is recommended to dilute the product to 0.5% to 5% concentration based on solid content before dosing.
The actual dosage should be determined by jar test because different raw water and wastewater sources may have different turbidity, color, organic content and suspended solids concentration.
For best performance, the dosing point and mixing speed should be carefully adjusted. The chemical should be mixed evenly with water and other treatment chemicals, while avoiding excessive shear that may break formed flocs.
Typical Treatment Process
For many water and wastewater applications, the process can be adjusted as follows:
Step 1: Check raw water or wastewater quality
Step 2: Adjust pH if necessary
Step 3: Dose PolyDADMAC or dose it together with PAC
Step 4: Mix rapidly to disperse the chemical evenly
Step 5: Slow mix to allow floc formation
Step 6: Separate flocs by sedimentation, DAF or filtration
Step 7: Optimize dosage by jar test and plant trial
For textile wastewater, color wastewater or complex industrial wastewater, PolyDADMAC may be used together with decolorizing agent, PAC and PAM to achieve better overall treatment performance.
