1.1 Core Molecular Structure and Charge Characteristics
The product features a linear polymeric quaternary ammonium structure with a regular, stable molecular chain free from branched-chain impurities. It incorporates high-density, strong cationic groups, maintaining a stable charge density within the 50%--100% range. Upon entering the water, it dissolves rapidly and completely and disperses evenly without issues such as stratification, gelation, or precipitation. Its charge activity remains durable and stable, showing no rapid degradation due to changes in water temperature or quality.
1.2 Safety and Physicochemical Properties
This Cationic Polymer Water Treatment Coagulant is safe, non-toxic, non-flammable, and exhibits extremely low corrosivity. It possesses excellent hydrolytic stability and does not lose efficacy during long-term storage. Insensitive to pH fluctuations and highly resistant to chlorine, it is compatible with water treatment processes involving chlorine disinfection; it requires no separate parameter adjustments and offers high operational tolerance and adaptability.
1.3 Authoritative Compliance and Certification
This product holds NSF/ANSI Standard 60 certification for drinking water safety. Having undergone rigorous toxicological testing and impurity verification, it is a compliant polymer coagulant suitable for direct application in drinking water purification. It eliminates harmful residues and fully meets safety standards for municipal water supply and high-end water purification projects.
1.4 Multifunctional Comprehensive Treatment Capabilities
It integrates multiple functions—including charge neutralization, adsorption bridging, impurity entrapment, and water quality optimization—to simultaneously reduce turbidity, remove suspended solids, destabilize colloids, and settle organic impurities. It also enhances filtration efficiency, providing a one-stop solution for common water quality issues, with comprehensive performance far surpassing that of traditional single-component coagulants.
2.1 Standard Coagulation-Sedimentation Process
This cationic polymer coagulant is a ready-to-use liquid product that requires no complex dilution; it can be dosed directly into the rapid mixing tank of the water treatment system. High-speed agitation ensures rapid, uniform mixing with raw water, while the cationic charge neutralizes negatively charged colloids to destabilize impurities. Subsequent slow-speed flocculation agitation promotes the aggregation of micro-particles into dense, large flocs. Finally, the water enters the sedimentation tank for solid-liquid separation. The entire process is streamlined and rapid.
2.2 Specialized Direct Filtration Process
Compatible with direct filtration and contact filtration processes in water treatment plants, eliminating the need for sedimentation tanks. Upon dosing, the product rapidly alters the adsorption characteristics of the filter media, intercepting fine impurities and colloidal particles early in the process. This boosts the filter's retention capacity, effectively extending filtration cycles and increasing output efficiency. It accommodates higher flow velocities and is suitable for continuous, high-volume water purification operations.
2.3 Synergistic Application Process
Cationic Polymer Water Treatment Coagulant can be used independently as a primary coagulant, replacing inorganic agents such as PAC, aluminum sulfate, and polyferric sulfate. Alternatively, it can be used in small quantities alongside inorganic agents as a coagulant aid; this significantly reduces inorganic salt dosage, minimizes floc volume and sludge generation, and simultaneously optimizes effluent quality and the operating pressure of downstream processes.
3.1 Precise Turbidity Reduction
Targeting suspended turbidity impurities in surface water, tap water, and industrial wastewater, this product rapidly neutralizes colloidal stability and destabilizes the turbid system, causing fine, light-scattering impurities to settle quickly. Compared to traditional agents, it achieves high turbidity removal rates at low dosages; the treated water is clear and transparent, free from residual haze, and exhibits superior stability.
3.2 Thorough Capture and Removal of Fine Suspended Solids
Leveraging the adsorption-bridging effect of long-chain polymers, it captures ultrafine suspended particles that are difficult for traditional agents to handle, preventing them from penetrating filtration layers and causing effluent quality to exceed limits. It is particularly well-suited for challenging water conditions—such as low-temperature/low-turbidity water or high-turbidity water during flood seasons—ensuring stable control of suspended solids and consistent compliance with water quality standards.
3.3 Long-Term Water Quality Stability
The treated water contains no residual active colloids, eliminating issues like post-treatment re-turbidity or secondary suspension. Effluent turbidity and suspended solids levels remain stable, significantly reducing the operational load and cleaning frequency for downstream precision filtration and advanced treatment equipment, thereby saving energy and maintenance costs.
4.1 Dosage and Treatment Efficiency
Traditional inorganic coagulants (such as aluminum or iron salts) require high dosages, act slowly, and suffer from high reagent loss. In contrast, this product is a high-efficiency organic polymer; typical dosages for drinking water are only 0.2--6 mg/L (or 0.2--1 mg/L when used as a coagulant aid). Superior purification results are achieved with extremely low dosages, vastly improving reagent utilization efficiency.
4.2 Sludge Production and Disposal Costs
Inorganic coagulants generate large volumes of inorganic sludge, resulting in high solid waste disposal costs. This product effectively reduces sludge production by 15% or more; the resulting flocs are dense and have low water content, significantly lowering costs across the entire sludge management process—including transport, filter pressing, and harmless disposal—thereby offering a distinct cost-performance advantage for long-term operations.
4.3 Differences in Water Quality Adaptability and Process Compatibility
Traditional inorganic agents have narrow pH operating ranges and lack chlorine resistance, often failing in acidic/alkaline conditions or in the presence of chlorine. In contrast, this product features quaternary ammonium groups that remain stably ionized; it is insensitive to pH fluctuations and offers excellent chlorine resistance, ensuring stable operation across acidic, neutral, and alkaline water conditions without the need for frequent process parameter adjustments.
4.4 Differences in Filtration Process Performance
Traditional agents tend to form loose flocs that clog filter media, shorten filtration cycles, and reduce water output. This product optimizes the surface characteristics of filter media, resulting in longer filtration cycles, higher flow capacity, and greater water production efficiency—making it perfectly suited for the high-efficiency filtration processes used in modern water treatment plants.
4.5 Differences in Water Safety and Residual Control
Aluminum-based agents often cause secondary pollution issues, such as excessive residual aluminum and increased Total Dissolved Solids (TDS). This product is non-toxic and leaves no harmful residues; it holds NSF certification for drinking water, ensuring the treated water is free from heavy metals and harmful impurities, thereby achieving a higher level of water safety.
5.1 Municipal Drinking Water Purification
