Coagulation and Flocculation

• Working Mechanism: Polydadmac is a kind of cationic polyelectrolyte. In water treatment, it neutralizes the negative charges on the surface of colloidal particles and suspended substances. Due to the strong electrostatic attraction, the originally repulsive particles can approach each other and aggregate. Meanwhile, the long molecular chain of polydadmac can adsorb and bridge multiple particles, gathering them into large flocs, which is conducive to the separation of solid and liquid by sedimentation or filtration.
• Advantages: It has a high positive charge density, which endows it with strong coagulation and flocculation capabilities. It can quickly and effectively remove turbidity and suspended substances in water, and has a good treatment effect in a wide range of pH values, usually from 4 to 10. Compared with some traditional inorganic coagulants, it produces less sludge, simplifies the subsequent sludge treatment process and reduces the cost of sludge disposal.
• Application Scenarios: It is widely used in the treatment of surface water for drinking water. For example, when treating water sources with high turbidity, polydadmac can quickly clarify the water and reduce the content of suspended solids and organic matter to meet the standards of drinking water. In the treatment of industrial wastewater such as papermaking and printing and dyeing wastewater, it can effectively remove a large amount of suspended substances and colloidal pollutants in the wastewater, reducing the pollutant concentration and facilitating subsequent treatment processes.

Treatment of Heavy Metal Ions

• Working Mechanism: The quaternary ammonium groups in the polydadmac molecular structure have a strong chelating effect with heavy metal ions. They can form stable complexes with heavy metal ions such as copper, nickel, lead and mercury through coordination bonds and electrostatic interactions, converting the free heavy metal ions in water into insoluble or weakly soluble forms, thus facilitating their removal from water.
• Advantages: It has a high adsorption capacity and selectivity for certain heavy metal ions, and can still work effectively in the case of complex ion coexistence. It can reduce the concentration of heavy metal ions in water to a very low level, helping to meet strict discharge standards and environmental protection requirements.
• Application Scenarios: It is often used in the treatment of industrial wastewater containing heavy metals, such as the wastewater from electroplating plants and mining enterprises. By adding polydadmac, heavy metal ions in the wastewater can be effectively removed to avoid environmental pollution caused by heavy metal emissions. In addition, it can also be used in the treatment of contaminated groundwater to purify the water quality and reduce the content of heavy metal ions.

Sludge Dewatering

• Working Mechanism: In the sludge dewatering process, polydadmac can adsorb on the surface of sludge particles, neutralize the charges on the particles, destroy the stability of the sludge colloid, and make the sludge particles agglomerate. At the same time, it can form a network structure in the sludge, which can entrap water molecules and squeeze out the bound water in the sludge under the action of external forces such as mechanical pressure, thus improving the dewatering effect of the sludge.
• Advantages: It can significantly improve the dewatering performance of sludge, reduce the moisture content of sludge, and make the sludge easier to handle and dispose of. Compared with some traditional sludge dewatering agents, polydadmac has a faster flocculation speed and a stronger dewatering effect, which can improve the efficiency of the sludge treatment process.
• Application Scenarios: It is widely used in municipal sewage treatment plants and industrial wastewater treatment plants. In the final stage of sludge treatment, polydadmac is added to the sludge to improve the dewatering efficiency and reduce the volume of sludge, which is convenient for subsequent landfill, incineration and other disposal methods.

Disinfection and Antibacterial

• Working Mechanism: Polydadmac has a certain antibacterial and disinfection effect. Its cationic groups can interact with the cell membranes of microorganisms, destroy the integrity of the cell membranes, and cause the leakage of intracellular substances, thereby inhibiting the growth and reproduction of microorganisms and achieving the purpose of disinfection and sterilization.
• Advantages: It has a broad-spectrum antibacterial effect and can effectively kill a variety of bacteria, viruses and fungi. It has good stability in water and can maintain its antibacterial activity for a long time. Moreover, it does not produce harmful by-products like some traditional disinfectants, which is more environmentally friendly.
• Application Scenarios: It can be used in the disinfection of swimming pool water to keep the water clean and hygienic and prevent the growth of bacteria and algae. In some water treatment systems that require antibacterial and disinfection treatment, such as the circulating water system of air conditioning and the water supply system of buildings, polydadmac can be used to control the growth of microorganisms and ensure the water quality safety.
