Functions in Water Treatment

• Coagulation and Flocculation: In water treatment, one of the primary functions of Polydadmac is to act as a coagulant and flocculant. It can neutralize the negative charges on the surface of suspended particles in water. Many impurities in water, such as clay particles, organic matter, and some microorganisms, carry negative charges. These charged particles tend to repel each other, remaining in a stable suspension state and being difficult to settle. Polydadmac, with its positive charges, can neutralize these negative charges, reducing the electrostatic repulsion between particles. As a result, the particles can approach each other and aggregate into larger flocs, which can then be more easily removed from the water through sedimentation or filtration.
• Removal of Organic Matter: Organic matter in water can cause various problems, such as bad taste and odor, and can also react with disinfectants to form harmful by-products. Polydadmac can interact with organic matter through charge attraction and bridging effects. It can adsorb and bind organic substances, incorporating them into the flocs and removing them from the water, thereby improving the water quality and reducing the content of organic pollutants.
• Disinfection and Algae Removal: To some extent, Polydadmac also has certain disinfection and algae removal capabilities. It can disrupt the cell membranes of microorganisms and algae, affecting their normal physiological activities and reproduction, thus playing a role in inhibiting the growth of microorganisms and algae in water and reducing the microbial content in water.
• Sludge Dewatering: In the process of sewage treatment, a large amount of sludge is generated. Polydadmac is widely used in sludge dewatering. It can bind to the water in the sludge, changing the structure of the sludge and making the water in the sludge easier to separate. This significantly reduces the water content of the sludge, making it easier to handle and dispose of the sludge, reducing the volume of the sludge and the cost of subsequent treatment.

Functions in Mineral Processing

• Flotation Collector: In mineral flotation, Polydadmac can be used as a collector. For some minerals with negative surface charges, Polydadmac can adsorb on the surface of the minerals through electrostatic attraction. This changes the surface properties of the minerals, making them more hydrophobic and easier to attach to the air bubbles in the flotation pulp. As a result, the minerals can be separated from the gangue minerals and float to the surface of the pulp, facilitating their collection and separation.
• Depressant for Gangue Minerals: In some cases, Polydadmac can also be used as a depressant for gangue minerals. It can selectively adsorb on the surface of gangue minerals, increasing the hydrophilicity of the gangue minerals and making them difficult to attach to the air bubbles. In this way, the gangue minerals can be effectively suppressed, while the target minerals are allowed to float, improving the selectivity and efficiency of mineral flotation separation.
• Slurry Dispersant and Thickener: In mineral processing, the stability and fluidity of the slurry are very important. Polydadmac can adjust the properties of the slurry. As a dispersant, it can prevent the aggregation of mineral particles in the slurry, keeping the slurry in a stable dispersion state and facilitating the transportation and processing of the slurry. On the other hand, in some thickening processes, Polydadmac can also play a role in promoting the aggregation and settlement of fine particles, helping to thicken the slurry and separate the solid and liquid phases.
