With the rapid development of industrialization and urbanization, environmental problems are increasingly severe, especially the pollution and control of water resources, which have attracted extensive attention worldwide. As an important water treatment chemical, flocculant has shown its unique charm and wide application value in the field of environmental protection.


Flocculant, a chemical that causes suspended or colloidal particles in the water to aggregate with each other to form larger clumps. They can effectively remove impurities in water and improve water quality through the mechanism of electric neutralization, adsorption bridge, net sweep and so on. In the field of environmental protection, the application of flocculants is mainly reflected in the following aspects:


Flocculants play a vital role in sewage treatment. Urban sewage contains a large number of suspended matter, organic matter, heavy metal ions and other pollutants, which will cause serious damage to the ecosystem when discharged directly into the environment. By adding flocculants to the wastewater, these pollutants can be quickly aggregated into larger particles, and then separated from the water by precipitation, filtration and other processes to achieve purifying the water quality. Using Poly Aluminum Chloride (PAC) as inorganic flocculant with the organic flocculant such as Polyacrylamide (PAM) can significantly improve the flocculation effect. This combined use not only improves the efficiency of sewage treatment, but also helps to reduce the production of sludge and the cost of treatment. Besides, we can also provide other flocculants for wastewater treatment, such as Polyferric Sulphate (PFS), Aluminum Sulfate, FeCl3, PDADMAC, etc.


Meanwhile, flocculants are widely used in textile, papermaking, petrochemical and other industries. Taking the paper industry as an example, it will produce a large amount of wastewater in the papermaking process, including white water, black liquid and final wastewater, which contains many organic matter and impurities. White water is discharged by the paper machine during the paper making process, which has high fiber content and high reuse value. Using PAM for flocculation can remove the suspended matter and impurities in the water, so as to realize the recovery of white water. CPAM is a good option for treating black liquid. It can flocculate the lignin and pigment in the water, thereby removing chroma and COD. After wastewater treatment, a large amount of sludge will be produced. The use of Cationic Polyacrylamide (CPAM) can not only reduce the moisture content and the amount of the sludge, but also greatly reduce the cost of sludge treatment.


In addition, flocculants are also an indispensable part of the drinking water purification. Natural water sources often contain impurities such as sediment, algae, and bacteria, which not only affect the taste and appearance of water, but also may pose a threat to human health. Using flocculants can rapidly condense these tiny particles into larger floc, which is convenient for subsequent precipitation, filtration and disinfection treatment. It can not only effectively remove impurities in the water, but also improve the safety and taste of drinking water.


In general, the wide application of flocculants can help solve the water pollution issue and better promote ecological balance and sustainable development. If you have needs of Flocculants Used in Water Treatment, please feel free to contact us.
