Publish Time: 2025-03-21
As an efficient, economical and environmentally friendly water treatment agent, polyaluminium chloride is highly respected for its excellent stability, wide applicable water area, rapid hydrolysis rate and strong adsorption capacity. From domestic water to industrial wastewater, polyaluminium chloride has demonstrated excellent water purification effects in many fields.1. Domestic water treatmentIn the treatment of domestic water, polyaluminium chloride plays a vital role. It can effectively remove suspended matter, colloids, organic matter and some heavy metal ions in water, and improve the transparency and taste of water. At the same time, polyaluminium chloride can also remove odor and color in water through its strong adsorption capacity and electrical neutralization, making the treated water clearer and purer.In addition, when treating domestic water, polyaluminium chloride can also effectively remove bacteria and viruses in water to ensure people's drinking water safety. Its efficient sterilization and deodorization capabilities make the treated water more in line with people's drinking needs.2. Industrial wastewater treatmentIn the field of industrial wastewater treatment, polyaluminium chloride also demonstrates a strong water purification ability. It can be used to treat various industrial wastewaters, such as printing and dyeing wastewater, leather wastewater, fluoride-containing wastewater, heavy metal wastewater, etc. Through the flocculation and precipitation of polyaluminium chloride, pollutants such as suspended matter, colloids, organic matter and heavy metal ions in these wastewaters can be effectively removed, thereby achieving the purpose of purifying water quality.Especially when treating printing and dyeing wastewater and leather wastewater, the decolorization effect of polyaluminium chloride is particularly significant. It can quickly condense the pigment molecules in the wastewater into larger particles, and remove them through precipitation, so that the wastewater becomes clear again.3. Other application fieldsIn addition to domestic water and industrial wastewater treatment, polyaluminium chloride is also widely used in other fields. For example, in the papermaking industry, polyaluminium chloride can be used as a sizing agent and retention agent to improve the quality and output of paper; in the textile printing and dyeing industry, it can be used as an anti-wrinkle agent to improve the feel and appearance of fabrics; in the pharmaceutical and cosmetics industries, polyaluminium chloride can be used as a raw material or additive to produce various medicines and cosmetics.In addition, polyaluminium chloride can also be used in soil improvement, aquaculture and other fields. In soil improvement, it can increase the moisture content and air permeability of the soil and promote plant growth; in aquaculture, it can effectively remove organic matter and suspended matter in the water, providing a good growth environment for aquatic organisms.4. Water purification mechanism of polyaluminium chlorideThe reason why polyaluminium chloride can show excellent water purification effects in many fields is mainly due to its unique water purification mechanism. It uses a variety of mechanisms, including compression double layer, adsorption and electrical neutralization, adsorption bridging and sediment capture, to cause the fine suspended particles and colloidal ions in the water to lose stability, and then achieve aggregation, flocculation, coagulation and precipitation, so as to achieve the purpose of purifying water quality.In summary, polyaluminium chloride, as an efficient, economical and environmentally friendly water treatment agent, has demonstrated excellent water purification effects in domestic water, industrial wastewater and many other fields. Its unique water purification mechanism and wide application fields make it an important member in the current water treatment field.
