For many years, polyaluminum chloride has developed into a flocculant with mature technology and large market sales, and it has gradually replaced conventional flocculants. Western European countries began production of polyaluminum chloride in 1976 as an industrial wastewater treatment flocculant; the United States and Canada approved it in 1983 for urban water supply and industrial wastewater treatment. Polyaluminum chloride is a commonly used agent for water treatment of coagulants. The effect of water treatment is significant, and it plays a crucial role in the purification of drinking water and industrial wastewater. The commonly used polyaluminum chloride content is: 26%, 28%, 30%. The content of polyaluminum chloride varies depending on the application, and the corresponding price of polyaluminum chloride is also different.
The polyaluminum chloride has the advantages of good spray drying stability, wide adaptability to water, rapid hydrolysis, strong adsorption capacity, large bloom formation, fast density sedimentation, low effluent turbidity, good dewatering performance, etc., under the same water quality conditions. The spray dried polyaluminum chloride dosage is reduced. Especially when the water quality is not good, the spray drying product dosage can be reduced by half compared with the roller drying polyaluminum chloride, which not only reduces the labor intensity of workers, but also It is important to reduce the user's water costs. In addition, spray drying products can ensure safety, reduce water accidents, and are very safe and reliable for residents' drinking water.
Polyaluminum Chloride The content of polyaluminum chloride is also different for different uses. The user can choose the corresponding polyaluminum chloride according to their different uses. The following is a summary of the use of Gongyi Xinrui water purification on different levels of polyaluminum chloride.
1. Polyaluminum chloride with an AL2O3 content of more than 30%. Suitable for drinking water industry. Specific industries include: water purification plants, pure water plants, pharmaceutical plants, food processing plants and other industries with relatively high water quality requirements.
2. Polyaluminum chloride with an AL2O3 content of 28% is suitable for industrial wastewater treatment. Specific industries include oily wastewater, printing and dyeing plants, papermaking wastewater, steel plant wastewater, coal washing plants, and plastics plants with high turbidity and water quality.
3. Polyaluminum chloride with an AL2O3 content of 26% and below 26% is suitable for the treatment of urban domestic sewage. This level of polyaluminum chloride is suitable for the treatment of low turbidity municipal sewage.
Polyaluminum chloride price: normal price is based on its content, 30%, 28% prices are not the same, 30% is divided into spray drying and frame filter press type and drum drying type, polyaluminum chloride price The higher the best spray drying type, the color appearance is light yellow powder; the 28% content of polyaluminum chloride is slightly cheaper, and the commonly used treatment water is industrial sewage treatment.
