Polyaluminium chloride: role in sewage treatment
As a new water purification material, polyaluminum chloride has a high degree of neutralization and bridging effects on colloids and particles in water, and can strongly remove micro-toxic substances and heavy metal ions,Polyaluminum chloride manufacturersThe produced polyaluminium chloride is an inorganic polymer water treatment agent with large relative molecular mass and high charge.
After years of research,Polyaluminum chloride manufacturersThe production technology should be more mature at present, and the sales volume of such products in the market also accounts for a large proportion. A large number of application practices show that the use of polyaluminum chloride instead of traditional iron and aluminum salt coagulants in water treatment can significantly improve the water purification effect, reduce the amount of use, reduce the cost of treatment, and improve the quality of effluent water. Compared with other water purification materials, it has absolute advantages. For example, in the process of purifying water, the addition of polyaluminum chloride has a wider range of pH than traditional aluminum salts. In general, the regular coagulants aluminum sulfate and ferric chloride salts form aluminum hydroxide precipitates at pH> 8.0, thereby reducing the effectiveness of their treatment, and better results will be obtained in the range.
Compared with the traditional aluminum sulfate and ferric chloride,Polyaluminum chloride manufacturersThe product has stronger agglomeration and turbidity. Under the same treatment conditions, the cost can be saved by 30-40%; under the same dosage conditions, polyaluminum chloride is used to obtain a lower residual turbidity than regular aluminum salt, thereby obtaining a better lower dosage treatment effect.
Polyaluminum chloride also has a good decolorization effect and can effectively remove organic humus in water, at the same time, harmful, toxic organic matter and pathogen removal has also been significantly improved. In addition, becausePolyaluminum chloride manufacturersWith a wide range of alkalinity adjustment, alkalization can be adjusted from 40% to 90% strong coordination, suitable for any wastewater. By adjusting the alkalinity of the product or the formulation of various inorganic or organic compounds, a better treatment effect can be achieved, especially for low alkalinity and high organic pollution water.
