For any polyaluminium chloride(PAC) manufacturer, the water purification materials for sewage treatment are widely used purification flocculants. As a relatively high-quality manufacturer, our manufacturer produces the most professional polyaluminium chloride of different specifications, which has a high cost performance and has been highly praised by new and old customers.
In the actual use process, polyaluminium chloride not only has strong coagulation and turbidity removal effect, but also has obvious decolorization and humus removal effect. It can achieve the best flocculation under the same treatment conditions. The dosage of polyaluminum chloride is as much as 2 / 3 lower than that of traditional aluminum salt. Under the same dosage conditions, polyaluminum chloride can obtain lower residual turbidity than that of traditional aluminum salt, Therefore, the same treatment results can be obtained at a lower dose.
The pH range of polyaluminium chloride is much wider than that of traditional aluminum salt. Generally, in low-temperature water, the coagulation and turbidity removal efficiency of traditional coagulants is significantly reduced, resulting in the deterioration of effluent quality. However, the use of polyaluminium chloride, whether in low-temperature or normal temperature water, can obtain better coagulation and turbidity removal effect. In addition, polyaluminium chloride can significantly improve the solid-liquid separation efficiency, Improve the performance of sedimentation filtration and sludge dewatering, so as to shorten the residence time of the sedimentation tank and increase the water production. In addition, due to the large and compact flocs, it is easy to carry out filtration and sludge dewatering. The residual aluminum content in the water after aluminum chloride treatment is very low, and the residual aluminum content in the traditional aluminum sulfate treatment water is generally 150 ~ 255 μ G / L, while the residual aluminum content in Polyaluminium treated water is only 40-55 μ g/L。
