The advantages of polyaluminum chloride include:
Broad Water Quality ApplicabilityPolyaluminum chloride has a wide range of alkalinity adjustment, enabling it to achieve good treatment results for any water supply and wastewater by adjusting the alkalinity of the product or blending with various inorganic or organic compounds, especially for low-alkalinity and high-organic-pollution water quality.
Excellent Flocculation and Sedimentation EffectsPolyaluminum chloride can significantly improve solid-liquid separation efficiency, enhance sedimentation, filtration, and sludge dewatering performance, shorten retention time in sedimentation tanks, and increase water production capacity. Additionally, the large and dense flocculants formed are easy to filter and dewater.
Strong Coagulation and Turbidity Removal EffectsCompared to traditional aluminum sulfate, polyaluminum chloride exhibits strong coagulation and turbidity removal effects, achieving comparable results under the same treatment conditions. The dosage required for polyaluminum chloride is reduced by two-thirds to one time that of traditional aluminum salts, resulting in a 30-40% cost savings in treatment.
Good Decolorization and Humus Removal EffectsPolyaluminum chloride not only has strong coagulation and turbidity removal effects but also demonstrates excellent decolorization and removal of organic humus in water. Simultaneously, it significantly improves the removal of viruses, harmful, toxic organics, and bacteria.
Wide pH Application RangeThe pH application range of polyaluminum chloride is much broader than that of traditional aluminum salts. Generally, when the pH of traditional coagulants such as aluminum sulfate and ferric chloride exceeds 8.0, their treatment effectiveness decreases due to precipitation, whereas polyaluminum chloride provides good treatment results within a pH range of less than 10.
Furthermore, polyaluminum chloride features high purity, low basicity, and low iron content. These characteristics make it excel in industrial wastewater treatment, achieving good coagulation and turbidity removal even under conditions of low temperature and low turbidity water.
