Polyaluminium chloride can be divided into two types in terms of form: solid and liquid. Solids can be divided into brown, yellow and white according to their colors. Polyaluminium chloride of different colors also has great differences in application and technology. The structure of polyaluminium chloride is composed of multi-element complexes with various forms. It has a fast flocculation and sedimentation speed and is applicable to a wide range of pH values. The floating of (PAC) flocs will affect the sewage treatment effect. The following are some measures to prevent the floating of PAC flocs:
Optimize PAC dosage and dosage method
Determine the appropriate dosage: accurately determine the optimal dosage of PAC for specific water quality through methods such as beaker test. Too little dosage will result in poor flocculation effect; too much dosage may cause the colloid to stabilize again, the flocs to become smaller and difficult to settle, and then float.
Use a reasonable dosage method: prepare PAC into a solution of appropriate concentration, and adopt a continuous and uniform dosage method to avoid local excessive dosage. At the same time, according to the water flow characteristics and mixing conditions of the reaction tank, select a suitable dosage point to ensure that PAC and sewage are fully and evenly mixed.
