Why does the polyaluminum chloride coagulating agent not sink or float?

The coagulation treatment process of water and wastewater includes three stages: mixing and reaction of water and chemicals, and separation of flocs and water. The clarification tank is the specialized equipment to complete the above three processes. The quality of the polyaluminum chloride directly affects the treatment effect of the clarification tank water quality. Therefore, choosing a suitable water purification agent (polyaluminum chloride) is very important.

　　The medium that plays the role of intercepting and separating impurity particles in the clarifier is suspended sludge. In the clarification tank, the sedimented mud is lifted up and placed in a uniformly distributed suspended state, forming a high-concentration stable active sludge layer in the tank, the concentration of which is about 3-10g/L. The raw water flows from bottom to top in the clarifier, and the sludge layer can be in a dynamic equilibrium state in the rising water flow due to gravity. When the raw water passes through the activated sludge layer, using the principle of contact flocculation, the suspended solids in the raw water are blocked by the activated sludge slag layer and the water is clarified. The clean water is collected in the upper part of the clarifier. The rising velocity of the sludge suspension layer is related to the volume and concentration of the sludge. Therefore, the correct selection of the rising velocity and maintaining a good sludge suspension layer are the basic conditions for a better treatment effect in the clarifier.
