The flocculation process of polyaluminum chloride

Polyaluminum chloride (PAC) is a commonly used flocculant widely used in the field of water treatment. Flocculation is a process of aggregating small particles suspended in water into larger particles for subsequent sedimentation or filtration.

Mixing and stirring: PAC is usually used in liquid form, so it needs to be mixed with water first. This is usually done in a stirring tank or reaction tank. The purpose of stirring is to ensure that PAC is fully dispersed in water in order to effectively react with suspended particles.

Forming aluminum hydroxide gel: after PAC is dissolved in water, hydrolysis reaction will occur to generate aluminum hydroxide gel. These gel particles are positively charged and can adsorb and neutralize negatively charged particles in water.

Adsorbed particles: at this time, aluminum hydroxide gel starts to adsorb suspended particles in water, including suspended soil, pollutants, etc. Since gel particles are positively charged, they will adsorb with negatively charged particles to form larger flocs.

Flocculation process: The formed flocs gradually increase, and due to their large volume and weight, they will settle or float into the water. This makes it easy for flocs to separate from water and can be removed through precipitation, filtration, or other physical treatment methods.

Sedimentation and separation: flocs settle in water, forming sludge or sediment. These sediments can be collected and separated through sedimentation tanks or sedimentation tanks. Clear water separates from the upper layer.

Polyaluminum chloride is an efficient water treatment flocculant widely used in purifying drinking water, industrial wastewater treatment, and other water treatment applications.
