The role of coagulants

In the water treatment process, coagulants (such as polyaluminum chloride, aluminum sulfate, etc.) are key chemical agents used to remove suspended solids and colloidal impurities from water. Its working principle is to use charge neutralization and adsorption bridging to aggregate small particles into larger flocs (alum flowers), which facilitate subsequent precipitation or filtration removal.

Application scenarios:
Waterworks: purify raw water with high turbidity.
Wastewater treatment: Pre treat industrial wastewater or domestic sewage.
Pool maintenance: Keep the water clear.
