  • Why is polyaluminum chloride a good coagulant for water treatment?
  • Polyaluminum chloride (PAC) is highly effective coagulant for water treatment over conventional coagulants because of low dosage requirement, shorter flocculation time, smaller amount of sludge, high efficiency and low aluminum residual in treated water .
  • What stipulations apply to polyaluminium chloride?
  • The stipulations of this Standard apply when this document has been referenced and only for polyaluminium chloride intended for use in water treatment. Polyaluminium chloride is used in the water treatment industry for the coagulation of organic and mineral colloids prior to sedimentation and/or filtration.
  • How do you coagulate a polyaluminium chloride solution?
  • It is normal to pump the solution with additional dilution water into the water being treated in order to facilitate good mixing and rapid coagulation. PolyAC refers to polyaluminium chloride.
  • How is polyaluminium chloride dosed?
  • Polyaluminium chloride is dosed as a liquid solution. It is usually dosed via diaphragm pumps into a zone of high water turbulence to facilitate rapid mixing of the solution with the water. It is normal to pump the solution with additional dilution water into the water being treated in order to facilitate good mixing and rapid coagulation.
