  • 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.
  • 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.
  • Can polyaluminium chloride improve coagulation process in conventional water treatment?
  • The coagulation process in conventional water treatment could be enhanced and the ensuing water pH decline reduced appreciably by applying the right dosage of polyaluminium chloride and appropriate process conditions of pH, fluid mixing speed matrix and residence time.
