  • What is polyaluminium chloride production?
  • PolyAluminium Chloride production is one of the most exigent process for glass-lined equipement due to its high corrosive and abrasive effect. That's why, the experience and the qualification of De Dietrich Process Systems allow to meet qualitatively those process requirements.
  • 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.
  • Is polyaluminum chloride used in water treatment?
  • Polyaluminum chloride (PAC) can be synthesized and used in water treatment as investigated in this study using a colorimetric speciation method. Stable preparations of PAC solutions can be produced where a relatively stable cationic polymer predominates.
  • Which coagulants are used in water purification?
  • Among them, polyaluminium chloride is the most widely used in water purification due to its fast flocculation speed and large floc size [ 1, 2, 3, 4, 5, 6, 7 ]. In water treatment plants, in order to improve the efficiency of coagulation process, the use of prehydrolysed coagulants in place of aluminium sulphate (VI) is a common practice.
