  • What is poly Aluminium chloride process?
  • Poly Aluminium Chloride process has been fine tuned by Contec during these years. Contec selected process condition in order to obtain the maximization of most active oligomeric forms of PAC which are the most susceptible to give rise to high cationic poly-nuclear hydroxyl-aluminium complexes.
  • What are the synthesis parameters of aluminum chloride hexahydrate?
  • The synthesis parameters were concentration of aluminum chloride hexahydrate (0.4 to 0.8 M), basicity ratio (2.0 to 2.4), reaction temperature (60 to 80 °C) and time (180 to 360 min). The performance of PΑC for water treatment was also investigated. The monomeric, medium polymeric and colloidal species of PAC were determined by Ferron test method.
  • How is polyaluminum chloride produced?
  • Polyaluminum chloride (PACl) is a typical inorganic coagulant and generally produced by two steps including acid-dissolution of aluminum hydroxide and adding base to aluminum chloride until an empirical formula of Al (OH)nCl3-n (with n from 1.0 to 2.5) is achieved (Shen and Dempsey., 1998).
  • How does Contec produce polyaluminum chloride coagulants?
  • Contec produces a wide range of polyaluminum chlorides diversified by the value of the basicity and the aluminium content. The process can be divided in two steps: The reaction Where we can produce, in the glass line reactor, polyaluminum chloride coagulants with a low and medium basicity.
