lowest cost of using poly aluminium coagulants in water treatment in china

  • Instead Alum Use Poly Aluminium Chloride ... - Water

    a) .the cost of Poly Aluminium Chloride is twice/thrice of Alum ( roughly the cost of PAC-0.4 Kg) b).One possible disadvantage in using Poly Aluminum Chloride (PAC) relates to the removal of dissolved organic carbon (DOC) from water. It is well documented that effective DOC removal is possible with alum,particularly when coagulating at lower pH values using so-called “enhanced coagulation”
