摘要: This paper is concerned with the performance of a relatively new form Fe(III) coagulant, Polyferric Sulphate (PFS), which contains range pre-formed hydrolysis species both high positive charge and medium large molecular weights. Preliminary laboratory pilot-plant experiments were undertaken to evaluate PFS, in comparison conventional coagulants such as ferric sulphate (FS), for coagulation surface waters containing substantial concentrations algae and/or colour, natural organic matter.
