New technology for Polyferric Sulphate(PFS) production and its application in water treatment

In order to develop a better coagulant for water treatment,this study investigates the mechanism and main difficulties in producing polyferric sulphate(PFS).Based on the investigation,the study has conducted an experiment on a new technology for PFS production and its application in water treatment.The results show that the reaction temperature increase can accelerate the reaction rate;the oxidizer usage like potassium carbonate and sodium carbonate can directly improve the oxidation.There is no pollution in water treatment after the oxidation treatment which produces potassium salts and sodium salts.The technology overcomes the key difficulties in producing polyferric sulphate and meets the performance indicators.It suits for various range of raw water,with the characteristics of less dosage,low cost and high efficiency.The study result is of significance for the development of water treatment coagulant.
