Compound flocculant PFS-PS is prepared with polyferric sulphate, silicate of natrium and sulphuricacid. Its deemulsifying property to oil/water emulsion of high concentration has been studied and compared with some other coagulants. The coagulation mechanism of PFS-PS is also discussed in this paper. The experimental results show that PFS-PS is superior to the compared coagulants with its characteristics of wide adapted pH, good stability and high removal rate of oil.
