Abstract

Compound flocculant PFS -PS is prepared with poly-ferric sulphate, silicate of natrium and sulphuricacid.Its de-emulsifying 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.

Key words： poly-ferric sulphate (PFS); polysilicate (PS); flocculant; oil/water emulsion; de-emulsifying
