Study on pretreatment of landfill leachates using polysilicate ferrite;

In order to match the requirements of water treatment engineering, considerable attention was paid to develop composite inorganic polymer flocculants during recent years, which are represented by polyaluminum silicate chloride(PAS), polysilicate ferrite(PSF) and polysilicate ferric aluminum(PAF).

Analysis of Solid-Liquid Oxidizing Poly Silicic Ferric Sulfate(PSF-Ⅰ);

A new type of inorganic coagulant,polysilicate ferric(PSF) was prepared using sodium silicate,ferrous sulfate and sodium chlorate by a special co-polymerized method.

The phosphorus removal capability of two new-typed coagulants with silicon,which are poly-ferric silicate sulfate(PFSS)and pol-aluminum silicate chloride(PASC),has been compared under two dosing methods in three sets of batch laboratory scale apparatus for treating domestic sewage.

Study on the preparation of polyaluminum ferric silicate from coal ash;

A new type of flocculant nano-polyaluminum ferric silicate (Nano-PAFSI) was prepared by ultrasonic waves using sodium silicate, iron trichloride and aluminium chloride.

Study on preparation of polyferric silicate sulfate coagulant from iron stone and its performances

The Si species distribution of inorganic polymer flocculant polyferric silicate sulfate(PFSS)was studied by chemical Si-Mo assay.

Inorganic high polymer flocculant polyferric silicate sulfate(PFSS)with high ferric concentration was prepared by composite method with poly-ferric sulfate as direct material which conforms national standards and, in the paper is probed into the influence of mole ratio, polymerization temperature, polymerization time etc.
