Study of flocculation and modification of polyaluminum silicate sulfate;

The bleaching effluent of wheat straw pulp was treated with polyaluminum silicate sulfate (PASS).

The flocculation and coagulation of polyaluminum silicate sulfate on kaolin suspension is investigat-ed.

Study on the Aluminium Species of PASS by Using Al-Ferron Complex Timed Colorimetric Method;

STUDY ON THE PREPERATION, STRUCTURE AND PROPERTIES OF PASS;

PASS flocculant is prepared by composite copolymerization with Al 2(SO 4) 3 and Na 2SiO 3 as raw materials .

A new composite poly-ferric aluminum silica sulfate (PFASS) coagulant is prepared by using pyrite residual, calcium aluminates, water glass, and sulphuric acid as raw materials and through acidic leachig, neutralization, and polymerization.

A new type of inorganic polymer coagulant,poly-ferric aluminum silica sulfate(PFASS),was prepared by using fly ash,crap iron and waste sulfuric acid as raw materials under the conditions of reaction temperature 95—90℃,reaction time 3h,liquid solid ratio 3.

The stable polysilicate aluminium sulphate(PASS) with high aluminium content was prepared by composite method with the addition of stabilizer,using Na2SiO3·9H2O,Al2(SO4)3·18H2O as raw materials.

This paper deals with the treatment of the leach liquor of Wuhan City x Landfill Space of Refuse using poly-aluminum silicate sulfate chloride(APSSC) synthesized by changeable frequency alternating current pulse electrolysis equipment.
