Synonym:Polymeric
Ferric Sulfate(PFS)
Molecular formula:[Fe2(OH)n(SO4)3-n/2]m,n<2,m>10,and
m = f (n)
Molecular weight:(400-31n)m,MG>3380
Properties:
PFS is a high-efficiency inorganic
polymeric flocculant,generally non-toxic and environmental
friendly. It is practically soluble in water,and forms
large amount of polynucleic complex ions like
[Fe2(OH)3]3+,[Fe2(OH)2]4+,[Fe8(OH)20]4+,which
are prone to render flocculation. It is advantageous as
regards the following points:its cost or quantity/effectiveness,fast settling of flocs,broad pH compatibility,low iron
contamination,high heavy metal removal rate,easy dehydration
of sludge etc.
Application:
in purification of municipal water,industrial water and waste water in varied industries
like chemical,oil,mining,paper,brewery,dye printing,steel,gas industries and more,regardless of location
and type of water source.
Generally,PFS is dissolved in
water to make an aqueous solution prior to the addition
into the water to be treated. User shall determine the
dosage according to real conditions. Once added,simply
stir to cause flocculation.
Technical Specification:
in conformity with GB14591-93 and HG/T2153-91.
