Polymeric Ferric Sulfate (PFS) Water treatment agent
1, Brief introduction
Molecular formula: [Fe2(OH)n(SO4) (3-n)/2]m, n£¼2, m£¾10, m=f(n)
Our PFS is one kind of red-brown liquid, is inorganic polymer flocculant with multi-core structure; due to its features of multi-core architecture , making it in the water purification process, both the fast and the water in the surface of colloidal particles slight negative charge to the destabilization, between the bridge or in the ion adsorption resulting from flocculation. floc generated more than a major, fast settling, flocculation effect, which has excellent cleaning ability.
