unraveling synergistic mechanisms of polyacrylamide,polyacrylamide (pam) is widely used as an organic polymer flocculant to improve the rheological properties of sludge and enhance its dewatering performance. however, flocculants alone are ineffective in breaking down and degrading eps to promote the release of bound water, thus they can only increase the filtration rate without significantly

polyacrylamide sewage treatment water purifier flocculation,polyacrylamide is a linear polymer chain with recurring acrylamide subunits. its formula can be expressed as (c3h5no)n, illustrating the repeating nature of its constituent monomers.the synthesis of polyacrylamide typically involves the polymerization of acrylamide (c3h5no) monomers, often through a free radical mechanism. the resulting long chains can be crosslinked to form a gel, or left linear to create a variety of forms.

application of polyacrylamide flocculants for water treatment

general patterns of water treatment with the use of polyacrylamide and its anionic and cationic derivatives have been considered in the absence and presence of mineral coagulants.

super white polyacrylamide high purity pam,polyacrylamide (abbreviated as pam or paam) is a polymer with the formula (-ch 2 chconh 2 -). it has a linear-chain structure. pam is highly water-absorbent, forming a soft gel when hydrated. in 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries.
