Water Soluble Polymer Flocculants: Synthesis
The flocculants are cross-linked polymers or in the form of gels. Flocculants are partially soluble flocculants (e.g., polyacrylamide-grafted amylopectin). In that case, a portion of chains is lost in the GPC pre-injection filtration system.，Polyacrylamide
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.

Polyacrylamide | Water Treatment, Soil Stabilization
polyacrylamide, an acrylic resin that has the unique property of being soluble in water. It is employed in the treatment of industrial and municipal wastewater. Polyacrylamides are produced by the polymerization of acrylamide (C 3 H 5 NO), a compound obtained by the hydration of acrylonitrile. Acrylamide is usually dissolved in water; it has,Method and Process for Municipal Sewage Treatment Using Pam The specific selection of the type of pam polyacrylamide used in municipal sewage treatment depends on the water quality of the sewage at the site and the type of sludge dewatering equipment used. Generally, experimental selection and on-site testing are conducted to determine the appropriate type and dosage of pam polyacrylamide.
Impact of polyacrylamide adsorption on flow through porous
Introduction. The flow of high molar mass polymers in porous media is particularly complex. The combination of distributed pore geometry, non-Newtonian rheological properties in confined geometry, the extensional character of the flow and the adsorption of polymer chains on the pore wall, all lead to a behavior which is difficult to predict beforehand.,Difference and application of cationic, anionic and nonionic Polyacrylamide (PAM) is a kind of linear water-soluble polymer, which is the most commonly used water treatment agent in our sewage treatment! In our practical application, PAM can be divided into cationic, anionic and non-ionic three types. How to choose these three types of PAM, we should start from the differences!
