polyacrylamide in wastewater treatment applications
in municipal wastewater treatment, polyacrylamide plays several key roles: (1) flocculation: pam can bind with suspended solids in the wastewater, forming larger flocs to achieve solid-liquid separation. this helps to improve sedimentation rates and reduce the burden on subsequent treatment equipment. (2) purification: pam can effectively

recent achievements in polymer bio-based flocculants for sale,an example is work by zhou and framks,where three cationic polymers (homopolymer of diallyldimehylammonium chloride and its two copolymers with acrylamide) of different molecular weights (1.1–3.0 × 10 5 g/mol) and charge density (cd) (10%, 40%, and 100%) were used as flocculants for silica aggregates. they conducted experiments in
- What is polyacrylamide polymer?
- Polyacrylamide, also briefly referred as PAM, is commonly a polymer with acrylamide monomers bonded connected by end to end configuration; it is a hard glassy solid at room temperature. Because of the difference in production methods, the products can be white powder, translucent beads and flaky like.
- What is polyacrylamide used for?
- Polyacrylamide has effects of flocculation, thickening, drag reduction, adhesive, colloidal stabilizing, filming and preventing scale. It is widely used in papermaking, mining, coal washing, metallurgy, oil exploitation and other industrial sectors and is also a important chemical for water treatment. Figure 1 The synthetic route of polyacrylamide.
- Is polyacrylamide soluble in water?
- Polyacrylamide is insoluble in benzene, toluene, xylene, gasoline, kerosene, diesel fuel, but soluble in water. Polyacrylamide can react with alkaline with partial hydrolysis of polyacrylamide. It will have imidization reaction in strongly acidic (pH≤2.5) which will reduce its solubility in water.
- Do pressure-driven flows of high molecular weight polyacrylamide solutions decrease?
- Pressure-driven flows of high molecular weight polyacrylamide solutions are examined in nanoslits using fluorescence photobleaching. The effective viscosity of polymer solutions decreases when the channel height decreases below the micron scale. In addition, the apparent slippage of the solutions is
