polymer based flocculants review of water purification,polyacrylamide (pam) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers.
flocculation properties and kinetic investigation of sale
for water with a specific turbidity, selecting a suitable flocculant is critical to achieve high flocculation efficiency in treatment process. cationic polyacrylamide (cpam) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. this flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups. cationic monomer
chemical flocculants polyacrylamide powder,the types of flocculants, in other words industrial polyacrylamide, are cationic, anionic or nonionic polyacrylamide. kemira’s polyacrylamide of wide range of charge and molecular weight are sold in dry powder or emulsion format and have excellent performance. polyacrylamide always require specific dissolution equipment to ensure that the polymer is properly dissolved in water.
optimizing the flocculation effect of cationic polyacrylamide
cationic polyacrylamide (cpam) is a commonly used flocculant for water treatment. factors that affect the flocculation effect and can be controlled manually include the type and dosage of cpam, wastewater ph, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of cpam. in this paper, the optimal flocculation conditions of a novel cpam were
synthesis of water soluble ionic liquid copolymers flocculant,polyacrylamide and its copolymers are extensively employed in water treatment and sludge dewatering. the efficiency of flocculation is influenced by factors such as the type of flocculant used
research on a new cationic polyacrylamide (cpam) with high quality
the chemical structure and surface morphology of tpamd were characterized by various methods, mainly including ft-ir, xps, 1 h nmr, and sem. by comparing the sludge dewatering effects of template polymer tpamd, non-template polymer cpamd, and commercial flocculant cpam, the role of cationic microblock structure was evaluated.

water soluble polymer flocculants synthesis,in addition to the rate of polymer adsorption and particle collisions, the rate at which the adsorbed polymer chains relax on the particle surface (eventually forming a flattened conformation) is crucial in determining the extent of flocculation, defined by gregory as equilibrium and nonequilibrium flocculation. 9 in the latter, the adsorbed polymer is still extended when particles collide
- What are anionic polymers used for?
- Anionic polymers have a negative charge and are commonly used in applications with inorganic solids such as clays and silts. We expect to see anionic polymers used for industrial applications like sand and gravel production, drilling, mining, and other mineral-based liquid-solid separation.
- Can cationic polymers be used to treat wastewater?
- As discussed in previous sections, several researchers synthesized cationic, anionic, and amphoteric polymers to treat wastewater. Such ionic polymers mainly affect the electrokinetics, adsorption, and flocculation of the stable colloidal system in wastewater.
- How effective are polymers in water treatment?
- The polymers’ ability to flocculate solids is central to their role in water treatment. They can be effective on their own and very impactful when combined with a coagulant. Most industrial process water or wastewater includes sediment and particles with a negative electric charge.
- What is multiple/dual system in water treatment?
- Table 1. Study classification depending on the route they went in terms of water treatment. In the table, multiple/dual system besides employing multiple polymers also refers to a combination of polymer and coagulant that can charge neutralize particles individually for better polymer adherence to the particles.
