Cationic polyacrylamide copolymers (PAMs): environmental half

Background Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land. Concern has been expressed since little is known about the degradation of PAMs in soils. To obtain detailed information on the polymer¡¯s fate in the soil compartment, the degradation of 14C

polyacrylamide soil conditioners: the impact on

Polyacrylamide Soil Conditioners: The Impact on

Polyacrylamides (PAMs) are group of water-soluble, synthetic polyelectrolytes derived from acrylamide monomer in polymerization process [ 1, 2, 3 ]. They are substances which dissolve, disperse, or swell in water and thus can modify physical properties of aqueous system due to thickening, gelation, emulsification, or stabilization processes.

water soluble polymer flocculants: synthesis

Water Soluble Polymer Flocculants: Synthesis

Flocculants with less than 1% charged functional groups are considered as nonionic flocculants. 34 Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. 35 Polyacrylamide is the most important water soluble nonionic flocculant because its monomer, acrylamide

optimizing the flocculation effect of cationic polyacrylamide

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

Transfer and degradation of polyacrylamide-based flocculants

Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain residual monomer of acrylamide (AMD), which is known to be a toxic compound.
