Water Soluble Polymer Flocculants: Synthesis, Characterization, and

Polymer adsorption can occur through hydrogen bonding (polyacrylamide on silica silanol groups), electrostatic interaction (cationic polymers on negatively charged sludge), hydrophobic interaction (poly (vinyl alcohol) on silver iodide), and ion bridging (anionic polyacrylamide on negatively charged clays with the help of divalent calcium ion). 7

the preparation and ageing of acrylamide/acrylate copolymer flocculant

The preparation and ageing of acrylamide/acrylate copolymer flocculant

The flocculation activity achieved with aqueous solutions of polyacrylamide and acrylamide/acrylate copolymers is shown to be highly dependent upon the solution age. Continuous flocculation with a standard kaolin slurry in a Couette mixing device, giving settling rate and in-line chord length distributions, allows the comparison of different

Cationic polyacrylamide copolymers (PAMs): environmental half life

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

flocculation properties and kinetic investigation of polyacrylamide

Flocculation properties and kinetic investigation of polyacrylamide

A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.

Transfer and degradation of polyacrylamide-based flocculants in

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.

Evaluation of newly developed reverse demulsifiers and cationic

Polyamine is a highly efficient reverse demulsifier in demulsifying O/W emulsion. ? The combined PA and CPAM-2 could remove up to 90 % oil and 85 % suspended solids. ? PA-PAC exhibits comparable performance as PA and both outperform than PAC-QAS. ? Demulsification plays a more significant role than the flocculation in treating OPW. ?

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
