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

Research on a new cationic polyacrylamide (CPAM) with a

Flocculation is one of the commonly used sludge conditioning methods in water supply plants, which can improve the sludge dewatering performance by reducing the specific resistance of sludge (SRF), decreasing the amount of sludge, and finally lowering the transportation cost and subsequent disposal cost of sludge.

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.

Optimizing the Flocculation Effect of Cationic Polyacrylamide ... - MDPI

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

Recent Achievements in Polymer Bio-Based Flocculants for Water

The flocculation process and its effectiveness are influenced by many factors, such as the chemical structure and properties (including charge) of both the removed substance and flocculant (in the case of polymers important is also average molecular weight and its distribution), their concentration, environment pH, ionic strength, temperature, rate of mixing, and mechanism of the process [5,57

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
