water soluble polymer flocculants: synthesis

Water Soluble Polymer Flocculants: Synthesis

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

Targeting nanoplastic and microplastic removal in treated

Such results were expected because polyacrylamide flocculant is known to form shear-resistant flocs, which limits the effect of increasing velocity gradients on the correlation 15.

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.

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

Polyacrylamide, as an organic polymer flocculant, was widely used in the flocculation treatment of mineral processing wastewater and tailings. In this paper, the types of polyacrylamide commonly used in flocculation of wastewater generated from the beneficiation of metal ore, oil sand and phosphate ore were summarized. 1. Introduction

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.

The Use of Polymers in the Flotation Treatment of Wastewater

four different polymers were tested. Ferric sulphate at 30 mg/L plus 3 mg/L of an anionic polyacrylamide gave the best performance, with 87% removal of oil and grease [26]. The aim of another recent study was to assess the effect of alum and cationic polyelectrolytes on the removal by DAF of hydrocarbons from petrochemical wastewater [22].
