polyacrylamide degradation and its implications

Polyacrylamide degradation and its implications

High molecular weight (10 6 ¨C3 ¡Á 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and...

Cationic polyacrylamide copolymers (PAMs): environmental half

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.

research on a new cationic polyacrylamide (cpam)

Research on a new cationic polyacrylamide (CPAM)

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

Recent Achievements in Polymer Bio-Based Flocculants

The comparison of the flocculation results of the compounds tested with the commercial polyacrylamide flocculants shows their great suitability for water treatment. An amphoteric flocculant was obtained by grafting of methacryloxyethyltrimethyl ammonium chloride (DMC) and acrylic acid (AA) copolymer onto microcrystalline cellulose [ 104 ].

Comparative study on the effectiveness of hydrophobically

Research Highlights Polyacrylamide has been modified with cationic hydrophobic groups: AHPTHAC, AHPTOAC and AHPTDAC. Charge densities and molecular weights varied with the addition of different concentration of the hydrophobic group. Molecular weight and change density have an inverse relationship. The bridging mechanism was the dominant mechanism in flocculating kaolin suspension.

In this study, a novel amphiphilic flocculant TP-ADL was synthesized using acrylamide, methacryloxyethyltrimethyl ammonium chloride and lauryl acrylate as monomers through UV-light-initiating template copolymerization technology. Copolymerization conditions were optimized towards higher intrinsic viscosity and conversion rate. The Fourier transform infrared spectroscopy and 1H nuclear magnetic
