In situ kinetics and flocs conformation studies of kaolinite flocculated by Chi-g-CPAM | International Journal of Minerals, Metallurgy ...

The flocculation behaviour by Chi-g-CPAM can be well captured by a pseudo-first-order model. In contrast, the presence of CPAM leads to a more complex kinetics. A relatively larger fitting slope (0.4663) was obtained at the initial stage but the fitting slope droped to 0.2026 after 800 min, indicating a densification process caused by CPAM.

Water | Free Full-Text | Optimizing the Flocculation Effect of Cationic Polyacrylamide Prepared with UV-Initiated Polymerization by Response

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 ...

flocculation and reflocculation of clay suspension by different polymer systems under turbulent conditions

Flocculation and reflocculation of clay suspension by different polymer systems under turbulent conditions

For initial flocculation, the high molecular weight PEO and cationic polyacrylamide (CPAM) produced larger flocs than others. However, reflocculation of clay suspensions formed by these non- or low-charged polymers was insignificant after the initial flocs were broken under high shear force.

Ultrasonic-template technology inducing and regulating cationic microblocks in CPAM: characterization, mechanism and sludge flocculation

Contrast tests were conducted among the four flocculants (TPAD-U, CPAD, CPAM-1 and CPAM-2) to evaluated the effects of cationic microblocks on sludge flocculation performance in terms of SRF, FCMC and RT. The raw sludge had a FCMC of 96.8% and a 12 ...

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.

Water | Special Issue : Physicochemical Technology for Wastewater Treatment: Theory, Methods and Applications

A model that could guide CPAM-8.14-40.2 flocculation was obtained by RSM tests. The model optimization showed that the optimal flocculation conditions of CPAM-8.14-40.2 for treating wastewater prepared with kaolin were as follows: the CPAM dosage, wastewater pH and stirring time were 5.83 mg¡¤L ?1 , 7.28, and 5.95 min, respectively, and the turbidity of the treated wastewater was reduced to ...
