Hydrothermal pretreatment of sewage sludge enhanced the anaerobic degradation of cationic polyacrylamide (cPAM)

Cationic polyacrylamide (cPAM) is a widely used flocculant to dewater sewage sludge (SS) for high-solids anaerobic digestion (AD), and its degradation is crucial since it would release toxic acrylamide (AM) once entering environment. Hydrothermal treatment (HTT) is an efficient method to enhance the AD efficiency of SS.

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

Cationic polyacrylamide copolymers (PAMs): environmental half life determination in sludge-treated soil | Environmental Sciences Europe

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

Application of FeCl3 to Adjust Urban Sewage-Dewatered Sludge (UDSS) Containing Cationic Polyacrylamide (CPAM) for Further Dewatering | Water, Air

At present, cationic polyacrylamide (CPAM) are the most widely used conditioners in most wastewater treatment plants, owing to its strong bridging function. Although the dewaterability of USS can be improved by CPAM, the moisture contents of urban sewage-dewatered sludge (UDSS) are still above 75% which corresponds to the high compressibility of the sludge.

Understanding the synergistic mechanism of PAM-FeCl3 for improved sludge dewaterability

Among various chemical conditioners, cationic polyacrylamide (CPAM) is widely used in sludge treatment plants due to its advantages of fast treatment rate and wide application range. However, the disadvantages of CPAM for sludge dewatering are its high filter cake moisture content (FCMC) and slow filtration rate.
