Polyacrylamide - Wikipedia

Polyacrylamide (abbreviated as PAM or pAAM) is a polymer with the formula (-CH 2 CHCONH 2 -). It has a linear-chain structure. PAM is highly water-absorbent, forming a soft gel when hydrated. In 2008, an estimated 750,000,000 kg were produced, mainly for water treatment and the paper and mineral industries. [1] Physicochemical properties [ edit]

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.

Polyacrylamide (PAM) is widely used in polymer flooding processes to increase oil recovery while the byproduct of PAM-containing wastewater is a serious environmental issue. In this study, electrochemical oxidation process (EAOP) was applied for treating PAM wastewater using a new type of 3-dimensional ultra-thin SnO 2 -Sb electrode.

Second, mechanical degradation was compared to chemical degradation of PAM under HVHF chemical conditions (high temperature, mg L ?1 level Fe 2+ at pH < 4) in terms of MW distribution and chemical functional groups of degraded polymer. Furthermore, sequential and combined degradation experiments by the two mechanisms were performed and the
