Polyacrylamide PAM Flocculant for Water Treatment

Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.

polyacrylamide

Polyacrylamide

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]

degradation of polyacrylamide (pam) and methane production by mesophilic and thermophilic anaerobic digestion: effect of temperature

Degradation of Polyacrylamide (PAM) and methane production by mesophilic and thermophilic anaerobic digestion: Effect of temperature

Polyacrylamide (PAM) is generally employed in wastewater treatment processes such as sludge dewatering and therefore exists in the sludge. Furthermore, it degrades slowly and can deteriorate methane yield during anaerobic digestion (AD). The impact or fate of PAM in AD under thermophilic conditions is still unclear. This study mainly focuses on PAM degradation and enhanced methane production

Research on a new cationic polyacrylamide (CPAM) with a cationic microblock structure and its enhanced effect on sludge condition and

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. Therefore, it is particularly important to develop new and efficient flocculants

Chapter 8 POLYACRYLAMIDES WE1 S. YEN, ANTHONY T. COSCIA and SAMUEL I. KOHEN INTRODUCTION Among the various polymers that have been studied for chemical enhanced oil recovery (see Chapter 7), polyacrylamide (PAM) is the most important. PAM is used frequently for mobility control as well as permeability control.
