improvement of alum and pacl coagulation by polyacrylamides

Improvement of alum and PACl coagulation by polyacrylamides

A combination of inorganic coagulant and flocculant or polymer is applied in which alum and PACl are used coupled with the C-PAM (Organopol 5415) and A-PAM (Chemfloc 430A). Overall, alum coupled with Organopol 5415 is the best system among all systems studied.

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]

penetration control of surface sizing starch using cationic

Penetration control of surface sizing starch using cationic

This study was focused on the use of cationic polyacrylamide (PAM) as a surface sizing additive to control the penetration of starch solutions into paper, thus improving bending stiffness of paper. The effects of the ionic property, viscosity, and charge density of PAM on starch penetration and bending stiffness of surface sized papers were ...

The flocculation performance of polydiallydimethylammonium chloride (polyDADMAC) coupled with polyacrylamide for treating pulp and paper mill wastewaters was studied. The flocculation performance tests were carried out in jars with polyDADMAC and polyacrylamide (PAM) dosages of 0.4¨C2.0 mg L ?1 and 0.4¨C8.0 mg L ?1, respectively

The negatively charged particles started to aggregate with the addition of C-PAM, and the floc size was measured every 30 s for 10 min after the C-PAM addition, giving a total of 20 measurements. Although temperature is a major factor affecting flocculation, most studies on particle aggregation have been conducted at room temperature (Fuente et ...

PAM was used to improve the speed of solid-liquid separation, so that the particles settled quickly and the supernatant became clear. It was obviously that the selection of appropriate PAM products played a very important role in the effective solid-liquid separation to reduce the operation cost. 2. Type of Polyacrylamide 2.1. Anionic PAM
