through the hydrogel, while the oleophobicity prevents oil from entering or passing through the hydrogel. In this research article, we use polyacrylamide (PAM) based hydrogels to achieve the objective of separating oil from oil/water mixture. A major benefit of using PAM based reinforced membrane is that the fouling of the hydrogel by the oil is .

Hence, in order to obtain membranes which separate oil¨Cwater mixtures and filter water while retaining oil on its surface, the PAM coating is required (second stage). This is illustrated in Fig. 5 , where the critical intrusion pressure, P c (see Section 2.7 ) is plotted as function of the number of coating cycles, N ( P c = 0 for N = 0 in ...

polyacrylamide - wikipedia

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]

In this study, the in?uence of various factors on the synthesis of stable polyacrylamide microemulsions was discussed, and the instability and turbidity of the products prepared by traditional emulsions were overcome. At the same time, polyacrylamide (PAM) was prepared by a new method of inverse microemulsion polymerization with (NH4)2S2O8-

The results indicate there is a degree of compromise between three factors that are related to the amount of PAM coating: avoiding biofouling (which can block the flow, induce corrosion, etc.), maintaining an important flow of water and sustaining a given intrusion pressure of oil on the membranes.

Isolation and Characterization of Polyacrylamide-Degrading

Polyacrylamide (PAM) is a water-soluble polymer that is usually produced through the polymerization of acrylamide with one or more copolymers. The amide groups of PAM form hydrogen bonds in aqueous solutions, and high-molecular-weight PAM is an effective flocculant of suspended solids in water via charge neutralization and interparticle ...
