“…The fouling experiment was carried out with 5 g/L yeast suspension to have severe fouling conditions and strong repeatability during the experiments. The yeast suspension was prepared by mixing the yeast particles with ultrapure water using a mechanical stirrer and ultrasonication for 1 h; the solution was appropriate for the performance analysis of various forms of membrane fouling 34 . All experiments were repeated three times to confirm the reproducibility of the experimental data.…”

To shed light on the effect of pulse flow on shear force and membrane fouling, the pulse frequency and flow velocity based on fiber Bragg grating (FBG) sensing technology were studied. The results show that there is a threshold for this synergy between the pulse frequency and flow velocity, which forms more easily at a high pulse frequency and low flow velocity. Moreover, the transition from pulse flow to continuous flow affects the shear force distribution with the membrane module height. Besides, at the same volumetric flow, Re gradually reaches a plateau as the pulse frequency increases from 1 to 5 Hz, and the membrane fouling control has a better flux recovery, which can reach a maximum of 28.89%. Finally, the results also show that the combined effect of high pulse frequency and low flow velocity would be higher than that of low pulse frequency and high flow velocity.

“…Based on our previous research, 29,30 yeast suspension at the concentration of 5 g L À1 was adopted as the feed water in the fouling experiment carried out at a temperature of 21.0 AE 1.0 C. This feed concentration was chosen in order to cause conspicuous fouling conditions and obtain strong repeatability during the microltration experiment. The yeast suspension was prepared by mixing the dry yeast particles with ultrapure water through mechanical stirring and ultrasonication for 30 min.…”

“…It is very well known that acrylamide is one the most widely used monomer in the preparation of hydrogel for different purposes with employing various polymerization techniques . The p(AAm) based hydrogels along with their copolymers or composites were used commonly by many researchers for various applications such as sensor, biomedical, membrane, tissue enginnering, and biological applications. Polymers which are obtained from nature are called natural or biopolymers, and have been investigated by many researchers due to their attractive properties such as renewability, biodegradability, biocompatibility, and environmental friendliness and so on .…”

Here, polyacrylamide [p(AAm)]-based hydrogels were synthesized via redox polymerization technique in the presence of various amounts of microgranular cellulose (MGCell) such as 0, 10, 25, 50, 100, and 150 mg MGCell/g. The synthesized p(AAm)-MGCell interpenetrating hydrogels were characterized spectroscopically by FTIR, thermally by TGA analysis, and mechanically via dynamic mechanical measurements. Furthermore, the effect of the amount of MGCell in p(AAm) hydrogels on swelling% (S%) degree and mechanical strength was investigated. It was found that the S% was decreased from 727 6 9 to 667 6 6, 642 6 8 and 619 6 10, 568 6 6 for p(AAm)-MGCell interpenetrating network hydrogels containing 10, 50, 100, and 150 mg MGCell, respectively. On the other hand, the Young modulus of p(AAm)-based hydrogels increased from 2.8 6 0.2 kPa to 3.1 6 0.03, 3.4 6 0.1, 3.6 6 0.3 and 4.3 6 0.3 kPa with the incorporation of 10, 50, 100, and 150 mg MGCell into p(AAm) hydrogels.
