“…Some of them pointed out the use of tannins as a coagulant aid [20] or other cationic compounds [21]. Specifically, the use of tannin-based coagulants was researched only by Graham et al [22], as well as by us [23][24][25].…”

“…Samples of lean sludge were collected from the "El Khanka" Water Treatment plant in Egypt. Cationic polyacrylamide was used as a coagulant with bentonite to test its combination effect as the cationic polymer did not change the pH of the water and was found to be more comfortable in handling as per Polasek and Mutl [16].In this study, the focus was given to using cheap natural adsorbents to remove Aluminium ions from lean sludge.…”

Aluminium ions traces in drinking water were found in El Khanka Water Treatment plant in Egypt because of the lean sludge generated from Alum’s use in water treatment. This research studies using natural clay such as “bentonite” known as montmorillonite clay and combining bentonite – cationic polymer as coagulants to remove aluminium salts from lean sludge. Experimental studies were performed to determine the effect of adding bentonite on the removal of aluminium ions from lean sludge based on variation of pH. 98.8% removal of Al ions was achieved at pH 11, and 0.6 ppm concentration of bentonite in the sludge solution. Kinetic model of pseudo-second-order was found to be the best to describe the reaction and the rate constant of 11.922 mol.-1 s-1 was calculated. An industrial process was suggested to the removal of Aluminium ions and brief economic estimate of applying it in Egypt was prepared as well.

Fe3O4-armored latexes were successfully synthesized by using modified Fe3O4 (IO) nanoparticles as stabilizers without a surfactant. The particle size, conversion, and particle number density of latex particles during the formation process were studied in detail. The surface charge density and the particle size evolutions of latexes were studied by dynamic light scattering. The use of scanning electron microscopy confirmed that IO nanoparticles were adsorbed on the polymer particle surface. Furthermore, the efficiency of iron oxide incorporation (IE) was evaluated by thermogravimetric analysis. The effect of pH, solid content, and zeta potential of IO nanoparticles on the results of polymerization was also discussed in detail. Attempts were made to explain the change of latex particle surface charge density by using Guy-Chapman-Stern’s electric double layer theory. In addition, the effect of ionic strength of ammonium sulfate on particle number density of latex particles was described using P. John Feeney’s equation. Finally, the mechanistic insights were discussed by studying polymerization kinetics.
