For (Al-Fe)nof 9% with a dosage of 0.8% or (AlCl3)nof 10 g/L with a dosage of 3%,the wastewater COD removalcan reach more than 36%.
Considering the cost and dosage, (Al-Fe)n of 9% with a dosage of 0.8% is the best and is selected.
(Al-Fe)n of 9% (m/m) was confirmed as a good coagulant and had the best removal effect at a dosage of 0.8% (v/v).

Al disks were coated by harder Ni particles, while a Zr-Ti powder blend was deposited onto Cu targets.
The gradual decrease of the fcc Al-peaks refers to the development of a more uniform coating layer.
It should be noted that the Al-peaks decrease during the first 20 min of milling, while sharper Al-peaks re-appear after 30 min.
When Al disks are coated by harder Ni particles, intermetallic phases develop by a solid state reaction.

From early 1970s technical journals, symposiums and conferences considering the use of surfactant for enhanced oil recovery includes Halbert and Inks, 1971 [10], Holm, 1971 [11]; Healy et al.,1975 [12]; Dreher and Sydansk, 1976 [13]; Healy and Reed, 1977 [14]; Nelson and Pope, 1978 [15]; Glover et al., 1979 [16]; Meyers and Salter, 1980 [17]; Puerto and Reed, 1983 [18]; Bouabboune et al., 2006 [19].
Feng et al result concluded that the optimal surfactant concentration for that oil field is 2% with an additional oil recovery of 0.22%.
Abhijit et al in (2011) [25], established in their study that the surface tension of surfactant increases in the presence of polymer.
