An advanced treatment process for 3-high wastewater discharged from crude oil storage tanks

Recent advances in functional micro/nanomaterials for removal of crude oil via thermal effects

“…[11][12][13] For oil spills in aqueous environments, the most commonly used oil-water separation methods can be divided into three major classes: biological treatment, chemical treatment and physical/mechanical treatment. 14,15 Specifically, examples include bio-oxidation separation, enzyme treatment; [16][17][18][19][20] coagulant treatment, 21,22 electrical separation, 23 in situ combustion; 24,25 gravity separation, [26][27][28] skimmers, 29,30 filtration separation, 31 centrifugal separation, 32 adsorption separation and so on. However, chemical methods and biological methods can also cause secondary pollution and have high requirements for water intake, professional maintenance, and high infrastructure costs.…”
