Among several separation processes, the air flotation distinguish as remarkably high potential process related to its efficiency and throughput, energy-efficient, simple process, cost-effective, applicable a wide range of oily wastewater no by-products.The current study aimed investigate effect type concentration surfactant on stability oil-water emulsion process.For this purpose, three types where used (anionic SDS, mixed nonionic Span 85/Tween 80, cationic CTAB).The results demonstrated that 80 has best stability, it increases with augmentation.The removal CTAB reached approximately 95% at 0.3%, decreased by increasing concentration.The mean diameter bubbles generated in was 71 µm, which lower than obtained other two surfactants.

Bubble motion in non-Newtonian fluids is widely present various industrial processes such as crude oil extraction, enhancement of boiling heat transfer, CO₂ sequestration and wastewater treatment. System containing liquid, opposed to Newtonian has shear-dependent viscosity, which can change the hydrodynamic characteristics bubbles, their size, deformation, instability, terminal velocity, shear rate, ultimately affect bubble rising behaviors. In this work, dynamic behavior a shear-thickened fluid studied by using an incompressible lattice Boltzmann gas-liquid two-phase flow model. The effects rheological exponent <i>n</i>, Eötvös number (<i>Eo</i>), Galilei (<i>Ga</i>) on rate are investigated. numerical results show that degree deformation increases <i>Eo</i> grows, effect <i>n</i> relates <i>Ga</i>. On other hand, velocity bubbles monotonically nonlinearly with <i>Ga</i> for given turns stronger increases. When fixed small, then decreases increase at small <i>Eo</i>, when large; but large, more uniform manner. addition, regions high rates be found near left end right bubble. size these grows <i>Ga</i>, exhibiting initial followed decrease Finally, orthogonal experimental method used obtain influences aforementioned three factors velocity. order influence arranged descending order. For greatest influence, least influence.
