The Fava Beans were used in this work as low cost adsorbent material for removal of Pb(II), Cd(II) and Zn(II) ions from aqueous solutions. The samples were prepared without farther treatment and sorted according to the particles diameter by standard sieves 250 -500 µm. Batch adsorption experiments were carried out to study the adsorption process, several parameters such as Initial pH of adsorbent, effect of contact time, effect of adsorbent amount and effect of metal concentration were conducted in these experiments. The effects of any one of those previously mentioned parameters on the adsorption capacity were studied while the other parameters were kept constant. It was found that the obtained maximum adsorption capacities of Fave beans for the removal of selected heavy metals were very high. This provide us to use Fava beans as a low coast adsorbent material to clean up the water in the environment from toxic heavy metals such as Pb(II), Cd(II) and Zn(II) ions.

“…Therefore, the treatment of polluted industrial wastewater remains a topic of global concern. At least 20 metals are classified as toxic, in which lead and cadmium are among and many of these are emitted into the environment in quantities that pose risk to human health (Dwari et al, 2004). Adsorption has been extensively studied as an effective method for removing a wide range of hazardous materials such as heavy metals and dyes from aqueous solutions.…”

“…On the other hand, they found out that the Reynolds stress model (RSM) and the large eddy simulation (LES) model were able to provide better results in comparison with the experimental data. Ghadirian et al (2013) modeled the air core using a transient two-phase simulation, with the results of the single phase runs as the initial input data. Afterwards, they performed final simulations involving particles and found out that the use of the LES turbulence model provides the best results matched to their experimental data.…”

The velocity profiles and separation efficiency curves of a hydrocyclone were predicted by an Euler-Euler approach using a computational fluid dynamics tool ANSYS-CFX 14.5. The Euler-Euler approach is capable of considering the particle-particle interactions and is appropriate for highly laden liquid-solid mixtures. Predicted results were compared and validated with experimental results and showed a considerably good agreement. An increase in the particle cut size with increasing solid concentration of the inlet mixture flow was observed and discussed. In addition to this, the erosion on hydrocyclone walls constructed from stainless steel 410, eroded by sand particles (mainly SiO 2 ), was predicted with the Euler-Lagrange approach. In this approach, the abrasive solid particles were traced in a Lagrangian reference frame as discrete particles. The increases in the input flow velocity, solid concentration, and the particle size have increased the erosion at the upper part of the cylindrical body of the hydrocyclone, where the tangential inlet flow enters the hydrocyclone. The erosion density in the area between the cylindrical to conical body area, in comparison to other parts of the hydrocyclone, also increased considerably. Moreover, it was observed that an increase in the particle shape factor from 0.1 to 1.0 leads to a decrease of almost 70 % in the average erosion density of the hydrocyclone wall surfaces.
