The present investigation is a follow-up of study on manufacturing Raschig ring for removal of lead from aqueous solution. The mixtures were formulated using cement kiln dust, zeolite, and bentonite, normally used as natural adsorbents in the industrial scale, according to mixture design algorithm and response surface method. The pastes were prepared by(More)
To close the system of equations, different turbulence models have been used. These include: − ε k , −ω k and Reynolds Stress models. On the inlet boundary, the concentration and velocity distribution are known. The saline current enters the channel, under the quiescent pure water, with a uniform concentration and velocity. On the surface of the bed, the(More)
