Design of a Fixed-Bed Column with Vegetal Biomass and Its Recycling for Cr (VI) Treatment

The aim of this work is to design a fixed-bed column with vegetal biomass Eichhornia crassipes and the process recycling it for treatment via adsorption water loaded chromium (VI). In first stage, relationship between density microparticle calculated, giving model fixed bed. Using model, two systems Cr (VI)-contaminated were designed built. vegetable at three particle diameters 0.212 mm, 0.30 mm 0.45 was evaluated in removal (VI) from using systems, best lowest size particles allowing validation proposed Thomas model. incorporation iron into allowed near 2.0 L polluted solution, removing around 90% (VI), while only possible treat nearly 1.5 when raw biomass, 80% achieved elution EDTA, permitting reuse material more than five cycles.
