A Continuous Fixed Bed Adsorption Process for Fez City Urban Wastewater Using Almond Shell Powder: Experimental and Optimization Study

This study deals with the valorization of a biomaterial, almond shell, for treatment urban effluents city Fez by fixed bed column adsorption process. A parametric analysis process is carried out conditions such as particle size, pH and height adsorbent to evaluate optimal removal percent obtain an capacity load. Characterization prior continuous was X-ray diffraction, Fourier-transform infrared spectrometry scanning electron microscopy. The seems be influenced certain parameters, size biomaterial used, pH. results suggest that this can used less expensive, available, biodegradable very effective eliminate load waters on small scale why not large replace chemicals in recover waste shell. parameters measured reached maximum values varying between 82% COD, 79% EC 71% nitrite under well-defined operating conditions, 0.063 mm, 7 cm 6.5.
