“…Response surface methodology (RSM), an experimental strategy for find out the optimum conditions among the multivariable system is a much more efficient technique for optimization of microorganism's metabolites production (13,14). RSM is a gathering of statistical techniques for designing experiments, evaluating the effects of factors, and searching optimum conditions of factors to achieve a desirable goal (15,16). This method has been successfully applied to the optimization of medium composition, conditions of enzymatic hydrolysis, and parameters of food preservation and fermentation processes (14,17,18).…”

Optimization of draft tube position in a spouted bed reactor used for treatment of wastewater containing low concentration of heavy metals is investigated in this paper. Response surface methodology is used to optimize the draft tube height, the draft tube width and the gap between the bottom of the draft tube and the inlet nozzle. It is observed that the draft tube with a height of 60 millimeter, width of 12 millimeter and the gap of 13 millimeter between its bottom and inlet nozzle, results in optimum value of minimum spouting velocity, measured 45 cubic centimeter per second (2.7 Liter per minute).

“…However, they can be used for many purposes such as irrigation, energy production and sometimes for drinking water production, if one can properly clean it. Several methods including ultrafiltration, reverse osmosis, ion exchange, advanced oxidation processes, adsorption (KORBAHTI et al, 2007;MAHVI et al, 2005;MARTINS and MARTINS, 1993) have been developed to clean a variety of industrial wastewaters. Some of these technologies require addition of chemicals and produce large volume of sludge that requires further treatment before disposal.…”

Résumé de l'article Les rejets d'eaux usées domestiques et industrielles de la ville de Kara affectent la qualité de l'eau de la rivière Kara. Notre travail porte sur l'évaluation de la capacité du charbon actif mésoporeux préparé par activation chimique à partir de la balle de riz à éliminer la demande chimique en oxygène (DCO) et contribuer ainsi à la réduction de la pollution de la rivière de Kara. Cinq échantillons d'eaux usées prélevés sur cinq sites de la ville de Kara ont été caractérisées par le pH, la température, la conductivité, les matières en suspension (MES), la DCO, la DBO 5 et les matières oxydables (MO). Les tests de réduction de la DCO ont été réalisés par la méthode batch avec la poudre de balle de riz et deux types de charbons activés. Les effets du pH du milieu, du temps de contact, de la masse de l'adsorbant, de la valeur initiale de la DCO et la nature de l'eau usée sur la réduction de la DCO ont été évalués. Les charbons activés présentent une capacité d'atténuation de la DCO plus élevée en comparaison avec la poudre de balle de riz pour la réduction de la DCO des eaux usées. Le taux d'abattement maximal de la DCO est obtenu à 100 % pour une eau usée dont la DCO était de 1 060 mg O 2•L-1 traitée à pH 8 avec le charbon CAG-Base à la concentration en adsorbant de 10 g•L -1 pendant 60 min de contact. REMOVAL OF COD IN WASTEWATERS BY ACTIVATED CHARCOAL FROM RICE HUSK ABSTRACTThe discharge of industrial wastewater and domestic sewage from Kara city affects the quality of Kara river water. To mitigate this water pollution, the capacity of mesoporous charcoal prepared from rice husk (RH) to remove the chemical oxygen demand (COD) in wastewater samples from five sites of Kara City was investigated. The temperature, pH, conductivity, total suspended solids (TSS), biochemical oxygen demand (BOD 5 ), chemical oxygen demand (COD) and oxidizable matters (OM) of samples were analyzed. Batch experiments were applied to study the COD reduction by using powdered RH and two types of activated charcoals (AC). The experimental parameters used to identify optimal conditions for COD abatement are solution pH, contact time, mass of adsorbent and initial value of COD including the nature of wastewater. Activated charcoals showed a higher attenuation capacity of the COD in comparison with the rice husk powder. Maximal abatement rate (100%) of COD removal was obtained for the wastewater sample with a COD of 1 060 mg O 2 •L -1 trea...
