“…Hence, both mono and multilayer adsorptions occur in the present studies with preference to monolayer adsorption. A similar observation on data confirmation to combination of mechanisms -Freundlich and Langmuir isotherms was reported in reduction of COD in sugar industrial effluent (Parande et al, 2009) and removal of dyes (Ho and McKay et al, 2003). …”

“…5). Similar optimum pH at 7 and a fall in removal capacity afterwards was observed in the removal of COD from wastewater of coffee processing plant (Rani Rani Devi, 2010) and sugar industrial effluent (Parande et al, 2009). However, a slight enhancement in COD adsorption for pH values ranging from 7.5 to 8 was observed (Muftah H. ElNaas et al, 2010) whereas, maximum COD removal was observed at pH 3.0-4.5 and 5.5 -7.0 using activated coconut shell and industrial grade granular activated carbon respectively (Mahesh et al, 1999).…”

“…Among all the reported methods, biosorption is considered as a most promising technique because it is rapid, economic and environmentally benign technology and also is not associated with the generation of secondary wastes which present treatment problems (Verma and Mishra, 2010;Ramesh et al, 2014). In several previous reports, many investigators have studied the use of various plant materials as adsorbents for the reduction of COD from waste water, such as, avocado peel or seed carbon Rani Devi, 2010), metakolin, dates nut carbon and tamarind nut carbon (Parande et al, 2009). Hence, in this study an attempt is made to develop low-cost, effective and commercially applicable adsorbents from agricultural wastes (casuarina fruit, sorghum stem and banana) and to study their usage for minimizing the COD levels from coffee waste water to cater the needs of developing and underdeveloped countries.…”

The utilization of three novel and distinct agricultural waste materials, namely casuarina fruit powder (CFP), sorghum stem powder (SSP) and banana stem powder (BSP) as low cost adsorbents for reducing chemical oxygen demand (COD) levels of coffee industry wastewater has been examined. Prepared adsorbents were characterized by scanning electron microscopy (SEM), Energy-dispersive x-ray spectroscopic (EDAX) and Fourier Transform Infrared Spectroscopy. The effects of parameters like adsorbent dose, pH, temperature, agitation rate and time of adsorption on the reduction of COD levels were analyzed for each adsorbent individually and the efficiency order is CFP>SSP>BSP. Based on the extent of compatibility to Freundlich/Langmuir adsorption isotherm and different models (pseudo-first order and second order, Boyd, Weber's and Elovich), simultaneous occurrence of chemisorption and physisorption was proposed. Based on the observations, it is proposed that three kinetic stages involve in adsorption process viz., diffusion of sorbate to sorbent, intra particle diffusion and then establishment of equilibrium. As these three adsorbents exhibit adsorption capacity more than 80%, the adsorbents prepared from agricultural wastes have promising role towards reduction of COD from industrial wastewater to contribute environmental protection.

“…A wide variety of activated carbon derived products is available, exhibiting markedly different characteristics depending on the raw material and activation technique. It is usually prepared from coal, coconut shells, lignite, wood chips, sawdust, paddy husk, among others, and it can be prepared using one of the two basic activation methods: physical and chemical [68][69][70][71][72][73][74][75][76]. Generally, the physical activation requires high temperature and longer activation time when compared to chemical activation.…”

As the current global trend towards more stringent environmental standards, technical applicability and cost-effectiveness became key factors in the selection of adsorbents for water and wastewater treatment. Recently, various low-cost adsorbents derived from agricultural waste, industrial by-products or natural materials, have been intensively investigated. In this respect, the eggshells from egg-breaking operations constitute significant waste disposal problems for the food industry, so the development of value-added by-products from this waste is to be welcomed. The egg processing industry is very competitive, with low profit margins due to global competition and cheap imports. Additionally, the costs associated with the egg shell disposal (mainly on landfill sites) are significant, and expected to continue increasing as landfill taxes increase. The aim of the present review is to provide an overview on the development of low-cost adsorbents derived from eggshell by-products.

“…Organic pollutants are from source such as domestic waste that incorporates domestic, industrial and municipal wastewater. Removal of organic pollutants and heavy metals by adsorption has been widely used for wastewater treatment (DEVI and DAHIYA, 2010;PARANDE et al, 2009). Industrial wastewater often contain appreciable concentrations of biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids, highly toxic compounds and dyes (ABOULHASSAN et al, 2006;AKYOL, 2012;MALAKOOTIAN et al, 2008).…”

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...
