Oily Wastewater Treatment Using Expanded Beds of Activated Carbon and Zeolite
Two types of adsorbents were used to treat oily wastewater, activated carbon and zeolite. The removal efficiencies of these materials were compared to each other. The results showed that activated carbon performed some better properties in removal of oil. The experimental methods which were employed in this investigation included batch and column studies. The former was used to evaluate the rat...
متن کاملBiosorption of Cr (VI) using a bacterial biofilm supported on granular activated carbon and on zeolite.
Two mini-columns partially filled with granular activated carbon (GAC) and/or a natural zeolite, covered by a bacterial biofilm of Arthrobacter viscosus, were used in a continuous flow system to remove Cr (VI) from solutions with initial concentration of 70mg/l and a working pH ranging between 4.5 and 5.5. Three different set-up's were used: two columns in series filled GAC covered with a biofi...
متن کاملTreatment of Dairy Wastewater Using Pilot Scale Tricking Filter
A pilot scale trickling filter and secondary sedimentation are used to evaluate the feasibility of this process for the treatment of raw dairy waste. The BOD in the raw waste of 252 to 1200 mg/l is reduced 50-73% by a single stage and a further 17-55% by sedimentation tank. Treatment efficiencies are determined at various waste strengths and influent flow rates. With a loading rate of 5-12 kg B...
متن کاملGranular biochar compared with activated carbon for wastewater treatment and resource recovery.
Granular wood-derived biochar (BC) was compared to granular activated carbon (GAC) for the treatment and nutrient recovery of real wastewater in both batch and column studies. Batch adsorption studies showed that BC material had a greater adsorption capacity at the high initial concentrations of total chemical oxygen demand (COD-T) (1200 mg L(-1)), PO4 (18 mg L(-1)), and NH4 (50 mg L(-1)) compa...
متن کاملPecan shell-based granular activated carbon for treatment of chemical oxygen demand (COD) in municipal wastewater.
The present investigation was undertaken to compare the adsorption efficiency of pecan shell-based granular activated carbon with the adsorption efficiency of the commercial carbon Filtrasorb 200 with respect to uptake of the organic components responsible for the chemical oxygen demand (COD) of municipal wastewater. Adsorption efficiencies for these two sets of carbons (experimental and commer...
