About this Item

244 pages. Dimensions: 8.7in. x 5.9in. x 0.6in.A novel multi-stage external loop airlift reactor (MS-ELALR) has been designed to remove phenol and Cr(VI) from wastewater by means of their adsorption onto the surface of activated carbons. The multi-staging has been achieved by hydrodynamically induced continuous bubble generation, breakup and regeneration. The typical values of gas holdup, liquid circulation velocity, interfacial area and volumetric mass transfer coefficient of the MS-ELALR were found to be 0. 42-0. 66, 0. 04-0. 13 ms, 70-300 m2m3 and 0. 01-0. 5 s-1 respectively. Powdered activated carbons were prepared from four different biomasses by chemical activation and were used to remove Cr(VI) and phenol from wastewater in this MS-ELALR. The results obtained were encouraging and confirmed that both Cr(VI) and phenol can be effectively removed using the method of liquid-phase adsorption in the MS-ELALR. This item ships from multiple locations. Your book may arrive from Roseburg,OR, La Vergne,TN. Bookseller Inventory # 9783639298758

Synopsis:

A novel multi-stage external loop airlift reactor (MS-ELALR) has been designed to remove phenol and Cr(VI) from wastewater by means of their adsorption onto the surface of activated carbons. The multi-staging has been achieved by hydrodynamically induced continuous bubble generation, breakup and regeneration. The typical values of gas holdup, liquid circulation velocity, interfacial area and volumetric mass transfer coefficient of the MS-ELALR were found to be 0.42-0.66, 0.04-0.13 m/s, 70-300 m2/m3 and 0.01-0.5 s-1 respectively. Powdered activated carbons were prepared from four different biomasses by chemical activation and were used to remove Cr(VI) and phenol from wastewater in this MS-ELALR. The results obtained were encouraging and confirmed that both Cr(VI) and phenol can be effectively removed using the method of liquid-phase adsorption in the MS-ELALR.
