Fixed Bed Biosorption Using Aquatic Macrophyte in Lead Removal
Adsorption process is an efficient alternative in metal ions removal. Many materials can be used in this process; among them, we can cite biological materials such as aquatic macrophytes. The macrophytes have shown a high percentage of metal ions removal and they have an advantage of being low cost and have the possibility of growing. In view of this, the aim of this work is evaluate lead remov...
متن کاملAn analysis of a trickle-bed bioreactor: carbon disulfide removal.
An analysis of the local processes occurring in a trickle-bed bioreactor (TBB) with a first-order bioreaction shows that the identification of the TBB operating regime requires knowledge of the substrate concentration in the liquid phase. If the substrate liquid concentration is close to 0, the rate-controlling step is mass transfer at the gas-liquid interface; when it is close to the value in ...
متن کاملSolid state biosurfactant production in a fixed-bed column bioreactor.
Biosurfactants are surface active substances which reduce interfacial tension and are produced or excreted at the microbial cell surface. We evaluated the biosurfactant production by Aspergillus fumigatus and Phialemonium sp. in solid state processes using fixed-bed column reactors. We evaluated two media, rice husks alone (simple support) and rice husks plus defatted rice bran (complex support...
متن کاملRemoval of gaseous toluene using immobilized Candida tropicalis in a fluidized bed bioreactor
A pure yeast strain Candida tropicalis was immobilized on the matrix of powdered activated carbon, sodium alginate, and polyethylene glycol (PSP beads). The immobilized beads were used as fluidized material in a bioreactor to remove toluene from gaseous stream. Applied toluene loadings were 15.4 and 29.8 g/m(3) h in Step 1 and Step 2, respectively, and toluene removal was found above 95% during...
متن کاملRemoval of trace organics from water using a pumped bed-membrane bioreactor with powdered activated carbon
A pumped bed-membrane bioreactor (PB-MBR) combining powdered activated carbon (PAC) adsorption with bacterial degradation was studied for the purification of tap water, spiked with 2 mg/l of phenanthrene, to sub-ppm levels. The feedwater was supplemented with nitrogen and phosphorous to reach a COD:N:P ratio of 100:10:1. PAC concentration was maintained at 5 g/l. Polyacrylonitrile (PAN) flat-sh...
