Wastewater Treatment by Novel Polyamide/Polyethylenimine Nanofibers with Immobilized Laccase

Ammonia Wastewater Treatment by Immobilized Activated Sludge

Treatment of Wool Scouring Wastewater by Immobilized Chitosan Bio-Membrane

A Chitosan/sucrose/polyurethane composite bio-membrane was prepared by the facile drop coating method. The composite bio-membrane had a porous spongy structure composed of a physical mixing of each component. The water absorbability of the composite bio-membrane increased with increasing chitosan and sucrose contents. Furthermore, the composite bio-membrane with immobilized Aspergillus sojae ex...

The methods of treatment of wastewater briefly discussed. Special attention has been paid to the biological treatment mentioning the drawbacks of the traditional methods. The relative advantages of var...

Modeling of immobilized cell columns for bioconversion and wastewater treatment.

Immobilized cells are widely used in bioconversions to produce biological products as well as in wastewater treatment such as solvent removal from wastewater streams. In this work, a rate model is proposed to simulate this kind of process in an axial-flow fixed-bed column packed with porous particles containing immobilized cells. The transient model considered various mass transfer mechanisms i...

Decolorization of reactive dyes by laccase immobilized in alginate/gelatin blent with PEG.

To achieve effective decolorization of reactive dyes, laccase immobilization was investigated. Laccase 0.2% (m/V) (Denilite IIS) was trapped in beads of alginate/gelatin blent with polyethylene glycol (PEG), and then the supporters were activated by cross-linking with glutaraldehyde. The results of repeated batch decolorization showed that gelatin and appropriate concentration of glutaraldehyde...
