In the recent years, strong efforts have been made to develop sustainable biocatalytic decolorization processes for dye-polluted water resulting. In particular dye-oxidizing laccase enzymes immobilized on suitable carriers are promising candidates, which can be reused as long as the activity is sufficiently high.
In that field loofa is excellent candidate of naturally grown porous material, based developed methodology to immobilize laccase from Trametes hirsute on natural-grown and decomposable cellular loofa sponge carrier which was done in in previous step, however still the scale up of the reaction test and exam the treatment process by moving from batch to continuous system needs to be done in a developed reactor which designed for this aim. A novel X- loop airlift fluidized reactor is designed to provide satisfying mass transfer rate and system intensity for the decolorization.
The main goal is to experimentally investigate the dye removal in this novel reactor
The project involves the following tasks:
-Literature review on the current understanding of airlift biochemical reactor and immobilization of enzyme
-Enzyme Bio-catalysis preparation with highest bio-catalysis activity and stability
-Characterization the dye removal to identify the favorable operation condition in terms of dye concentration, treatment time and gas and fluidizing velocity
-Establish a model or correlation to prediction the removal process

• Student in the field of chemical engineering, process engineering, bioprocess engineering or similar professional orientation.
• Good English language skills.
