A solid – liquid – gas, multiphase reactor, called Inverse Fluidized Bed Bioreactor (IFBBR) was used in this study for the treatment of starch industry wastewater of high organic content and acidic nature. Mixed culture obtained from the sludge, taken from starch industry effluent treatment plant, was used as microorganisms. Experiments were carried out in an Inverse fluidized bed bioreactor, a...

Packed bed or rock bed is very commonly known thermal energy storage component for solar air heaters. The major concern for design of packed bed energy storage system is to maximize the heat transfer with minimum pressure drop or pumping power. Under the given operating conditions, system parameters could affect heat transfer and pressure drop in the bed considerably. An attempt has been made t...

Bioreactor technology has a considerable diversity in the production of fruit wines. During the past 20 years, immobilized cells have been explored for making high cell density reactors to simplify time-consuming procedures and to reduce labour requirements as well as cost. Amongst the immobilization techniques used, entrapment of yeast cells in alginate beads seem to be most simple and effecti...

Twelve basidiomycetes were investigated for their ability to degrade 13 industrial dyes and to treat four model wastewaters from textile and tannery industry, defined on the basis of discharged amounts, economic relevance and representativeness of chemical structures of the contained dyes. The best degradation yields were recorded for one strain of Bjerkandera adusta able to completely decolour...

The immobilization of Acidithiobacillus ferrooxidans cells on ceramic beads as carrier is described. The effects of ferrous ion concentration and dilution on the kinetics of ferrous ion oxidation in a packed-bed bioreactor were studied. In a medium containing 13.91 g of ferrous ion per litre, the fastest oxidation rate was 4.21 g L–1 at a dilution rate of 0.8 h–1. The corresponding conversion w...

This study provides the basis for implementing a continuous treatment system wastewater containing pesticide mixture formed by atrazine, iprodione, and chlorpyrifos. Two fungal strains (Verticilium sp. H5 Metacordyceps H12) isolated from biomixture of biopurification were able to remove different concentrations (10 50 mg L−1) efficiently liquid medium; however, half-life pesticides was reduced ...

Ethyl esters of omega-3 fatty acids are active pharmaceutical ingredients used for the reduction in triglycerides treatment hyperlipidemia. Herein, an ultrasonic packed-bed bioreactor was developed continuous production docosahexaenoic acid (DHA) and eicosapentaenoic (EPA) ethyl from DHA+EPA concentrate acetate (EA) using immobilized lipase, Novozym® 435, as a biocatalyst. A three-level–two-fac...
