EXTERNAL MASS TRANSFER MODEL FOR DEGRADATION OF SIMULATED TEXTILE EFFLUENT IN PACKED BED REACTOR

Packed bed reactor for degradation of simulated cyanide-containing wastewater

The discharge of cyanide-containing effluents into the environment contaminates water bodies and soil. Effective methods of treatment which can detoxify cyanide are the need of the hour. The aim of the present study is to develop a bioreactor for complete degradation of cyanide using immobilized cells of Serratia marcescens RL2b. Alginate-entrapped cells of S. marcescens RL2b were used for comp...

Biobleaching of Textile Dye Effluent Using Mixed Culture through an Immobilized Packed Bed Bio Reactor (IPBBR)

Determination of External Mass Transfer Model for Hydrolysis of Jatropha Oil Using Immobilized Lipase in Recirculated Packed-Bed Reactor

In this study, a simple and effective technique for establishing an external mass transfer model in a recirculated packed-bed batch reactor (RPBBR) with an immobilized lipase enzyme and Jatropha oil system is presented. The external mass transfer effect can be represented with a model in the form of Colburn factor JD = K Re. The value of K and n were derived from experimental data at different ...

Treatment Of Slaughterhouse Effluent Using Upflow Anaerobic Packed Bed Reactor

Most of the slaughterhouses in the state of Kerala (India) do not have proper and effective effluent treatment facilities. Collection of blood and separation of manure to reduce the very high organic load of the effluent are also not practiced. As a result, large volumes of extremely complex effluents with high content of fat, grease, and protein are discharged into land or water bodies causing...

Packed Bed Reactor Model for De-mercurization of Simulated Mercury-Laden Wastewater

Microbial reduction of soluble bivalent mercury to its less toxic elemental metallic form was performed using mercury-resistant Bacillus cereus (JUBT1) isolated from the sludge of chloralkali industries. A lab-scale 1 m long and 0.05 m diameter packed bed biofilm reactor was designed to remove mercuric ions (Hg) using isolated bacterial consortium. The bioreactor was continuously fed with steri...
