Media Optimization for the Decolorization of Distillery Spent Wash by Biological Treatment using Pseudomonas Fluorescence
The wastewater released from distilleries and fermentation industries are the major source of soil and aquatic pollution due to presence of water-soluble recalcitrant colouring compounds called melanoidins. Biological decolourisation of of these compounds found more advantages compared to chemical treatments. Hence in this study, the bacterium Pseudomonas fluorescens showing higher decolorizati...
متن کاملDecolorization of Distillery Spent Wash Using Biopolymer Synthesized by Pseudomonas aeruginosa Isolated from Tannery Effluent
A bacterial strain was isolated from tannery effluent which can tolerate high concentrations of potassium dichromate up to 1000 ppm. The isolated microorganism was identified as Pseudomonas aeruginosa by performing biochemical tests and molecular characterization. In the presence of excess of carbohydrate source, which is a physiological stress, this strain produces Polyhydroxybutyrate (PHB). T...
متن کاملTreatment Processes and Technologies for Decolourization and COD Removal of Distillery Spent Wash: A Review
Most of distilleries in India use biomethanation process to treat the spent wash generated during the alcohol process, to ensure the effective treatment all distillery industries follow 13 fold dilutions due to which tremendous amount of spent wash is generated. 8 -15 l of spent wash was generated during 1 l of alcohol, thus distillery industries consume more water and produce waste water on a ...
متن کاملNanofiltration and Reverse Osmosis Process for the Treatment of Distillery Spent Wash
Thin-film composite nano-filtration (NF) and reverse osmosis (RO) membranes based NF followed by ROpilot plant at a feed pressure of 20 atm.and flow rate of 10 L/min. was used to remove colour, total dissolved solid (TDS) and chemical oxygen demand (COD) of distillery spent wash. NF was found to be effective for high rejection of TDS, colour and COD by 85%, 99% and 95%, respectively. Furthermor...
متن کاملEffect of transport phenomena of Cladosporium cladosporioides on decolorization and chemical oxygen demand of distillery spent wash
The focus of this report is directed towards the influence of transport properties of fermentation broth in degradation and decolorization of distillery spent wash using Cladosporium cladosporioides. Batch experiment was conducted in a bioreactor for 7 days with 250 rpm at 35 C under optimum bioprocess conditions maintained using control system. Results of the morphological analysis revealed th...
