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...

The anaerobic treatability of malt whisky distillery wastewater was investigated. Biochemical methane potential (BMP) experiments were conducted both with and without basal medium (BM) to observe the effect of nutrient supplementation. For batch reactors containing no nutrients but only NaHCO3, net total gas production at the end of 29 days were observed as 0.019 m 3 gas/kg COD removed. With nu...

Under anaerobic conditions, organic pollutants in wastewater are degraded by microbes producing methane and carbon dioxide. The degradation process is effective compared to the more conventional aerobic processes and produces only 5-10% of sludge. This saves considerably on cost associated with the sludge disposal. Among anaerobic technologies, the most popular ones is the upflow anaerobic slud...

Potato starch was extruded and roasted with apple distillery wastewater to produce esters substituted malic acid residues. The esterification degree higher at the roasting temperatures. Starch modification contributed its darker color, increased resistance action of amylolytic enzymes, decreased solubility heat phase transition. changes in other properties examined depended on extrusion process...

Vinasse is a colored recalcitrant wastewater of the distillery industry. The aim of this work was to study the use of Phanerochaete chrysosporium for the vinasse degradation under two different growth conditions. Vinasse was treated by P. chrysosporium in a liquid inoculum form, during 32 days at room temperature (approximately 25 degrees C) and at 39 degres C. Chemical oxygen demand (COD), tot...

Distillery wastewater from the bioethanol industry contains a high level of organic content which can be converted into biogas. However, presence toxic compounds in this could inhibit biogas production. Therefore, prior detoxification distillery is required. Fenton, one Advanced Oxidation Process (AOP) methods, was selected due to its performance degrade pollutants, short reaction time, and pro...
