Jackson et al. (2007) used a bioreactor system to treat distillery wastewater with a two-week HRT. COD of the distillery wastewater was decreased from 2255 mg/l to a final value of 5 150 mg/l. Some of the aerobic systems being applied for treatment of distillery wastewater are summarized in Table 7.
2018/3/1/ · In distillery wastewater (DWW), melanoidins are the major coloring pollutants causing serious environmental problems and health threats in human and animals (Tamanna and Mahmood, 2015, Saranraj and Dtella, 2014).Melanoidins are recalcitrant compounds of sugar and amino acids, formed during the processing of sugar cane juice in sugar factories
2020/6/1/ · Due to the batch manufacturing stages of whiskey distillery, high-strength waste streams (distillery WW, spent wash) were mixed with dilution wastewater (sewage)
wastewater. A total amount of about 2 m3 was collected from a distillery located in South Italy (Sicily) and, after a preliminary characterization, the inlet wastewater was properly stored into a stirred and refrigerated (2e4 C) tank, also used as feeding unit. The pilot scale tests involved three treatment steps arranged in
2017/4/1/ · Raw distillery wastewater (RSW) has the characteristics such as pH 4.0–4.6; chemical oxygen demand 85,000–110,000 ppm; total dissolved solids 85,000–110,000 ppm and biological oxygen demand 25,000–35,000 ppm. Isolation and characterization of aerobic bacteria capable of the degradation of synthetic and natural melanoidins from ...
2018/10/13/ · The most widespread aerobic wastewater treatment is the activated sludge in which a efforts are targeted at enhancements in the reactor design and performance. For instance, aerobic sequencing batch reactor (SBR) was reported to be a hopeful solution for the wineries treatment (Torrijos and Moletta 1997). Aerobic reactor reduces 93% COD and
1993/1/1/ · Wine-distillery wastewater has a high organic pollutant load (40 g COD/litre) which includes various phenolic compounds, the major ones being gallic acid, p-coumaric acid and gentisic acid. Partial removal of some of the organic matter and phenolic compounds by aerobic pretreatment with Geotrichum candidum is described in this study. This ...
The distillation process has three main steps: Step 1: The fermentation of the carbon (sugar) source: The substrate – e.g. molasses from sugar cane (molasse is the residual syrup from sugar production from which no crystalline sucrose can be obtained by simple means) – is brought into contact with yeast cultures.
2012/6/1/ · The alcohol distilleries are growing extensively worldwide due to widespread industrial applications of alcohol such as in chemicals, pharmaceuticals, cosmetics, beverages, food and perfumery industry, etc. The industrial production of ethanol by fermentation results in the discharge of large quantities of high-strength liquid wastes. Distillery wastewater is
This chapter provides the detailed information on the generation, characteristic, toxicity as well as various biological employing bacteria, fungi, microalgae, etc. for the treatment of distillery wastewater. Distillery industries are one of the major sources of environmental pollution because these industries discharge a huge volume of dark-colored wastewater
Distillery stillage has high levels of nutrients, such as nitrogen, phosphorus, potassium, and also of total solids, total dissolved solids, total suspended solids, sulfate, and iron. Table 2 presents the physical and chemical properties of wastewater from
Distilleries produce wastewater at several stages of the process, including distillation, condenser cooling, fermenter cooling, fermentation, and washing. The majority of this effluent is produced during the distillation and condenser cooling stages. The characteristics of the wastewater produced are determined by the feedstock used.
The thermal treatment of highly polluted wastewater from distilleries is considered an economical and effective supplement to the anaerobic digestion and oxidation processes. Heating the stillage at high 展开

2017/7/1/ · The initial cassava distillery effluent, called raw distillery wastewater, was heavy in organic carbon, dark brown in color and acidic in pH. The anaerobically-aerobically combined processes were used as the primary treatment of the raw stillage, and results are given in Table 1.By means of anaerobic digestion, approximately 94% of soluble COD was …
