Anaerobic Treatment of Distillery Wastewater
The estimated global ethanol production in 2009 was about 74 mln m. After fermentation remains waste from bottom of distillation columns, termed stillage. This highly aqueous residue containing organic solubles is considered a troublesome and potentially polluting waste due to its extremely high BOD and COD values. Moreover, for each liter of produced ethanol 8 -15 liters of stillage are genera...
متن کاملPreparation and Performance Studies on Polyethersulfone Ultrafiltration Membranes Modified with Gelatin for Treatment of Tannery and Distillery Wastewater
In this study polyethersulfone ultrafiltration membrane were prepared with the modifier gelatin at 0, 5, 10, 15 and 20 wt % using DMF as solvent by phase inversion process. Morphologies and characteristics of the membranes were investigated through the methods of SEM, XRD, contact angle measurements. The performance of the modified membrane for the treatment of leather and distillery wastewater...
متن کاملUltrasound and enzyme assisted biodegradation of distillery wastewater.
Irradiation with ultrasound (US) and use of an enzyme (E) as pretreatment techniques were carried out to treat a complex effluent (distillery wastewater). These two techniques have been used alone as well as in combination and the efficacy of these techniques was tested by subjecting the effluent to subsequent aerobic biological oxidation (AO). When used alone, US exposure for 30 min and 2 h yi...
متن کاملAnaerobic Methods of Distillery Waste and Wastewater Treatment
During alcohol production, large amounts of waste and wastewater are produced. These may have a considerable environmental impact by polluting both water bodies and soil, by causing an adverse climatic effect and odour nuisance. Due to the high concentration of organic matter, both distillery waste and wastewater at the same time do have a great nutrient and energy potential that can be utilise...
متن کاملNutrient recovery from the dry grind process using sequential micro and ultrafiltration of thin stillage.
The effectiveness of microfiltration (MF) and ultrafiltration (UF) for nutrient recovery from a thin stillage stream was determined. When a stainless steel MF membrane (0.1microm pore size) was used, the content of solids increased from 7.0% to 22.8% with a mean permeate flux rate of 45L/m(2)/h (LMH), fat increased and ash content decreased. UF experiments were conducted in batch mode under con...
