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...

Raw bagasse, Bagasse fly ash and distillery sludge, the waste generated in sugar mills and distillery have been used as lowcost potential biosorbent for the removal of hexavalent chromium from an aqueous solution. The effect of hydrogen ion concentration, contact time, adsorbent dose, initial concentrations of adsorbate and adsorbent dose on the uptake of chromium were studied in batch experime...

Phenolic composition and radical scavenging activity in the shochu distillery by-products of sweetpotato (Ipomoea batatas L.) treated with koji (Aspergillus awamori mut.) and cellulase (Cellulosin T2) were investigated to develop new uses. Koji and Cellulosin T2 treatment of shochu distillery by-products from sweetpotatoes, rice, and barley increased phenolic content. Caffeic acid was identifie...

in this paper, startup performance of upflow anaerobic hybrid reactor and upflow anaerobic sludge blanket reactors in anaerobic treatment of distillery spentwash has been studied under identical conditions of operation. various effluent characteristics like ph, electrical conductivity, chemical oxygen demand, biochemical oxygen demand and total solids and other process parameters like biogas pr...

Pseudomonas sp. RZS1 was isolated from distillery effluent and identified based on phenotypic characters and 16s rRNA sequencing. It accumulated optimum amount (703.79 microg/mg of biomass) of poly-beta-hydroxybutyrate (PHB) under aerobic process of fermentation and 75 microg/mg of biomass under the anaerobic process of fermentation. Aerobic fermentation yielded 9.3-fold more PHB than semi-aero...

Sugarcane-molasses-based post-methanated distillery waste is well known for its toxicity, causing adverse effects on aquatic flora and fauna. Here, it has been demonstrated that there is an abundant mixture of androgenic and mutagenic compounds both in distillery sludge and leachate. Gas chromatography-mass spectrometry (GC-MS) analysis showed dodecanoic acid, octadecanoic acid, n-pentadecanoic...

This study was conducted at the ethanol plant of Metehara sugar factory, a laboratory scale, to assess effect recycling vinasse into fermentation process on effluent reduction. Vinasse is an produced from distilleries. The experimental design included concentrations 4 dilution rates (0 (control), 20, 35, 50, and 65% water) with 2 replicates 6 responses, as follows: yield, efficiency, residual c...
