“…These treatment processes require high capital and operating cost. Among various technologies, electrochemical (EC) treatment is one of the best economical alternative processes (Chen 2004;Ponselvan et al 2009) when conventional treatment methods fail to reduce pollution among industrial effluents (Brillas et al 1998). EC process is a recently developed technique which is being employed in the treatment of various wastewaters (Kim et al 2002;Aoudj et al 2010;Serge et al 2010;Kamaraj et al 2013;Maleki et al 2014;Ndjomgoue-Yossa et al 2014).…”

In the present study, electrochemical (EC) treatment of sugar industry wastewater (SIWW) was investigated using aluminum electrode. Effect of various parameters such as pH, current density (CD), electrode gap and electrolysis time was evaluated for chemical oxygen demand (COD) and color reduction. Energy requirement and electrode loss were found to increase with an increase in pH. Kinetics studies showed that the COD reduction rate was second order with respect to organic materials (COD) and 0.591 order with respect to CD. Filtration of treated slurry was found to be best near the neutral pH, while settling was best at pH 10. Operating cost of the treatment has been calculated. Results demonstrate that EC can be applied to reduce pollution load of SIWW.

“…Research has been carried out on the treatment of distilleries wastewater. Various conventional methods have been adopted such as biological flocculation (Zhang et al 2009), nanofiltration (Rai et al 2008), activated carbons (Satyawali and Balakrishnan 2007), bioelectrochemical process (Mohanakrishna et al 2010), ozonation-based process (Sreethawong and Chavadej 2008;Lucas et al 2010;Asaithambi et al 2012), electro-oxidation (Piya-areetham et al 2006;Thakur et al 2009), membrane-based nanofiltration and reverse osmosis (Nataraj et al 2006) and electrocoagulation (Ponselvan et al 2009). However, conventional methods found to be techno-economically non-feasible for the treatment of organic pollutant present in the effluent.…”

The treatment of distillery effluent was investigated experimentally by various advanced oxidation processes such as Fenton and ozone with different combination of UV and H 2 O 2 system. The effect of operating parameters such as hydrogen peroxide concentration, initial effluent pH and Fe 2? concentration on Fenton system for the percentage color and chemical oxygen demand removal has been studied. The energy per order was also calculated for the advanced oxidation process. The ozone-photoFenton system has been observed that 100 % color and chemical oxygen demand removal compared with other process studied in the present investigation within 4 h of treatment time. Electrical energy per order has been calculated for all the process and found that ozone-photoFenton shows lesser energy consumption of about 0.01 kWh/m 3 order 1 , for the complete color and chemical oxygen demand removal.

Abstract-Biologically treated spentwash from distillery usually contains high chemical oxygen demand (COD), biological oxygen demand (BOD), color, total dissolved solids (TDS) and other contaminants. In India, reverse osmosis (RO) treatment plants have been installed in many of the distilleries at tertiary treatment, but are not properly working due to fouling problem. To make the membrane process proven and reliable technology, proper pre-treatment is mandatory which not only improve quality of RO permeate but also increase life of RO. In the present study, use of micro-filtration (MF) for pre-treatment of RO has been evaluated at the tertiary treatment stage. Experiments were optimized in terms of different operating parameters viz. initial pH (pH o : 2-10), trans-membrane pressure (1-5 bars) and temperature (15-43°C). Experimental data revealed that the MF could be an effective pre-treatment in removing the pollutants (COD, color and TOC) and improving performance and water recovery (permeate flux) in comparison to RO alone. Removal efficiency for COD, color, TDS and TOC was observed as 31.5%, 42.7% and 27.6% with MF, respectively at optimized conditions with increased permeate flux from 17. LPH (RO) to 32 LPH (MF-RO).Index Terms-Bio-digested distillery spentwash, life cycle assessment, pre-treatment, reverse osmosis, response surface methodology, micro-filtration.
