Ozone assisted electrocoagulation for the treatment of distillery effluent

Effects of untreated and treated oilfield-produced water on seed germination, seedling development, and biomass production of sunflower (Helianthus annuus L.)

“…A major amount of coagulant magnifies the hydrophobicity of oil droplets and reduces electrostatic repulsion between air bubbles and oil droplets, favoring its flotation and intensifying oil removal. However, these factors raise mass wear of iron electrodes and energy consumption in the process (Asaithambi et al 2012;Farhadi et al 2012).…”

Comparison of treatment and energy efficiency of advanced oxidation processes for the distillery wastewater

“…Few researches focused on distillery effluent treatment using AOP. Asaithambi et al (2012) studied ozoneassisted electrocoagulation for the treatment of effluent, and they observed ozone-assisted electrocoagulation was more effective than electrocoagulation and ozonation alone. The photodegradation of effluent in the presence of solar radiation and the result shows 79 % color removal under the optimum conditions of H 2 O 2 , pH and catalyst by Vineetha et al (2013).…”

“…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.…”

Decolorization of distillery spent wash effluent by electro oxidation (EC and EF) and Fenton processes: A comparative study

“…This is due to the fact that, with an increase in agitation speed, the movement of the generated ions increases leading to higher interaction between the ions. A further increase in the agitation speed beyond the optimum value, the flocs gets broken and the aggregated organic content gets dissipated back to the solution causing a decrease in the removal efficiency of organic matter (Asaithambi et al, 2012;Khandegar and Saroha, 2012).…”
