DEPHY project: Distillery wastewater treatment through anaerobic digestion and phycoremediation—A green industrial approach

Thermo gravimetric and kinetic studies on dried solid waste of post-methanated distillery effluent under oxygen and nitrogen atmosphere

“…The bottom product of the distillation column is termed as spent wash (Mohana et al, 2009). The unutilised sugar available in the spent wash is in complicated form called melanoidin, being the major reason for its colour and odour (Sankaran et al, 2014). The formation of melanoidin is due to high temperature maintained in distillation column.…”

“…The effluent received after anaerobic treatment is called Post-Methanation distillery Effluent (PME). The PME still contains, total suspended solid of (22,000-34,000 ppm), total dissolved solids of (35,000-45,000 ppm) and C.O.D of (25,000-40,000 ppm) (Sankaran et al, 2014), which indicates the possible high organic loading rate of the treated effluent.…”

“…Presently, distillery plants are using reverse osmosis (R.O) process or mechanical evaporator system after anaerobic digester for zero discharge. The problem with the reverse osmosis process is the high initial investment due to membrane cost, frequent membrane replacement and higher operational cost due to high energy requirement to overcome high pressure drop across the membrane (Sankaran et al, 2014). R.O reject will contains more complicated which requires further treatment process before discharging.…”

The Environmental Biorefinery: Using Microalgae to Remediate Wastewater, a Win-Win Paradigm

“…Industrial wastewaters from molasses-based distilleries are generated in large volumes (15 L of effluent per liter of alcohol produced) with high Biological Oxygen Demand (BOD) and COD concentrations (average ranges of 40-50 gO 2 /L and 80-100 gO 2 /L, respectively) [37]. The COD of a pH-adjusted alcohol distillery wastewater (pH = 6.0-7.0) could be decreased from 20 to 1.5 gO 2 /L in 3 days in a 50 L PBR using Chlorella sorokiniana (with a 95% decrease in nitrate, 77% in phosphate and 35% in sulfate) [38].…”

Assessment of land cover relocation incorporating the effects of human activity in typical urban and rural catchments for the design of management policies

“…Forest regions previously considered to be wasteland have been developed into productive farms. As agricultural practices have developed, the increasing population has become concentrated largely in cities and mega-cities during the last three decades (Lu and Campbell, 2009;Lo and Yeung, 1996;Mouri and Oki, 2010;Mouri et al, 2013b;Nastar, 2014;Rouillard et al, 2014;Sankaran et al, 2014). The shift from rice fields to urban land-uses requires landform transformation using landfill to protect against floods.…”
