title: Performance evaluation of vinasse treatment plant integrated with physico-chemical methods.
abstract: With an objective to assess environmental management criteria of a vinasse treatment plant (VTP) and to evaluate the critical environmental parameters, a study was undertaken in a multi-product (packaged apple juice, distillery, brewery, packaged drinking water) brewery-cum-distillery unit. The facility with a volumetric loading rate of 11-15 kg COD m(-3).day, 3.6-4.5 h hydraulic retention time and 20 g l(-1) VSS had a scientifically managed technically sound effluent treatment system. While the water quality parameters were found within the acceptable limits, there was 99.07% reduction in BOD, from 43140.0 to 398.0 mg l(-1) and 98.61% reduction in COD from 98003.0 to 1357.0 mg l(-1). There was appreciable improvement in mixed liquor suspended solids (MLSS), mixed liquorvolatile suspended solids (MLVSS) and sludge volume index (SVI). A striking feature was the integrated aerobic-anaerobic highly efficient Up-flow Anaerobic Sludge Blanket (UASB) treatment for biodegradation and energy production that reduced energy and space needs, producing utilisable end-products and net savings on the operational cost. The end-point waste management included terminal products such as fertile sludge, cattle feed supplement, recyclable water and biogas. Vast lagoons with combined aerobic-anaerobic approaches, biogasification unit, sludge recovery, remediated irrigable water were the notable attributes.
