  • What are physico-chemical methods of distillery wastewater treatment?
  • Physico-chemical methods of distillery wastewater treatment combine physical and chemical processes, where the former process aids in removal of suspended materials and reduction of soluble COD can be achieved by the later process.
  • Can distillery waste be used as a substrate?
  • Lab and field scale use of distillery waste as a substrate has been highlighted. Ethanol distillation generates a huge volume of unwanted chemical liquid known as distillery wastewater. Distillery wastewater is acidic, dark brown having high biological oxygen demand, chemical oxygen demand, contains various salt contents, and heavy metals.
  • Is there a catalytic sub-and supercritical water treatment for distillery wastewater?
  • In the current research, we have studied the catalytic sub- and supercritical water (SCW) treatment of distillery wastewater (DWW) in a batch tubular reactor. Experiments were conducted in the temperature range of 250–400 °C, reaction time of 30–120 min at constant pressure of 25 MPa with the aim of chemical oxygen demand (COD) and color removal.
  • Can distillery wastewater be managed effectively?
  • So, there is an urgent need for its proper management. For this purpose, a group of researchers applied distillery wastewater for fertigation while others focused on its physico-chemical, biological treatment approaches. But until now no cutting-edge technology has been proposed for its effective management.
