Municipal, agricultural and industrial liquid or solid wastes differ very much in their chemical, physical and biological
characteristics. The diverse spectrum of wastes requiring efficient treatment has focused the attention of researchers on
membrane, ion-exchange and biological technologies. The most effective and ecological technological systems developed
during the past 20 years are as a rule based on a combination of the chemical, physical and biological methods. Anaerobic
digestion, anaerobic filters, lagoons, activated sludge and trickling filters have all been successfully applied to the treatment
of distillery wastewater. Membrane and membrane separation techniques with immobilized microorganism or enzyme have
very significant role in treatment of distillery wastewater.
