Application of hydrocyclones for removal of yeasts from alcohol fermentations broths

In this research work the possibility of using hydrocyclones to separate Saccharomyces cerevisiae 5209 from prepared media was studied. The cell separation can be very useful in order to improve the quality of alchol produced, reduce energy consumtion and also reduce the cost of effluent treatments with the hydrocyclone advantage of consuming liss energy. A hydrocyclone with 22.3 mm internal diameter was used for cell separations. A better separation efficiency of more than 2 (cells dry weight in under flow / over flow) was obtained at low volume flow eates of about 46 Cm³/Sec
