Abstract

"FLOCULAçãO DE MATERIAL CELULAR". Um processo para floculação de material celular microbiano de um meio de suspensão que contém material celular, compreendendo adicionar ao meio de suspensão um primeiro material polimérico que é catiónico e possui viscosidade intrínseca de não mais do que 2 dl/g, e subseq³entemente ou simultaneamente adicionar ao meio de suspensão um segundo material polimérico que é catiónico ou substancialmente não-iónico e ter uma viscosidade intrínseca de pelo menos 4 dl/g, e deixar flocular o material celular.
