Abstract
"PROCESSO E DISPOSITIVO PARA O AREJAMENTO DE SUSPENSõES". A presente invenção refere-se a um processo para o arejamento de suspensões, em particular, para a flutuação, por exemplo, durante a remoção de tinta de suspensões de matéria fibrosa, com um ou mais estágios e/ ou células P1, P2, P3, P4, S1, S2, sendo que, em cada estágio/célula P1, P2, P3, P4, S1, S2 está previsto um circuito líquido 6 próprio separado. Para o aperfeiçoamento da separação das cinzas, de acordo com a invenção está previsto que seja intercalado um processo de lavagem 12, 12<39>, 16, 18. Além disso, a invenção refere-se a um dispositivo para a execução do processo.
