Abstract

"MéTODO E APARELHO PARA CLARIFICAR PASTA FLUIDA". A presente invenção se refere a um método de clarificar e/ou de espessar uma solução contendo sólidos, isto é, uma pasta fluida, e o aparelho para a realização disto. Utilizando o método e o aparelho em concordância com a presente invenção, o floculante a ser alimentado dentro do equipamento de clarificação e de espessamento é misturado uniformemente e com uma pequena força de cisalhamento dentro da pasta fluida no poço de alimentação do aparelho. O poço de alimentação está equipado com um dispositivo de misturação. A pasta fluida é tomada avançada (para a frente) a partir do poço de alimentação uniformemente dentro do tanque de clarificação no interior da camada de subfluxo, o que possibilita a separação de uma solução de sobrefluxo límpida (clara).
