Abstract

"DECANTADOR LONGITUDINAL CONTìNUO COM SEPARAçãO DE FLUXOS". Decantador longitudinal contínuo com separação de fluxos caracterizado pelo fato de que ele compreende: - uma zona (1) de entrada do líquido a tratar que compreende um sistema de distribuição desse líquido; - uma zona (2) de homogeneização do escoamento que assegura uma dissipação da energia de entrada e um perfil de velocidade regular e sensivelmente plano na saída dessa zona; - uma zona útil de decantação (3) que apresenta um escoamento homogêneo ao longo da qual é mantido um perfil de velocidade regular e sensivelmente plano assim como um número de Froude elevado que garante a estabilidade do escoamento do líquido e; - uma zona de separação e de recuperação dos fluxos (4), situada na extremidade jusante do decantador, o líquido tratado sendo evacuado na superfície e as matérias decantadas pelo fundo do decantador.
