Abstract

sistema de recirculação de lama, e, método para criar um comportamento de fluxo de fluido particular. um processo para tratamento de água, incluindo uma combinação de métodos do grupo compreendendo coagulação, sedimentação, floculação e floculação de lastro, que é ainda aperfeiçoada pela adição de um sistema simplificado de recirculação de lama. o sistema de recirculação, correspondendo a este processo, permite mais elevada densidade de lama, bem como perdas de volume d'água menos significativas, fazendo-se o acúmulo de lama no fundo da zona de sedimentação atravessar um hidrociclone por um certo número de vezes em ciclos repetidos, assim aumentando a densidade de partículas sólidas da lama extraída. o sistema pode também ser controlado por um analisador de sólidos suspenso, um medidor de fluxo e/ou um regulador. a presente invenção também inclui um método de produzir comportamento específico de controle de fluxo de fluido com este sistema de reticulação de lama simplicado, que, além disso, melhora a eficiência do processo.
