Abstract

''APARELHO PARA A DISSOLUçãO DE UM GáS E A SUSPENSãO DE UM SóLIDO DE SEDIMENTAçãO DENTRO DE UM CORPO DE LìQUIDO, E, PROCESSO DE AERAçãO DE UM CORPO DE LìQUIDO E DE SUSPENSãO DE SóLIDOS DE SEDIMENTAçãO'' Um aparelho e um processo para mistura de um gás e um líquido com concomitante mistura e suspensão de sólidos e lodo no fundo de um tanque profundo. A presente invenção compreende um aerador de gás-líquido que está adaptado para ser submerso abaixo da superfície de água servida dentro de um tanque profundo. Uma mistura de gás-líquido de alta velocidade de expansão é forçada a sair do fundo do dispositivo aerador submerso com força suficiente para misturar e suspender lado e sólidos de sedimentação no fundo do tanque profundo.
