Abstract
MELHORIA DO EQUILÍBRIO HÍDRICO EM UM PROCESSO DE TRATAMENTO DE EFLUENTES PARA REMOÇÃO DE SULFATO. Um método para melhorar a separação sólido/sólido entre uma suspensão contendo trihidróxido de alumínio amorfo e uma suspensão contendo gesso em uma solução de sulfato de cálcio saturada sem a necessidade de uma etapa de desague após a separação sólido-sólido.IMPROVEMENT OF WATER BALANCE IN AN EFFLUENT TREATMENT PROCESS FOR SULFATE REMOVAL. A method for improving solid/solid separation between a suspension containing amorphous aluminum trihydroxide and a suspension containing gypsum in a saturated calcium sulfate solution without the need for a dewatering step after solid-solid separation.
