Abstract
"MéTODO E COMPOSIçãO PARA TRATAMENTO DE REPRESAMENTO DE FOSFATO EM UM CORPO DE áGUA". Composições incluindo pelotas de alume, um material mineral de esmectita e opcionalmente carbonato de sódio ou de cálcio, que pode ser suprida para um represamento de fosfato localizado no fundo de um corpo de água. As pelotas de alume, material mineral de esmectita e opcionalmente carbonato de sódio ou de cálcio são deixadas cair através do corpo de água de tal modo que o alume é liberado quando a pelota alcança o fundo do represamento tratando deste modo os fosfatos.
