Abstract

L'invenzione concerne una composizione ed un procedimento che la utilizza secondo il quale è possibile rimuovere, dai reflui polari, economicamente e facilmente, dispersioni colloidali costituite da particelle solvatate.La composizione è caratterizzata da una sospensione, a concentrazione indicata, di montmorillonite in una parte dello stesso refluo da trattare. Detta frazione di refluo avrà, o sarà condizionata per ottenere, un pH compreso tra 5 e 9.La montmorillonite viene poi lasciata "attivare selettivamente", nella sospensione per almeno 1 ora.Il procedimento che utilizza detta composizione prevede che questa, dopo "l'attivazione selettiva" della montmorillonite, venga addizionata - sotto agitazione - al restante refluo da trattare (il cui pH sarà, o dovrà essere condizionato fino ad essere maggiore, di 2,5) fino ad ottenere una indicata concentrazione finale in montmorillonite. Continuando ad agitare si ottiene la precipitazione delle sostanze solvatate agglomerate alla montmorillonite.Per filtrazione, ad esempio, si ottiene rapidamente un filtrato limpido ed un residuo costituito dalla montmorillonite e dalle particelle che formavano la dispersione colloidale.
