Abstract

Perfezionamento ad un metodo e relativo prodotto per la depurazione particolarmente delle acque inquinate da fosforo, azoto, metalli pesanti e solventi clorurati, ammettendo in esse, a seconda del tipo di abbattimento, un composto liquido sostanzialmente costituito da acido umico e fulvico, od acido umico e fulvico più un sale metallico, e più in particolare: l'acido umico e fulvico essendo estratto dalla lignite, leonardite, fossili di origine vegetale, come la torba, vi è contenuto nella misura dal 1% al 21%; mentre il sale metallico, come l'allume potassico, essendo aggiunto successivamente alla dispersione nelle acque da trattare di un composto ottenuto da acido umico ed acido fulvico, è contenuto nella misura dall'1% al 6%.
