Colloidal particles in water can be trapped when these precipitates in the formation of metal salts (such as aluminum sulfate or ferric chloride) or metal oxides and hydroxides (such as lime) as a coagulant, www.lvliao, when the vote The amount added is large enough to rapidly precipitate metal hydroxides such as Al (OH3, Fe (OH) 3, Mg (OH) 2 or metal carbonates such as CaCO3.
