Abstract
Se prezinta un procedeu de purificare a apelor reziduale, caracterizat prin folosirea drept coagulanti a unui amestec de saruri de fier, aluminiu si titan si de produse organice cu comportare de polielectroliti, obtinute prin tratarea la temperatura camerei, timp de 30 min, a namolurilor rezultate de la statiile de epurare a apelor reziduale, cu HCl 20% g, sau H2SO4 30% g, sau, de asemenea, cu ape reziduale acide cu concentratia corespunzatoare. A process for the purification of waste water, characterized by the use as a coagulant of a mixture of iron, aluminum and titanium salts and organic products with polyelectrolyte behavior, obtained by treating the resulting sludge at room temperature for 30 minutes from wastewater treatment plants with 20% g of HCl or 30% of H2SO4, or also with acidic waste water with the corresponding concentration.
