Zusammenfassung:The invention relates to a process for purifying heavy metal-containing industrial effluents. According to the invention, the process consists in passing the water to be treated through a column with filtering cartridges containing zeolitic volcanic tuff having a content of SiOand AlO, thereafter the heavy metal ions are replaced, by an adsorption-desorption type reaction, with the mobile ions of the zeolite, thereby resulting filtered water for industrial use. Invenţia se referă la un procedeu de epurare a apelor industriale uzate, cu conţinut de metale grele. Procedeul conform invenţiei constă din trecerea apei de tratat printr-o coloană cu cartuşe filtrante, conţinând tuf vulcanic zeolitic cu conţinut de SiOşi AlO, în urma căreia ionii de metal greu sunt înlocuiţi, printr-o reacţie de tip adsorbţie-desorbţie, cu ionii mobili ai zeolitului, din care rezultă apă filtrată, pentru uz industrial.
