Abstract
The currently used traditional method of waste water treatment based on the precipitation of heavy metals by iron hydroxide formed at the time of neutralization (liming) / bleach(active chlorine) doesn’t correspondent to the standards of maximum permissible concentration (MPC) in practical meaning. In this regard, the urgent task is the use of natural materials as sorbents due to the relatively high sorption capacity, selectivity, having cation-exchange properties and the possibility of almost complete removal of heavy metal ions. Another important factor is their relatively low cost and availability (sometimes as alocal material). We believe that the use of scientific-based combinations of different ways in waste water treatment based on the success of modern chemistry allows opening newand perspective opportunities in this area.Key Words: Waste Water, Metallurgy, Bentonite, Zeolites, Groundwater
