ABSTRACT:
Direct
discharge of municipal and industrial waste waters and leachate (originating
from the illegal landfills) into recipients without prior purification is
unfortunately very common practice in the region of northern Kosovo. In
addition, irresponsible and incorrect selection of sites for industrial and
municipal dumps, which are often located in vicinity or on actual river banks,
contributes significantly to environmental pollution. Analysis of the leachate
from such sites was done by direct sampling and by using TCLP (Toxicity
Characteristic Leashing Procedures) method. Based on the analysis of
physicochemical parameters of the filtrated water from the sites Zitkovac,
Grabovac and Balaban and analysis of the samples of surface water and
groundwater from the site Grabovac, possible steps for removal and reduction of
the existing pollution were proposed. Potential permanent solution in form of
purification of municipal and industrial waste waters as well as leachate from
illegal landfills was suggested. The potential implementation of remediation
with a unified system for water purification, by using Membrane Bio Reactor
(MBR), which includes the process of stabilization/solidification of a residual
sludge, would have as an end product a neutral powder material completely safe
for the environment, suitable for a variety of applications.
