Abstract

The growing urban population in the cities
consequently leads to a steady increase in activities in
industrial sector, especially in agriculture and farming,
thus influence the increased sewage and wastewater
generation, respectively. These activities, pose a threat to
human health, generating excessive content of pollutants
with different chemical compositions in wastewater.
Among many pollutants, the ones with bonded nitrogen
atoms in form of organic compounds, ammonia and
nitrite/nitrate ions, interconvert in wastewaters causing an
eutrophication of the aquatic eco-systems (Wang et al.,
2010). Furthermore, reduction of nitrates into nitrites is
associated with nitrosamines generation, which increase
the prevalence of liver cancer, for example (Hosseini et
al., 2011). The extent of the wastewater treatment is
estimated based on the correlation of the inlet parameters
of an influent (wastewater before treatment) and the outlet
parameters of an effluent (treated wastewater). The extend
of fluctuation in water flow, chemical composition and
temperature, due to weather conditions annual variations,
impacts the capacity for chemical and biological
treatment of wastewater in the wastewater treatment plant.
Designing mathematical models based on Linear
Regression analyses using the correlated data sets of
influent and effluent offer opportunity for prediction
SWOT analyses for the efficiency of treatment of the
nitrogen compounds (The Nitrates Directives
91/676/EEC) in the wastewater that obey to biological
treatment (Morsy et al., 2020). The presented study
reveals how the monitoring of the water quality of the
surface watercourses across the municipality of
Kumanovo.
