Assessing the impacts of wastewater treatment implementation on the water quality of a small urban river over the past 40 years Vrije Universiteit Brussel KU Leuven
This paper studies the effects of the implementation of wastewater treatment (WWT) on the water quality of small urban river systems by considering as an extreme case study (volumetric contribution of wastewaters > 50%) the evolution of the Zenne River waters (Belgium) over the last 40 years. In urban rivers, organic matter (OM), oxygen and nutrients are primarily controlled by wastewater releases which depend on the population and the WWT ...
