Investigation and assessment of micropollutants and associated biological effects in wastewater treatment processes

Optimization of micropollutant removal from wastewaters using the PROMETHEE multicriteria decision method

“…The bioaccumulation of these pollutants up the food chain further magnifies their impact, affecting not only aquatic life but also the animals and humans that depend on these water bodies for sustenance. This disruption of aquatic ecosystems * Corresponding author: elhammoudani5@gmail.com can lead to reduced biodiversity and the impairment of the ecological balance and functions of water bodies [4,10,[13][14][15][16][17][18][19]. The potential impact of micropollutants on human health is a growing concern.…”

Transformation Analysis of Carbon and Nitrogen Compounds in Wastewater Treated in a Vertical Biofilter

“…However, it should be emphasised that biological processes cannot completely remove the pollutants flowing into the treatment plant in the raw wastewater stream [Gizgis et al 2006]. Therefore, treated wastewater mainly contains hardly biodegradable carbon compounds expressed as COD and residual amounts of nitrogen compounds [Ma et al 2020, Liang et al 2007]. It is important to note here that Polish legislation does not require the specification of nitrogen forms in treated wastewater and only the total nitrogen form in the treated wastewater is standardised.…”

Assessing behavior and fate of micropollutants during wastewater treatment: Statistical analysis

“…They can come from different types of activities (domestic, industrial, craft, and hospital). These effluents contain various chemicals, some of which are described as micropollutants (MPs), such as polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs) [3], and heavy metals (HMs) because they are present at low concentrations in the range of nanograms to micrograms per liter [4].…”
