Micropollutants in Wastewater: Fate and Removal Processes ...
Micropollutants in Wastewater: Fate and Removal Processes ...

The occurrence of micropollutants (MPs) in various streams of municipal ,wastewater, treatment plants (WWTPs), and their fate and removal processes are discussed. The fate of MPs in WWTPs largely depends on adsorption on suspended particulates, primary and secondary sludge and dissolved organic carbon, and removal occurs due to coagulation-flocculation, and biodegradation.

10/12/2020, · Chromium is an extremely toxic metal in the form of Cr(VI) that causes severe environmental and health problems. Therefore, the aim of this study was to remove chromium ions from ,wastewater, by using cost effective and environmentally friendly bio-sorbents; Moringa stenopetala seed powder (MSSP), and banana peel powder (BPP) and to evaluate its adsorption capacities as bio-sorbents.

19/2/2021, · Refractory organic pollutants in tail water of dyeing ,wastewater, treatment have aroused wide concern. Their efficient and cost-effective removal reduced their threat to public health and ecosystem. Herein, a novel short-cut photocatalysis/algal degradation-based hybrid technology was implemented in efficient removal of methylene blue (MB) in simulated tail water using reliable titanium dioxide ...
