In this study, flaxseed mucilage (FSM) has been used as a green coagulant in the pretreatment stage of a combined process for the removal of an anionic surfactant, sodium dodecyl sulfate (SDS). In the post-treatment stage, heterogeneous photo-Fenton-like oxidation using MnFeO nanocatalyst was applied to remove the remained SDS. Using response surface methodological approach, optimum condition in the coagulation process was obtained at pH 7.0, FSM dose of 100 mg L and 30 min. In the photo-Fenton oxidation process, complete SDS removal was achieved using 76 mg of the nanocatalyst, 1.07 mL of HO at 17 min. Application of the combined process on the real wastewater samples indicates that the proposed method can be used effectively for the treatment of industrial effluents containing surfactants.

Microplastics (MPs) are ubiquitous in aquatic environments, threatening the security of aquatic organisms. Identifying the emission node and hot spot of MPs holds significant importance in the pollution control of MPs. Wastewater is widely recognized as sink and source of MPs, while the direct evidence is insufficient.

Wastewater management is one of the main factors that affect drinking water quality. Therefore, the removal of micropollutant from urban wastewaters is receiving an increased attention. This study conducts a comprehensive life cycle assessment (LCA) and life cycle costing of a full-scale ozonation advanced wastewater treatment for micropollutant removal to identify the main impact contributors.

This review explores biochar's potential as a sustainable and cost-effective solution for remediating organic pollutants, particularly polycyclic aromatic hydrocarbons (PAHs) and pesticides, in water. Biochar, a carbon-rich material produced from biomass pyrolysis, has demonstrated adsorption efficiencies exceeding 90% under optimal conditions, depending on the feedstock type, pyrolysis temperature, and functionalization. High surface area (up to 1500 m/g), porosity, and modifiable surface functional groups make biochar effective in adsorbing a wide range of contaminants, including toxic metals, organic pollutants, and nutrients.
