Summary
This review synthesises recent developments in wastewater treatment technologies designed to remove emerging contaminants—including pharmaceuticals, personal care products, and other persistent pollutants. The authors evaluate physical (adsorption, filtration), biological (enzymatic degradation, microbial metabolism), chemical (oxidation, photocatalysis), and hybrid approaches, assessing their relative effectiveness and applicability. The work appears positioned to inform wastewater management practice and environmental policy in the context of intensifying water reuse and agricultural nutrient recovery.
Regional applicability
UK water utilities and environmental regulators operate within strict discharge standards (Environmental Permitting Regulations, Water Environment (Water Framework Directive) Regulations) and may adopt advanced treatment techniques reviewed here, particularly for potable reuse or discharge to sensitive waters. The findings are relevant to UK agricultural wastewater management, where treated effluent is often recycled for irrigation or livestock watering.
Key measures
Treatment efficacy for emerging contaminant removal; comparative performance of physical, biological, chemical, and hybrid techniques; removal mechanisms and pathways
Outcomes reported
The study reviewed treatment techniques (physical, biological, chemical, and hybrid methods) for removing emerging contaminants from wastewater. The review synthesised evidence on the efficacy, mechanisms, and comparative performance of different treatment approaches as of 2021.
