Wastewater Treatment Plants (WWTPs) encompass a range of processes from preliminary to advanced stages. Conventional treatments are increasingly inadequate for handling emergent pollutants, particularly organic compounds with carcinogenic potential that pose risks aquifers. Recent advancements prioritize integrating Advanced Oxidation Processes (AOPs) and adsorbents conventional methods effectively retain pollutants enhance mineralization. There is growing preference non-chemical or minimally chemical approaches. Innovations such as combining ozone other biological photo-sono-assisted methods, alongside AOPs adsorbents, promising. These approaches leverage catalyst-assisted reactions optimize oxidation efficiency. This review aims provide holistic perspective on WWTP processes, spanning wastewater intake the production potable water, highlighting key technologies, operational challenges, future trends. The focus advancing sustainable practices enhancing treatment efficacy safeguard water quality address evolving environmental concerns effectively.

The increasing presence of various organics poses significant threats to aquatic ecosystems and living organisms. Conventional water treatment methods are often insufficient, necessitating the development powerful sustainable alternatives. This study addresses this challenge by exploring synthesis ZnO nanoparticles using green tea leaves extract-an eco-friendly approach-for sunlight-activated removal in agri-food wastewater. research examined different conditions for clomazone (CLO), tembotrione (TEM), ciprofloxacin (CIP), zearalenone (ZEA). Nitrate-derived synthesized a medium (N-gZnOw) exhibited highest photocatalytic activity, removing 98.2, 95.8, 96.2, 96.6% CLO, TEM, CIP, ZEA. Characterization techniques (XRD, Raman spectroscopy, SEM, zeta potential measurements, UV-visible spectroscopy) confirmed N-gZnOw, with an average particle size 14.9 nm, isoelectric point 9.9, band gap energy 2.92 eV. Photocatalytic experiments identified 0.5 mg/cm3 as optimal catalyst loading, while higher initial pollutant concentration reduced degradation efficiency. LC-ESI-MS/MS measurements efficient formation intermediates. Hence, demonstrates that extract-synthesized offer promising, solution herbicides, pharmaceuticals, mycotoxins from wastewater, paving way purification technologies.

This work examined the influence of UV-A light modulation on photocatalytic process coadjuvated with H2O2 to mineralize phenol in an aqueous solution. A fixed-bed batch reactor a flat-plate geometry, irradiated by LEDs, was employed. The successful deposition commercial TiO2 PC105 steel plate (SP) achieved, and structured photocatalyst characterized using Raman spectroscopy, specific surface area (SSA) measurements, UV–vis DRS analysis. These analyses confirmed formation titania coating anatase phase bandgap energy 3.25 eV. Various LED-dimming techniques, both fixed variable duty cycle values, were tested evaluate stability photocatalyst’s activity operating parameters during mineralization 450 mL optimal identified as initial concentration 10 ppm, hydrogen peroxide dosage 0.208 g L−1, triangular modulation. Under these conditions, highest apparent degradation kinetic constant (0.39 min−1) total achieved. Finally, consumption for mineralizing 90% one cubic meter treated water determined, showing greatest savings
