Degradation of Phenol via an Advanced Oxidation Process (AOP) with Immobilized Commercial Titanium Dioxide (TiO2) Photocatalysts

Nanomaterials, Год журнала: 2023, Номер 13(7), С. 1249 - 1249

Four commercial titanium dioxide (TiO2) photocatalysts, namely P25, P90, PC105, and PC500, were immobilized onto steel plates using a sol-gel binder investigated for phenol degradation under 365 nm UV-LED irradiation. High-performance liquid chromatography (HPLC) total organic carbon (TOC) analyses performed to study the impact of three types oxygen sources (air, dispersed synthetic air, hydrogen peroxide) on photocatalytic performance. The photocatalyst films stable there significant differences in their best result was obtained with P90/UV/H2O2 system 100% about 70% mineralization within 3 h operating conditions varied, showing that water quality is crucial A wastewater treatment plant developed based lab-scale results costs estimated two cases irradiation: (about 600 EUR/m3) sunlight 60 EUR/m3). data show high potential photocatalysts pollutant advanced oxidation process (AOP) conditions, but still need optimization further reduce costs.

Recent Advancements in the Treatment of Petroleum Refinery Wastewater

Water, Год журнала: 2023, Номер 15(20), С. 3676 - 3676

Опубликована: Окт. 20, 2023

The treatment of petroleum refinery wastewater (PRWW) is great interest in industrial management. This contains a diverse concentration contaminants such as oil and grease, hydrocarbons, phenols, ammonia, sulfides, well other organic inorganic composites. Refinery has been attempted through various processes, including physical, biological, chemical, hybrid methods, which combine two or more techniques. review aims to summarize current research studies involved the using conventional, advanced, integrated Furthermore, it critically highlights efficiencies major limitations each technique prospects for improvements. Several conventional techniques (basically, physicochemical biological processes) are discussed. In this context, advanced oxidation processes (AoPs), especially electrochemical photocatalysis, integrated/hybrid found be effective removing recalcitrant fraction pollutants their inherent mechanisms. These could effectively remove COD phenol concentrations with an average removal efficiency exceeding 90%. Hence, also presents elaborate discussion photocatalytic process one some basic concepts optimize degradation photocatalysts. Finally, brief recommendation presented.

Sustainable treatment of surgical cotton processing effluent through coupled biological and photocatalytic reactors

Environmental Technology, Год журнала: 2025, Номер unknown, С. 1 - 13

Опубликована: Март 31, 2025

The growing demand for surgical cotton in the healthcare sector has led to increased production southern Tamil Nadu, generating effluents that pose environmental risks due their chemical composition. Unlike conventional textile effluents, processing wastewater is distinct its lack of colour additive, but it exhibits high oxygen (COD) and contains significant inorganic pollutants, necessitating tailored treatment strategies. Despite extensive research on wastewater, effective solutions remain underexplored. This bridges this gap by exploring a novel synergic method, algae-bacterial symbiosis combined with photocatalytic degradation real effluent, order ultimately improve removal ability contaminants. general aim was study performance three continuous reactor, biological rector coupled biological-photocatalytic (CBPCR) reactor effluent during 30 days. efficacy measured observing rates nutrient, COD, microbial growth. It concluded CBPCR system successfully removed nitrate, phosphate, ammonia, COD 90%, 87%, 75%, 93% respectively. In particular, fostered vigorous growth both microalgae bacteria, as indicated total chlorophyll concentration 20.1 ± 0.91 mg/L dry cell weight 1.81 0.09 g/L. paper shows feasibility green, sustainable strategy such fills current practice industrial treatment.
