Catalysts, Journal Year: 2021, Volume and Issue: 11(7), P. 782 - 782

Published: June 27, 2021

The petroleum industry is one of the most rapidly developing industries and projected to grow faster in coming years. recent environmental activities global requirements for cleaner methods are pushing refining use green techniques industrial wastewater treatment. Petroleum contains a broad diversity contaminants such as hydrocarbons, oil grease, phenol, ammonia, sulfides, other organic composites, etc. All these compounds within discharged water from exist an extremely complicated form, which unsafe environment. Conventional treatment systems treating refinery have shown major drawbacks including low efficiency, high capital operating cost, sensitivity biodegradability toxicity. advanced oxidation process (AOP) method applied objective this work review current application AOP technologies wastewater. using includes Fenton photo-Fenton, H2O2/UV, photocatalysis, ozonation, biological processes. This reports that efficiencies strongly depend on chosen type, physical chemical properties target contaminants, conditions. It reported mechanisms, well hydroxyl radical oxidation, might occur throughout donate decrease contaminants. Mainly, advances discussed. Moreover, identifies scientific literature knowledge gaps, future research ways provided assess effects

The application of photoelectrocatalysis in the degradation of rhodamine B in aqueous solutions: a review

RSC Advances, Journal Year: 2022, Volume and Issue: 12(40), P. 26176 - 26191

Published: Jan. 1, 2022

The pollution of the water environment by industrial effluents is an ongoing challenge due to rate industrialisation and globalisation. Photoelectrocatalysis (PEC), electrochemical advanced oxidation process, has proven be effective method for removing organics from wastewater. environmentally benign, cost-effective easy operate. In this present review, we examine recent progress in removal rhodamine B dye, a common constituent textile effluent released into environment, through photoelectrocatalytic degradation. We detailed discussion on use different kinds unmodified modified photoanodes that have been explored dye. More importantly, discussions are presented mechanisms kinetics degradation dye using these photoanodes. Hence, review will beneficial researchers developing future projects area wastewater treatments photoelectrocatalysis.

Wastewater treatment: A short assessment on available techniques

Alexandria Engineering Journal, Journal Year: 2023, Volume and Issue: 76, P. 505 - 516

Published: June 22, 2023

Over the past few decades, there has been a significant increase in population and unsustainable urbanization, resulting exploitation of water energy resources on large scale. This led to rise demand for freshwater, which, turn, caused pollution due improper disposal wastewater from various sources such as industries, agriculture, households. The industries often contains toxic heavy metals harmful emerging contaminants (ECs), which can harm living beings cannot biodegrade. Hence, it is severe issue that needs be addressed. To combat this problem, treatments are necessary two main reasons: firstly, recycle reuse meet future human reduce scarcity, secondly, ensure compliance with discharge standards environmental sustainability while minimizing groundwater soil contamination. In review, several treatment technologies comprising physical, chemical, biological methods have discussed critically. state-of-the-art discussion different existing techniques their limitations deliberated. Finally, contemporary trends highlighted.

Abstract In this study, we have touched on two goals of sustainable development, namely, the provision clean water and sanitation energy at acceptable prices, hoping for good health all ages. A green economical method was used to prepare silver nanoparticles from chitosan biopolymer. AgNPs were fully characterized using UV–Vis, FTIR, XRD, HR-TEM, EDX analysis. Different concentrations (0.02–0.18 g/L) integrated into a mixture heterogeneous nano photocatalysts TiO 2 ZnO (1:1 weight ratio) under UV irradiation photocatalytic degradation Acid Red 37 textile dye obtain water. The kinetic description performed process presented assuming pseudo-first-order reaction. data revealed that increasing concentration in catalytic showed high apparent rate constant (k app ) accompanied by an increase quantum yield (%Q ), followed destruction after very short time (t 0.5 = 3 min). Since consumes electrical energy, per order (EE/O) calculated, showing low value 20 kWh/m /order, 0.18 g/L AgNPs, indicating elicited is one mineralization targeted dye.
