Treatment of hospital wastewater by anodic oxidation using a new approach made by combining rotation with pulsed electric current on Cu-SnO2–Sb2O5 rotating cylinder anode

Heliyon, Journal Year: 2025, Volume and Issue: 11(2), P. e42069 - e42069

Published: Jan. 1, 2025

A high-efficiency, low-cost Cu-SnO2-Sb2O5 anode was prepared using a novel approach that combines the effects of rotation with pulsed current. The operating variables such as speed (50-250 rpm), current density (5-20 mA/cm2), and electrodepostion time (30-60 min) on morphology activity were investigated. structure examined by SEM, EDS, XRD techniques. results showed higher combined gave better properties in terms oxidation longer service life time. optimum conditions for preparing 10 mA/cm2, 250 rpm, deposition 60 min. has ability to remove methylene blue (MB) an efficiency 99.7 %. It excellent 30 h. Additionally, potential COD from hospital wastewater 85 % applying mA/cm2 120 min at initial pH 3 where energy consumption 2.85 kWh/kg claimed. combining electric offers enhanced degradation extended life, demonstrating industrial-scale treatment.

Sonoactivated Nanomaterials: A potent armament for wastewater treatment

Ultrasonics Sonochemistry, Journal Year: 2023, Volume and Issue: 99, P. 106569 - 106569

Published: Aug. 29, 2023

The world is currently facing a critical issue of water pollution, with wastewater being major contributor. It comes from different types pollutants, including industrial, medical, agricultural, and domestic. Effective treatment requires efficient degradation pollutants carcinogens prior to discharge. Commonly used methods for include filtration, adsorption, biodegradation, advanced oxidation processes, Fenton oxidation, among others.The sonochemical effect refers the decomposition, reduction, other reactions pollutant molecules in upon ultrasound activation, achieving removal. Furthermore, micro-flow generated by ultrasonic waves creates tiny bubbles eddies. This significantly increases contact area exchange speed dissolved oxygen, thereby accelerating degradation. Currently, ultrasonic-assisted technology has emerged as promising approach due its strong ability, simple cheap equipments, minimal secondary pollution. However, use some limitations, such high energy consumption, lengthy time, limited capacity, stringent quality requirements, unstable effects. To address these issues, combination enhanced nanotechnology proposed shown great potential treatment. Such can greatly improve efficiency resulting an improved performance purification. article presents recent progress development sonoactivated nanomaterials disposal. are systematically classified discussed. Potential challenges future prospects this emerging also highlighted.

The Science of The Total Environment, Journal Year: 2024, Volume and Issue: 921, P. 170994 - 170994

Published: Feb. 15, 2024

Proper treatment of hospital wastewater (HWW) is crucial to minimize the long-term effects on human health and aquatic ecosystems. However, majority HWW generated in low middle-income countries (LMICs), discharged without adequate treatment. This systematic review aims fill knowledge gap LMICs by examining efficacy types technologies used.

Compensatory measures to reduce GHGs in wastewater treatment plants in Southern Italy

Journal of Water Process Engineering, Journal Year: 2024, Volume and Issue: 60, P. 105128 - 105128

Published: March 14, 2024

This study evaluates Greenhouse Gas (GHGs) emissions in 183 Wastewater Treatment Plants (WWTPs) located the Apulia region Southern Italy. All WWTPs examined treat municipal wastewater. GHGs from each treatment unit were estimated current situation and compared, for same WWTPs, to those emitted after assuming structural compensatory measures mitigate them. Total estimation have been equal 83 kg CO2eq/PE⋅y 62 upgrade. Some also discussed lower emitted: recirculation of sludge thickened secondary; reduction biogas systems leakage, aerobic digester thickener coverage new system recovery anaerobic generating energy. upgrade considered result electrical energy significant emission especially digestion based WWTPs.

Three-Dimensional Electrosorption for Pharmaceutical Wastewater Management and Sustainable Biochar Regeneration

Molecules, Journal Year: 2025, Volume and Issue: 30(7), P. 1435 - 1435

Published: March 24, 2025

The adsorption capacity of a biochar (BC) obtained from pine wood residues was evaluated for its ability to remove two pharmaceuticals: fluoxetine (FLX) and sulfamethizole (SMZ). material showed promising results in FLX removal, but limited the case SMZ. In order improve these results, BC surface modifications were made by doping with nitrogen, as well using acid, basic electrochemical treatments. A three-dimensional electrosorption treatment proved be most effective, increasing rate 0.45 13.46 mg/g after evaluating different operating conditions, such electrodes used or dosage. Consecutive cycles use performed through desorption electro-regeneration techniques test reuse, it observed that application 25 mA electric field increased useful life material. Finally, effect ionic strength studied, highlighting presence ions did not significantly affect efficiency SMZ although slight increase at high ion concentration, probably due salinization effect.
