Abstract This study explores the optimization of iron electrocoagulation for treating laundry greywater, which accounts up to 38% domestic greywater. Characterized by high concentrations surfactants, detergents, and suspended solids, greywater presents complex challenges treatment processes, posing significant environmental health risks. Utilizing response surface methodology (RSM), this research developed a second-order polynomial regression model focused on key operational parameters such as area-to-volume ratio (A/V), current density, electrolysis time, settling time. Optimal conditions were identified: an A/V 30 m 2 /m 3 , density 10 mA/cm duration 50 min, settlement period 12 h. Under these conditions, exceptional outcomes achieved, with turbidity removal reaching 94.26% COD at 99.64%. The exhibited effectiveness removal, R value 94.16%, moderate 75.90%. interaction between time particularly underscored their critical role in system design. Moreover, results highlight potential optimizing adapt daily fluctuations production meet specific household reuse needs, toilet flushing. tailored approach aims maximize contaminant separation coagulant efficiency, balance energy use costs, contribute sustainable water management.

Phenol and its derivatives, commonly found in industrial processes as raw materials, intermediates, or final products, pose a considerable environmental risk due to their toxic nature widespread presence effluents. This article offers an in-depth analysis of operational factors advanced strategies for the aerobic breakdown phenol sequencing batch reactors (SBRs). It highlights several innovative techniques that have been developed enhance efficiency biodegradation SBR systems, including use adsorbents within reaction environment integration hybrid treatment methods. These improvements significantly increased removal strengthened microbial communities' ability withstand high levels, up 1000 mg/L, typically wastewater streams. Additionally, investigates application granulation technology SBRs treatment, showcasing exceptional capability manage sudden spikes concentrations, reaching 2000 mg/L. Systems employing shown boost population's resilience influxes considerably reduce sludge volume index (SVI), thereby enhancing sedimentation aggregates improving overall process.

Clean and green: the multifaceted solution of the electrocoagulation technology in emerging contaminants in wastewater

Deleted Journal, Год журнала: 2025, Номер 2(1)

Опубликована: Июнь 2, 2025

Abstract Emerging contaminants (ECs), such as pharmaceuticals and pesticides, pose a threat to water resources due their ecological health impacts, even at low concentrations. Conventional wastewater treatment struggles with these persistent compounds. This review comprehensively examined electrocoagulation (EC) multifaceted sustainable solution for EC removal. We introduced the challenges of ECs limitations traditional methods before detailing principles advantages EC: high efficiency across diverse ECs, operational ease, reduced chemical use. Comparative analysis highlights EC's superior performance, broader applicability, lower costs, less sludge, aligning management. The further explored environmental benefits (reduced chemicals sludge), renewable energy integration potential, favorable LCA/TEA findings. elucidated combined removal mechanisms (coagulation, adsorption, oxidation) crucial role parameters, supported by case studies technology. Finally, we addressed (electrode maintenance, scalability) ongoing research development, automation), concluding emerging trends potential mainstream technology clean, treatment.
