Electrochemical Treatment of Effluent for the Removal of Contaminants of Emergent Concern and Culturable Microorganisms

The present work aims to study the electrochemical (EC) process applied for removal of contaminants emergent concern (CECs) from wastewater after secondary treatment and effect on total culturable microorganisms. EC experiments were performed in a cylindrical open reactor with 500 mL effluent, fixed current density 8 mA/cm² was through mixed metal oxide electrodes. conducted different sets. In first round (Set 1), effluent sample spiked three CECs (200 ppb each): caffeine (CAF), carbamazepine (CBZ), oxybenzone (OXY). For best period, 6 h, electrodegradation rates ranged 41 ± 7% CAF 95 6% OXY, an 87% second 2), aiming assess efficiency more complex CEC mixture, six diclofenac (DCF), triclosan (TCS), bisphenol A (BPA), 17β-estradiol (E2), 17α-ethinylestradiol (EE2), ibuprofen (IBU), giving nine CECs. this case, allowed decreasing content by 19–100% (below limit detection), depending samples, microorganisms 99.98% h treatment. By contributing degradation microorganism removal, proved be viable remediation disinfection technology plants.
