Arsenate removal from groundwater by air-injected EC with al ball anodes: effects of operational parameters

Öz:
Treatment of arsenate from groundwater by electrocoagulation (EC)reactor with air supply unit using Al ball electrodes were studied in thispaper. Influence of some operating variables, for instance, appliedcurrent (0.075-0.3 A), initial pH (5.5-8.5), air flow rate (0-6 L/min), sizeof Al ball electrodes (5-10 mm), and height of electrode in EC reactor(2-8 cm) on the As(V) removal efficiency were evaluated. The As (V)removal efficiency increased with the increment of applied current, airflow, electrode altitude in EC reactor, and EC time while its removalefficiency decreased with the increment of size of Al ball electrodes. Themaximum As(V) removal percentage, minimum operating cost andenergy consumption were found as 98.68 %, 0.609 $/$m^3$ and3.7694 kWh/$m^3$ at pH of 7.5, current density of 0.30 A, size of Al balls of7.5 mm, height of electrode in EC of 5 c†m, and air flow rate of 6 L/min,respectively

Hava akışlı elektrokoagülasyon reaktörü ile yeraltı sularından arsenik (V) giderimine işletme parametrelerinin etkisi

Öz:
Bu çalışmada hava akışlı elektrokoagülasyon (HA-EK) reaktörü kullanılarak yeraltı sularından arsenik (V) giderimi çalışılmıştır. Arsenik (V) giderimi üzerine, uygulana akım (0.075-0.3 A), başlangıç pH’sı (5.5-8.5), hava akış debisi (0-6 L/dk.), Al bilye elektrot boyutu (5-10 mm) ve EK reaktöründe elektrot yüksekliği (2-8 cm) gibi işletme parametrelerinin etkisi incelenmiştir. Arsenik giderimi veriminde artan akım yoğunluğu, hava debisi ve elektrot yüksekliği ile birlikte ciddi bir artış gözlenmiştir. Ancak, arsenik giderim verimi artan Al bilye boyutu ile birlikte azalmıştır. Optimum şartlarda (pH:7.5 akım yoğunluğu: 0.3 A, Al bilye boyutu: 7.5 mm, elektrot yüksekliği: 5 cm, hava akış debisi: 6 L/dk.) en yüksek arsenik giderim verimi %98.68, en düşük işletme maliyeti 0.609 $/$m^3$ ve en düşük enerji tüketimi 3.7694 kWh/$m^3$ olarak hesaplanmıştır
