Treatment of dairy wastewater by electrocoagulation using A-U4G (2017-Al) alloy and pure aluminum as electrode material

The electrocoagulation (EC) process is an efficient and low-cost system for the purification of wastewater. aim this work was to investigate efficiency two types aluminum (Al) electrodes (Al alloy pure Al electrodes) treatment synthetic semi-skimmed milk Turbidity, chemical oxygen demand (COD), concentration species were monitored during experiments. effect various parameters, such as current density type nature electrode examined. results showed that exhibited a higher than electrodes. A quasi-total reduction turbidity removal approximately 58% COD achieved within 24 min at pH 7 14.3 mA cm−2. It also observed performance not affected by state surfaces (polished) under same operating conditions.
