【 摘 要 】

Electrocoagulation/flotationprocess was applied to treat biodiesel wastewater using aluminium electrodes.Firstly, a literature survey was conducted to choose the process variables andthen, operational parameters including initial pH, electrode distance and reactiontime were tested. Experimental results showed the best parameter that can beused in a factorial design for further studies. The results indicate that electrocoagulation/flotationis very efficient to reduce oil and grease, the effluent was very clear aftertreatment and small amount of sludge was produced.
