The parameters affecting treatment effciency of pistachio processing industry waste waters was
investigated by continuous electrocoagulation process. Aluminum is used as the anode electrode material in the
electrocoagulation process. Electrochemical reactor made of stainless steel was used as a cathode electrode material.
Experimental studies carried out in continuous mode. The anode electrode used is an electrode which has 5 mm
thick , 60 mm outer diameter , a tubular having 650 mm height. A reactor made of stainless steel with 3 mm wall
thickness, 70 mm internal diameter, 650 mm height is used as cathode electrode. Distance between the electrodes
is chosen as 5 mm. The initial pH value of waste water and waste water flow rate are chosen as the experimental
parameters effecting the removal effciency. In optimum conditions of experimental studies performed by the
electrocoagulation process, COD and total phenol (TF) removal effciencies were obtained respectively 70% and
92%

Antep Fıstığı İşleme Sanayi Atıksularının Sürekli Elektrokoagülasyon Prosesi ile Arıtımına Etki Eden Parametrelerin İncelenmesi

Öz

Antep fıstığı işleme sanayi atıksularının sürekli sistem elektrokoagülasyon prosesiyle arıtım verimini
etkileyen parametreler incelenmiştir. Anot elektrot malzemesi olarak elektrokoagülasyon prosesinde alüminyum
kullanılmıştır. Katot elektrot malzemesi olarak paslanmaz çelikten imal edilmiş elektrokimyasal reaktör kullanılmıştır.
Deneysel çalışmalar sürekli modda gerçekleştirilmiştir. Kullanılan anot elektrot 5 mm et kalınlığında, 60 mm dış
çaplı, 650 mm yüksekliğe sahip boru tipi elektrottur. Katot elektrot olarak 3 mm et kalınlığına, 70 mm iç
çapa, 650 mm yüksekliğe sahip paslanmaz çelikten imal edilmiş reaktör kullanılmıştır. Elektrotlar arası mesafe
5 mm olarak seçilmiştir. Giderim verimine etki eden deneysel parametreler olarak, atıksu başlangıç pH değeri ve
atıksu debisi seçilmiştir. Elektrokoagülasyon prosesi ile yapılan deneysel çalışmaların optimum şartlarında KOİ ve
toplam fenol (TF) giderim verimleri sırasıyla %70 ve %92 olarak elde edilmiştir.
