Dairy industry wastewater is characterized by high biochemical oxygen demand (BOD5), chemical oxygen demand (COD), and other pollution load. The purpose of this study was to investigate the effects of the operating parameters such as applied voltage, number of electrodes, and reaction time on a real dairy wastewater in the electrocoagulation process. For this purpose, aluminum electrodes were used in the presence of potassium chloride as electrolytes. It has been shown that the removal efficiency of COD, BOD5, and TSS increased with increasing the applied voltage and the reaction time. The results indicate that electrocoagulation is efficient and able to achieve 98.84% COD removal, 97.95% BOD5removal, 97.75% TSS removal, and >99.9% bacterial indicators at 60 V during 60 min. The experiments demonstrated the effectiveness of electrocoagulation techniques for the treatment of dairy wastewaters. Finally, the results demonstrated the technical feasibility of electrocoagulation process using aluminum electrodes as a reliable technique for removal of pollutants from dairy wastewaters.

Electrocoagulation is an electrochemical technology to treat organic and inorganic wastewater without the use of chemicals so as not to increase the burden of environmental pollution. Electrocoagulation performance is influenced by electrode type, current density and number of electrodes. The purpose of this research is to know the effectiveness of COD and oil grease removal from domestic waste water (grey water) through electrocoagulation process. The experiment was conducted in batch using monopolar electrode configuration, with aluminum electrodes 95,7%. In this research, electric current density 21-104 A/m2, detention time and pH were varied. The optimum condition was obtained at current density of 104 A/m2 for 15 minutes with COD and oil grease removal consecutively are 87.48% and 77.50%. The result of this electrocoagulation process shows COD and oil grease concentration of 15.02 mg/L and 4.20 mg/L are under the standard of Ministry of Environment Decree No. 112 Year 2011 grade 3, to be used for watering plants and flushing the hotel toilet.Keywords: electrocoagulation, aluminum electrode, monopolar, current density, grey waterABSTRAKElektrokoagulasi merupakan teknologi elektrokimia untuk mengolah limbah organik dan anorganik tanpa menggunakanbahan kimia sehingga tidakmenambah bebanpencemaran lingkungan.Kinerja elektrokoagulasi dipengaruhi oleh jenis elektroda,kerapatanarusdan jumlah elektroda.Tujuanpenelitian ini untuk mengetahuiefektifitas penurunan organik (COD) dan minyak lemak dari airbuangan domestik (grey water) melalui proses elektrokoagulasi.

Cadmium is one of the heavy metal found in the wastewater of many industries. The electrocoagulation offers many advantages for the removal of cadmium over other methods. So the removal of cadmium from wastewater by using electrocoagulation was studied to investigate the effect of operating parameters on the removal efficiency. The studied parameters were the initial pH, initial concentration, and applied voltage. The study experiments were conducted in a batch reactor with  with two pairs of aluminum electrodes with dimension  and 2mm in thick with 1.5 cm space between them. The optimum removal was obtained at pH =7, initial concentration = 50 mg/L, and applied voltage = 20 V and it was 90%.

ABSTRAK Salah satu upaya untuk menjaga persediaan air yaitu dengan cara menurunkan parameter air laut agar memenuhi parameter air tawar menggunakan metode elektrokoagulasi. Penelitian ini bertujuan untuk mempelajari pengaruh waktu proses elektrokoagulasi terhadap penurunan TDS, kekeruhan, kadar Cl, dan kadar Fe. Selain itu, untuk mengetahui perbandingan antara elektroda Al dan Fe. Air laut diambil dari Pantai Pelabuhan Ratu. Elektroda yang digunakan adalah Al dan Fe dengan ukuran 15x10 cm2. Tegangan yang digunakan yaitu 5 volt atau rapat arus sebesar 0,137 A/dm2 dengan waktu proses 15, 30, 45, dan 60 menit serta volume bahan bakunya 4 Liter. Penelitian dengan waktu proses 30 menit dan proses pengendapan selama satu hari mampu menurunkan kekeruhan hingga 2,28 NTU (55,07%); TDS hingga 1.010 mg/L (3,71%); kadar Cl hingga 271,98 mg/L (3,52%); dan kadar Fe 0,05 mg/L (40,65%). Proses elektrokoagulasi menggunakan elektroda aluminium lebih baik dibandingkan elektroda besi pada waktu proses 30 menit.   ABSTRACT One of the efforts to maintain water supply is by lowering seawater parameters to meet freshwater parameters using the electrocoagulation method.
