The Application of Electro-Coagulation Technique in Reducing Organic Materials in Waste Water of Fish Culture

Abstract

Elektrokoagulasi merupakan salah satu teknik pengolahan secara fisik yang dapat diterapkan untuk mengolah air limbah pemeliharaan ikan. Penelitian eksperimental ini bertujuan untuk menentukan besar tegangan listrik dan waktu yang efektif teknik elektrokoagulasi dalam pengolahan air limbah. Beberapa perlakuan perbedaan besar (6 dan 12V) selama 15, 30, 45, dan 60 menit diterapkan dalam pengujian. Hasil eksperimen menunjukkan adanya perubahan, berupa peningkatan maupun penurunan kualitas air, dari kondisi awal air limbah. Penurunan Chemical Oxygen Demand (COD) terjadi pada tegangan 12V selama 60 menit (82,89%); ortofosfat pada tegangan 12V selama 45 menit (67,49%); kekeruhan pada tegangan 12V selama 60 menit (69,65%); warna pada tegangan 12V selama 60 menit (70,49%); Total Suspended Solid (TSS) pada tegangan 12V selama 15 menit (31,90%); dan Total Dissolved Solid (TDS) pada tegangan 12V selama 60 menit (10,31%). Selanjutnya, peningkatan amonia bebas terjadi pada tegangan 12V selama 15 menit (291,09%); amonium pada tegangan 12V selama 30 menit (8,85%); dan pH pada tegangan 6V selama 60 menit (16%). Perlakuan terbaik untuk mengolah air limbah pemeliharaan ikan adalah perlakuan tegangan 12V selama 30 menit.

Neutralization of Acidity (pH) and Reduction of Total Suspended Solids (TSS) by Solar-Powered Electrocoagulation System

“…Electrocoagulation contact time can increase th e efficiency of pollutant removal [49,65]. Lastly, the 60-minute contact time of electrocoagulation with aluminum electrodes was found to be the most effective in increasing the pH value [66][67][68].…”

Chemical Oxygen Demand (COD) and Total Suspended Solid (TSS) Removal from Rubber Wastewater Factory Using Electrocoagulation Technique

“…Based on the research conducted by Fitri et al (2020) found that the percentage level of removal of COD and TSS levels in the of fishery activities using the electrocoagulation method that is equal to 82.89% and 31.90% which occurs at a voltage of 12 volts within 60 minutes and 15 minutes (Radityani et al, 2020). Then the research conducted by Ni'am et al (2017) showed that the optimum conditions for removal of COD and TSS levels in textile wastewater were obtained at a voltage of 12 volts within 45 minutes with a percentage level of removal of COD and TSS levels of 76% and TSS of 85%.…”
