Abstract

Lindi air sampah tempat pemrosesan akhir memiliki kandungan organic biodegradable yang rendah sehingga sulit untuk diproses secara biologis sehingga pengolahan dengan elektrokoagulasi kontinu (CEC) menjadi solusi karena menawarkan banyak manfaat seperti mudah dalam pengoperasi, pemeliharaan alat dan proses yang mudah, dan dapat mengolah banyak macam limbah. Di sisi lain, performansi CEC dipengaruhi oleh berbagai aspek sehingga harus dievaluasi untuk proses pengolahan pada lindi air sampah tersebut. CEC diketahui dapat menyisihkan COD, BOD, TSS, dan Total Nitrogen melalui proses oksidasi pada anoda yang menghasilkan insitu koagulan bersamaan dengan terjadinya reaksi reduksi pada katoda yang menghasilkan mikro bubbles oksigen dan evolusi gas hidrogen. Penelitian ini dilakukan untuk mengetahui pengaruh kerapatan arus, jenis anoda, model katoda dalam proses penyisihan polutan lindi sampah. Eksperimen dilakukan pada skala lapangan. Variabel penelitian yang digunakan, antara lain kerapatan arus (1100, 1250, 1400 A/m2), jenis anoda (Fe dan Mg), dan modal katoda (Single dan Double Helix). Influen dipompa masuk ke reaktor melalui mesin pompa dengan debit 150 L/jam yang sambil diinjeksi dengan udara dengan tekanan 4 bar setiap 10 menit yang kemudian efluen tersebut masuk ke dalam bak sedimentasi dengan volume 150 liter. Pengambilan sampel dilakukan dari overflow bak sedimentasi setiap interval 30 menit. Hasil analisa menunjukkan kerapatan arus dipengaruhi oleh jenis anoda. Mg yang dapat meluruh memiliki performansi yang baik pada kerapatan arus 1100 A/m2, sedangkan Fe pada kerapatan arus 1250 A/m2. Selanjutnya, model katoda Single Helix lebih unggul dibandingkan Double Helix dikarenakan mempermudah transfer ion antara anoda dan katoda. Pada konfigurasi Fe-SH-1250, energi spesifik yang dibutuhkan berkisar 282 Wh·g–1 COD, 3836 Wh·g–1 BOD, 1802 Wh·g–1 TKN. Sementara itu konfigurasi Mg-SH-1100, energi spesifik yang dibutuhkan berkisar 151 Wh·g–1 COD, 2023 Wh·g–1 BOD, 951 Wh·g–1 TKN.

Landfill leachate has a low biodegradable organic content making it difficult to process biologically, so treatment with continuous electrocoagulation (CEC) is a solution because it offers many benefits such as easy operation, easy maintenance of tools and processes, and can treat many kinds of waste. However, the performance of CEC is influenced by various aspects so must be evaluated for the treatment process of the leachate. CEC is known to be able to remove COD, BOD, TSS, and Total Nitrogen through an oxidation process at the anode which produces in-situ coagulants along with a reduction reaction at the cathode which produces oxygen, microbubbles, and the evolution of hydrogen gas. This research objective was conducted to determine the effect of current density, anode type and cathode model in the treatment of leachate. Experiments were carried out on a field scale. The research variables include current density (1100, 1250, 1400 A/m2), anode type (Fe and Mg), and cathode models (Single and Double Helix). The influent was pumped into the reactor through a pumping machine with a debit of 150 L/hour while being injected with air at a pressure of 4 bar every 10 minutes, then the effluent entered the sedimentation tank with a volume of 150 liters. Sampling was carried out from the overflow sedimentation tank every 30 minutes intervals. The analysis results that the current density was influenced by the type of anode. Mg has a higher dissolution rate so that retained good performance at a lower current density of 1100 A/m2 than that of Fe. The latter needs a higher current density of 1250 A/m2 to have a better performance. Furthermore, the Single Helix cathode model is superior to the Double Helix because it facilitates the better transfer of ions between the anode and cathode. In the Fe-SH-1250 configuration, the specific energy obtained was around 282 Wh·g–1 COD, 3836 Wh·g–1 BOD, and 1802 Wh·g-1 TKN. Meanwhile, for the Mg-SH-1100 configuration, the specific energy obtained was around 151 Wh·g–1 COD, 2023 Wh·g–1 BOD, 951 Wh·g–1 TKN.
