Abstract

Karakteristik lindi dalam jangka waktu yang panjang menyebabkan lindi harus diolah menggunakan teknologi yang dapat menguraikan kandungan recalcitrant dan xenobiotic. Mengakibatkan dibutuhkan pengolahan lindi yang matang untuk mencapai standar baku mutu dan biaya yang dapat ditekan. Elektrokimia sebegai pre-treatment pengolahan dapat menaikkan rasio biodegrabilitas lindi sebelum lindi diolah ke pengolahan biologis. Elektrokimia bekerja dengan prinsip penguraian polutan menggunakan breakpoint klorinasi. Tujuan penelitian ini untuk mengkaji pengaruh anoda dan kuat arus terhadap penguraian organik dan nitrogen, menentukan kebutuhan energi serta besaran biaya operasional reaktor pada penurunan organik optimum. Penelitian ini menggunakan elektroda dengan variasi kuat arus, anoda non aktif Boron Doped Diamond (BDD) dan Dimensional Stable Anode (DSA) platina dengan luas 24 cm2. Penelitian ini menggunakan metode membran CMI 7000, AMI 7000. Diharapkan dapat menekan biaya operasi proses. Running reaktor yang bekerja secara batch dilakukan dengan debit pengolahan sebesar 2 mL/det dengan volume 5 L selama 12 jam. Kerapatan arus dilakukan pada variasi 33,33 mA/cm2, 29,17 mA/cm2, dan 25 mA/cm2. Nilai optimum degradasi organik berupa Chemical Oxygen Demand (COD) dan ammoniumnitrogen terjadi pada anoda BDD (33,3 mA/cm2). Polutan COD terurai sebesar 82,38% (2.890 mg/L) dan ammonia-nitrogen sebesar 62,28% (147,42 mg/L). BDD mampu menguraikan polutan organik dan ammonium lebih efektif dibanding platina. Kebutuhan energi spesifik optimum penguraian COD sebesar 68 kWh/g COD dengan biaya operasional BDD sebesar Rp 129.422,00/g COD. ============== The characteristics of leachate in the long-operated sanitary landfill further treatment technology that can remove recalcitrant and xenobiotic compounds. Electrochemical treatment is an alternative of pre-treatment that can increase the leachate biodegradability ratio prior to the biological treatment. The electrochemical process works with the principle of breaking down of non biodegradable organic pollutants using the generated strong oxidative agents. The purpose of this study is to examine the effect of anode material and electrical current density on the degradation od organic and nitrogen contaminants. Also the magnitude of operational reactor costs at optimum degradation of organic measurement is discussed. In this study, two anode materials were investigated, i.e., Boron Doped Diamond (BDD) to represent inert anode and platina (Pt) to represent Dimensionally Stable Anode (DSA) with 24 cm2 of effective surface area. The reactor was designed by applying CMI 7000 and AMI 7000 membranes, to improve the removal efficiency , and thus expectes to reduce the operating cots. Reactor was operated at batch compartment with flowrate of 2 run at batch compartment with discharge 2 mL/sec and feed volume of 5 L for 12 hours. In addition, the electrical current density was 33,33 mA/cm2, 29,17 mA/cm2 dan 25 mA/cm2. The optimum value of organic degradation as Chemical Oxygen Demand (COD) and ammonium-nitrogen was achieved at 33,33 mA/cm2. COD was reduced to 82,38% (2.890 mg/L) and ammonium-nitrogen was reduced to 62,28% (147,42 mg/L). BDD was able to be reduced more effective than platinum. The optimum specific energy requirements for organic decomposition was 68 kWh/g COD, with the BDD operating costs was Rp 129.422,00/g COD.
