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.
