Abstract
Workshop di PT Pamapersada Nusantara (PAMA)
menghasilkan limbah B3 berupa lumpur campuran antara
pasir/tanah, air, dan hidrokarbon sebanyak 73 drum/tahun.
Limbah tersebut langsung diserahkan ke pihak ketiga untuk
dikelola lebih lanjut. Pada metode co-composting polutan organik
dapat ditambahkan sebagai ko-substrat. Selama proses
pengomposan berlangsung, polutan tersebut dapat mengalami
biodegradasi. Oleh karena itu dilakukan penelitian yang terkait
dengan penerapan metode co-composting pada proses pengolahan
lumpur berminyak. Penelitian ini bertujuan untuk: (1)
menentukan efisiensi penyisihan polutan minyak dengan metode
co-composting, dan (2) menentukan aplikasi teknologi cocomposting
pada proses pengolahan limbah lumpur berminyak di
lapangan.
Penelitian dilakukan pada skala laboratorium dengan
menerapkan metode co-composting selama 60 hari.Variasi yang
digunakan adalah variasi komposisi lumpur dan sampah, serta
variasi campuran kompos. Variasi komposisi lumpur dan sampah
yang digunakan, yaitu: (1) 85% lumpur : 15% sampah; (2) 70%
lumpur : 30% sampah; (3) 55% lumpur : 45% sampah; dan (4)
50% lumpur : 50% sampah. Variasi komponen bahan baku
kompos yang digunakan adalah sampah basah rumah tangga,
serta campuran sampah basah rumah tangga dan kotoran ternak
dengan perbandingan 60:40. Reaktor yang digunakan sebanyak
22 buah dengan kapasitas 5L. Proses aerobik dilakukan melalui
injeksi udara sebesar 2100 L/jam untuk keseluruhan reaktor.
Proses co-composting yang telah berlangsung selama 60
hari mampu menyisihkan polutan minyak sebesar 72% pada
komposisi 55% lumpur : 45% sampah basah rumah tangga.
Penyisihan polutan minyak sebesar ini terjadi karena adanya
kesalahan penggunaan pelarut dalam proses ekstraksi. Pelarut
yang seharusnya digunakan adalah n-heksana yang bersifat nonpolar.
Aplikasi co-composting di lapangan dapat dilakukan
dengan metode trench atau metode in-vessel menggunakan rotary
drum.
===============================================================================
The workshop of PT Pamapersada Nusantara (PAMA)
generates 73 drums/year of hazardous mixed sludge, which is
composed of sand/soil, water, and hydrocarbons. This waste is
directly given to third party for further treatment. In the cocomposting
method, organic pollutant can be added as a cosubstrate.
During the composting process, the pollutant can be
degraded. Therefore, a research work on the application of cocomposting
method for oily sludge treatment will be
implemented. The objectives of this research are (1) to determine
the oil removal efficiency of the oily sludge using co-composting
method, and (2) to determine the field scale application of cocomposting
technology in oily sludge treatment process.
This research was conducted for 60 days at laboratory
scale using PT PAMA oily sludge as a co-substrate and
residential biodegradable solid waste (BSW). The variables
included sludge-BSW composition, and compost raw materials.
Sludge-BSW composition were varied as the following: (1) 85%
sludge : 15% BSW; (2) 70% sludge : 30% BSW; (3) 55% sludge :
45% BSW; and (4) 50% sludge : 50% BSW. The compost raw
materials were BSW and mixture of BSW and cattle manure of
60:40 ratio. 22 reactors with 5L in capacity were used. The
aerobic process was conducted by 2100 L/hour air injection for
all of the reactors.
The 60 day co-composting process could remove 72%
oil pollutant in the reactor of 55% sludge : 45% residential BSW.
This high removal efficiency value was caused by an error in
using organic solvent during the extraction process. The solvent
should be n-hexane which is non-polar. The field scale
application of co-composting method for oil removal could be
performed by trench or in-vessel methods using rotary drums.
