ABSTRACT
Epoxidized natural rubber/polyvinyl
chloride/microcrystalline cellulose (ENR/PVC/MCC) composite
membranes were prepared and used to treat palm oil mill effluent (POME).
The loadings of MCC were varied at 0, 5, 10 and 15
w/w%. The increment of MCC loads has intensified the hydroxyl
peak of the membranes in FTIR spectrum, indicating the increase
in membrane hydrophilicity. MCC acted as a pore forming
agent since the ENR/PVC/10% MCC gave
the highest water flux and well-distributed pores. After first treatment of POME,
the levels of chemical oxygen demand (COD), biochemical oxygen demand
(BOD)
and total suspended solid (TSS) were reduced to 99.9%, 70.3%, and
16.9%, respectively. These data showed that ENR/PVC/MCC membrane
has the potential to treat POME.

ABSTRAK
Membran komposit getah asli terepoksida/polivinil
klorida/selulosa mikrohablur (ENR/PVC/MCC)
telah disediakan dan digunakan untuk rawatan efluen kilang minyak
kelapa sawit (POME).
Penambahan MCC telah divariasikan pada 0, 5, 10 dan 15 w/w%. Penambahan
MCC telah meningkatkan puncak hidroksil membran melalui
spektrum FTIR yang menunjukkan peningkatan sifat hidrofilik membran.
MCC juga bertindak sebagai ejen penjanaan liang disebabkan
oleh bacaan ujian fluks air yang paling tinggi dan taburan liang
yang sekata pada membran ENR/PVC/10% MCC.
Selepas rawatan POME yang pertama, tahap permintaan oksigen
kimia (COD), permintaan oksigen biokimia (BOD)
dan jumlah pepejal terampai (TSS) masing-masing telah berkurang
sebanyak 99.9%, 70.3% dan 16.9%. Oleh itu, membran ENR/PVC/MCC didapati
berpotensi untuk merawat POME.
