Pencemaran akibat dari minyak buangan yang terkandung dalam air sisa merupakan salah satu masalah persekitaran yang amat serius. Disebabkan oleh perkembangan industri kelapa sawit yang amat pesat di Malaysia, suatu isipadu air sisa dari kilang kelapa sawit (POME) yang banyak juga dihasilkan pada masa yang sama. Pengekstrakkan minyak buangan dari POME telah dijalankan menggunakan proses pengektrakan pelarut. Dalam kajian ini, kesan masa pengektrakan, nisbah pelarut/suapan dan kadar pencampuran pengektrakan menggunakan beberapa jenis pelarut telah dijalankan. N–pentana, n–hexana dan n–heptana telah digunakan sebagai pelarut. Peratus minyak yang diekstrakkan pada keadaan–keadaan optimum ujikaji menggunakan n–pentana, n–hexana dan n–heptana diperolehi masing–masing sebanyak 58, 63 dan 65 peratus. Pengekstrakan berbagai peringkat juga telah dijalankan. Lebih dari 97% minyak buangan yang terkandung dalam POME telah berjaya diekstrakkan pada peringkat keempat pengekstrakkan menggunakan pelarut–pelarut tersebut. Kata kunci: Pengekstrakkan; kadar pencampuran; masa pencampuran; pelarut; POME Pollution from residual oil content in the wastewater is one of the serious environmental problems. Due to the rapid development of the palm oil industry in Malaysia, a large volume of palm oil mill effluent (POME) has been produced at the same time. Removal of residual oil from POME was carried out using solvent extraction process. The effect of different solvents, extraction time, solvent/feed ratio and mixing rate on extraction efficiency were investigated throughout this work. N– pentane, n–hexane and n–heptane were used as solvents. The percent of oil extracted at the optimum conditions of 10 min extraction time, 1:1 solvent: feed ratio, 200 rpm using n–pentane, n–hexane and n–heptane were found to be 58, 63 and 65, respectively for a single stage extraction. Multistage extraction has shown that the % of oil extracted increased significantly to more than 97% of the residual oil in the POME. Key words: Extraction; mixing rate; mixing time; solvent; POME

Pre Treatment

The global pandemic spread of influenza like bird flu and swine flu are forcing abigger production of anti-influenza drug called Oseltamivir phosphate. The drug is made by synthesizing a compound named shikimic acid. Although the demand of the drug increases, the source of shikimic acid material is limited. Meanwhile, palm oil mill effluent (POME), a waste generated from palm oil industry is provenly rich in phytonutrients. This research aims to improve the shikimic extraction process from palm oil mill effluent by pre-treating the POME. Three pre-treatments were done on the POME which are solvent-extraction method, sedimentation method, and combination of solvent-extraction and sedimentation method. Sedimentation used the centrifugal principle and solvent-extraction used n-hexane as the solvent. Extraction of shikimic acid from pre-treated POME was done using ethyl acetate as the solvent. Detection of shikimic acid was done using TLC method and FT-IR instrument, while HPLC was used to measure the amount of shikimic acid extracted. Yield of shikimic acid obtained after solvent-extraction pre-treatment (0.0795%) was better than the sedimentation pre-treatment (0.015%). Also, the solvent-extraction pre-treatment was more efficient (87.51%) than sedimentation pre-treatment (68.15%) in removing oil and grease. However, the best result was produced from the combination of both pre-treatments.

Suspended solids and residual oil removal in a liquid are relevant to numerous research areas and industry. The suspended solid cannot be removed completely by plain settling. Large and heavy particles can settle out readily, but smaller and lighter particles settle very slowly or in some cases do not settle at all. Because of this, it requires efficient physical-chemical pretreatment methods.   Our current research is to study the pretreatment methods in the removal of suspended solids and residual oil content in POME. Preliminary analysis shows that POME contains 40,000 mg/L suspended solid and 4,000 mg/L oil and grease content that relatively very high compared to the maximum allowable limit by the Malaysian Department of Environment which are only 400 mg/L and 50 mg/L respectively. The methods chosen were coagulation-sedimentation method for suspended solids removal and solvent extraction for residual oil removal.  Jar test apparatus was used as the standard procedure for bench-scale testing and alum was used as the coagulant. Parameters studied were alum dosage, mixing time, mixing speed, sedimentation time and pH. For removal of residual oil, six different organic solvents; n-hexane, n-heptane, benzene, petroleum ether, pentane and petroleum benzene were used. For every solvent the effect of solvent ratio, mixing time, mixing speed and pH were analyzed. The results show that the optimum conditions in removal of suspended solid from POME were at pH 4.11, sedimentation time of 100 minutes and 150 rpm mixing speed with 1.5 hr mixing time. N-hexane give the best performance in extracting residual oil from POME with solvent to POME ratio of 6:10. It was estimated about 0.54 grams of oil and grease can be extracted with optimum variables at pH 4, mixing speed of 200 rpm, and 20 minutes mixing time.  Key Words: palm oil mill effluent, coagulation, suspended solid, residual oil, solvent extraction.

Palm oil industry in Malaysia has grown to become an important agriculture based industry and it is accounted for about 52% of the world palm oil output, which generated RM 13 billions export earning for the country.  With increased cultivation and production of palm oil in the region, the disposal of the processed waste will become a major problem if it is not being treated properly.  Palm oil mill effluent (POME) is extremely polluting with its high organic content. Oil and grease content in POME is 4,000 mg/L which is relatively high compared to the allowable limit by the Malaysian Department of Environment of only 50 mg/L.  This paper describes the research results in removing oil and grease content for the POME using solvent extraction method.  Six different organic solvents; n-hexane, n-heptane, benzene, petroleum ether, pentane and petroleum benzene were used.  For every solvent the effect of solvent ratio, mixing time, mixing speed and pH were analyzed to determine the optimum condition for maximum extraction of oil.  Results showed that n-hexane give the best performance in extracting oil from POME with solvent to POME ratio of 6:10.  It was estimated about 0.54 grams of oil and grease per liter of POME can be extracted at optimum conditions; mixing speed of 200 rpm, 20 minutes mixing time and at pH 9.

In this study, a novel adsorbent was prepared, namely alginate and mangrove composite beads coated with chitosan (AMCBCC), and performed well to remove heavy metals and residual oil from palm oil mill effluent (POME) using continuous adsorption studies in a fixed bed column under different bed heights. Thomas and Yoon–Nelson models were applied to predict the breakthrough curve and to compute the characteristic parameters such as maximum capacity and the time required for 50% of adsorbate breakthrough. It was found that the total removal percentage of iron ions, zinc ions, and residual oil were 26.75%, 76.74%, and 83% respectively at pH 3, and a bed height 27 cm. Both models can well describe the breakthrough curve of heavy metals and residual oil. These results indicated that AMCBCC can be used to remove heavy metals and residual oil from industrial wastewater. ABSTRAK: Kajian ini menyediakan tentang penjerap baharu iaitu alginat dan manik komposit bakau bersalut kitosan (AMCBCC), berfungsi menyingkirkan logam berat dan sisa minyak daripada efluen kilang minyak sawit (POME) dengan sempurna, menggunakan kajian penjerapan berterusan dalam lapisan lajur tetap pada ketinggian berbeza. Model Thomas dan Yoon-Nelson telah digunakan bagi meramal lengkungan terbaik dan mengira parameter cirian seperti keupayaan maksimum dan tempoh diperlukan bagi 50% lengkungan terbaik penjerap. Jumlah peratusan penyingkiran ion besi, ion zink, dan sisa minyak masing-masing sebanyak 26.75%, 76.74%, dan  83% pada pH 3, dan pada ketinggian lapisan 27 cm. Kedua-dua model mampu menggambarkan lengkungan terbaik bagi logam berat dan sisa minyak dengan sempurna. Dapatan ini menunjukkan AMCBCC sesuai digunakan bagi menyingkirkan logam berat dan sisa minyak daripada air sisa industri.
