Performance of cellulose acetate membrane with different additives for palm oil mill effluent (POME) liquid waste treatment

Land application of liquid waste containing palm oil mill effluent (LW-POME) as soil ameliorant can cause water contamination due to its high content of nitrate if improperly treated. Indonesia is rich with volcanic tuff materials that contain variable charged soil clay minerals. This study was aimed at to extract nanoclays (fraction sized <200 nm) from volcanic tuffs of Mt. Salak, West Java, Indonesia, and evaluate their potential use as adsorbent of nitrate in LW-POME. By applying dispersion, ultrasonication, centrifugation, and dialysis separation techniques, it could be extracted positively charged nanoclays nc3 and nc4 from the respectively tuff materials tv3 and tv4. Their potential use as natural adsorbent of nitrate as anionic contaminant was evaluated using Langmuir isothermal adsorption model. After 48 h equilibration, it could be extracted 4.33 mg nc3/g tv3 and 7.73 mg nc4/g tv4 with nitrate adsorption maxima of 48.3 and 40 mg/g for nc3 and nc4, respectively. The removal of nitrate in the LW-POME from 62 to 20 mg/L as to comply with the Indonesian liquid waste quality standard required 29.81 mg nc3/L or 39.34 mg nc4/L. The extracted nanoclays were considered prospective to be utilized as natural adsorbent for nitrate removal in LW-POME.

The palm oil industry is one of the major agro-based industries in Malaysia whose production accounts for more than 90% of the world export. The industry, however, also generates enormous quantities of liquid waste with high organic load causing serious pollution problems. In view of the high level of organics, anaerobic pretreatment is usually practised prior to aerobic breakdown. Most of the anaerobic digesters installed at the mills are currently operated under mesophilic conditions. However, the inherently high temperature of the effluent suggests that thermophilic digestion would bring about a much more effective system. This paper reports on results obtained from a pilot plant study on thermophilic anaerobic contact digestion of palm oil mill effluent which has been conducted and includes a microbiological study associated with the investigation.

ABSTRAKEnergi memiliki peranan penting dalam proses pembangunan yang pada akhirnya untuk mencapai tujuan sosial, ekonomi dan lingkungan untuk serta merupakan pendukung bagi kegiatan ekonomi nasional. Sumber energi terbarukan yang berasal dari pemanfaatan biogas limbah cair kelapa sawit dapat menghasilkan energi listrik yang saat ini banyak bergantung pada generator diesel dengan biaya yang mahal.Limbah cair kelapa sawit (Palm Oil Mill Effluent atau POME) adalah limbah cair yang berminyak dan tidak beracun, berasal dari proses pengolahan minyak kelapa sawit, namun limbah cair tersebut dapat menyebabkan bencana lingkungan apabila tidak dimanfaatkan dan dibuang di kolam terbuka karena akan melepaskan sejumlah besar gas metana dan gas berbahaya lainnya ke udara yang menyebabkan terjadinya emisi gas rumah kaca. Tingginya kandungan Chemical Oxygen Demand (COD) sebesar 50.000-70.000 mg/l dalam limbah cair kelapa sawit memberikan potensi untuk dapat di konversi menjadi listrik dengan menangkap biogas (gas metana) yang dihasilkan melalui serangkaian tahapan proses pemurnian. Di Kabupaten Kotawaringin Timur terdapat 36 Pabrik Pengolahan Kelapa Sawit yang total kapasitas pabriknya adalah sebesar 2.115 TBS/jam, menghasilkan limbah cair sebesar 1.269 ton limbah cari/jam dan mampu menghasilkan 42.300 m3 biogas.Kata kunci: Renewable Energy, Plam Oil Mill Effluent, Chemical Oxygen Demand, Biogass, Methane. ABSTRACTEnergy has an important role in the development process and ultimately to achieve the objectives of social, economic and environment for as well as an environmental support for national economic activity. Renewable energy source derived from wastewater biogas utilization of oil palm can produce electrical energy which is currently heavily dependent on diesel generators at a cost that mahal.Limbah liquid palm oil (Palm Oil Mill Effluent, or POME) is the wastewater that is greasy and non-toxic, derived from the processing of palm oil, but the liquid waste could cause environmental disaster if not used and disposed of in open ponds because it will release large amounts of methane and other harmful gases into the air that cause greenhouse gas emissions. The high content of Chemical Oxygen Demand (COD) of 50000-70000 mg / l in the liquid waste palm oil provides the potential to be converted into electricity by capturing the biogas (methane gas) produced through a series of stages of the purification process. In East Kotawaringin there are 36 palm oil processing factory that total factory capacity is of 2,115 TBS / hour, producing 1,269 tons of liquid waste wastewater / h and is capable of producing 42,300 m3 of biogas.Keywords: Renewable Energy, Plam Oil Mill Effluent, Chemical Oxygen Demand, Biogass, MethaneCara sitasi: Alkusma, Y.M., Hermawan, dan Hadiyanto.

Industri minyak sawit mempunyai impak yang besar ke atas alam sekitar. Efluen kilang minyak sawit (dikenali juga sebagai palm oil mill effluent, POME) merupakan buangan cecair yang terdiri daripada sebatian organik yang berasal daripada bahan bolehurai dan sedia direput oleh miroorganisma aerobik dan juga anarobik. Teknologi rawatan POME masa kini banyak bertumpu kepada kaedah biologis. Proses–proses ini memerlukan keluasan tanah yang besar dan tidak menjamin pencapaian had discas yang dibenarkan[1]. Kertas ini menghuraikan satu kajian mengenai potensi kegunaan teknologi membran untuk merawat POME dari kolam discas terakhir. Bahagian pertama kajian ini meneliti ciri–ciri beberapa kolam yang terdapat di loji rawatan air sisa POME yang sedia ada. Kajian membran pula melibatkan penggunaan membran gentian kosong dengan MWCO berjulat 30K hingga 100K. Data yang diperolehi menunjukkan bahawa membran yang mempunyai MWCO 100K menghasilkan fluks yang lebih tinggi daripada membran MWCO 30K, tetapi membran MWCO 30K memberi permeat yang kualitinya lebih baik. Kualiti permeat hasil daripada membran di atas berjaya menurunkan COD, SS, TKN dan nitrogen–amonia masing–masing sebanyak 97.66%, 98%, 53.85% dan 61.91%. Tetapi pemindahan warna memerlukan rawatan tambahan. Kata kunci: Membran, penurasan-ultra, POME, rawatan sisa The palm oil industry has a significant impact on the environment. Palm oil mill effluent (POME), which is the liquid discharge, comprises of mainly organic compounds originating from biodegradable materials and is readily decomposed by anaerobic, and aerobic microorganisms. The current treatment technology of POME is largely biological in nature. These processes require large acreage of land and do not always achieve the discharge limits [1]. This paper describes a study on the potential use of membrane technology to treat POME from the final discharge pond. The first part of the study investigated the establishment of characteristics of the various ponds within the current POME wastewater treatment plant. The membrane study essentially used hollow fiber membrane of MWCO ranging from 30 to 100K. The results showed that the hollow fiber membrane with MWCO 100K gave higher fluxes compared to the MWCO 30K, however, the latter membrane gave better quality permeate. The quality of permeate achieved from the membrane with MWCO 30K gave reductions in COD, SS, TKN and ammoniacal–N of 97.66 %, 98 %, 53.85 % and 61.91 % respectively. However, color removal may require further treatment. Key words: Membrane, ultrfiltration, POME, waste treatment

Palm Oil Mill

The palm oil industry produces liquid waste called POME (palm oil mill effluent). POME is stated as one of the wastes that are difficult to handle because of its large production and ineffective treatment. It will disturb the ecosystem with a high organic matter content if the waste is disposed directly into the environment. The authorities have established policies and regulations in the POME waste quality standard before being discharged into the environment. However, at this time, there are still many factories in Indonesia that have not been able to meet the standard of POME waste disposal with the existing treatment technology. Currently, the POME treatment system is still using a conventional system known as an open pond system. Although this process can reduce pollutants’ concentration, it will produce much sludge, requiring a large pond area and a long processing time. To overcome the inability of the conventional system to process POME is believed to be a challenge. Extensive effort is being invested in developing alternative technologies for the POME waste treatment to reduce POME waste safely. Several technologies have been studied, such as anaerobic processes, membrane technology, advanced oxidation processes (AOPs), membrane technology, adsorption, steam reforming, and coagulation. Among other things, an AOP, namely photocatalytic technology, has the potential to treat POME waste. This paper provides information on the feasibility of photocatalytic technology for treating POME waste. Although there are some challenges in this technology’s large-scale application, this paper proposes several strategies and directions to overcome these challenges.

ABSTRACT The green revolution in the field of palm oil farming not only contributes to processed products but also produces large-capacity waste originating from its processing starting from the sterilization process, water from the clarification process, hydro cyclone (clay bath) water, and factory washing water. Palm oil mill effluent (LCPKS) contains dissolved and suspended solids in the form of colloids and oil residues with high BOD and COD. If this liquid waste is discharged directly into the water, it can pollute the environment. Some will settle, decompose slowly, consume dissolved dcxdcoxygen, cause turbidity, emit a sharp odor and can damage the aquatic ecosystem. To improve the parameters in the LCPKS so that it is feasible to flow to water bodies or the environment, an LCPKS treatment experiment test is performed by applying corona discharge with variations in voltage and length of time, then comparing the effect on parameters such as BOD, COD, pH and TDS on LCPKS before treatment and after treatment. From the treatment process using a corona discharge application with variations in voltage and time able to reduce BOD levels up to 35%, COD 36%, increase in TDS reached 71.56% and decreased pH by 4.11%.Key words: Palm oil mill effluent (LCPKS), Corona discharge application (Corona Discharge Treatment), COD, BOD, TDS, pH

Oil palm plantations of PT. Supra Matra Abadi has used palm oil mill effluent to the plantation area as fertilizer (Land Application) to part of its plantation area. The difference in land use and management in the plantation area also determines the presence, both species, density, diversity index value, and soil macrofauna uniformity index. Soil macrofauna plays a role in maintaining the balance of the soil ecosystem. This research has been conducted at PT. Supra Matra Abadi, located in Kebun Panji Bay, Kampung Rakyat District, Labuhanbatu Selatan Regency, North Sumatra Province in May-July 2018. This research was conducted to determine the presence of species, population density, diversity index values, and uniformity of soil macrofauna on oil palm plantations. Determination of the sampling point is done by the Purposive Random Sampling method, soil macrofauna sampling using the Quadratic and Hand Sorting methods. There are 15 species of soil macrofauna which are grouped into 2 phyla, 5 classes, 9 orders, 12 families, and 15 genera. The highest density value was found in the area of plantations that were not given liquid palm oil mill effluent as fertilizer (Non Land Application) of 282.15 ind / m2 and the highest diversity index value was found in the area of oil palm plantations which were fertilized with palm oil mill liquid waste to land area (Land Application) which shows that the condition of the oil palm plantation ecosystem which is fertilized with palm oil mill effluent (Land Application) can support the life, diversity, and uniformity of soil macrofauna.

Anaerobic System

ABSTRACTPalm Oil Mill wastewater or POME is currently not fully utilized. POME waste treatment generally uses covered lagoon technology using the anaerobic system, which generally operates well in neutral waste conditions with a pH of 7 and uses mesophilic processes at temperatures around 35oC. So it is necessary to cool down and neutralize before POME is fed to the reactor, by mixing it with POME which has been degraded inside the reactor, where the pH condition has to turn into a base. It is useful to ensure that the POME temperature before being fed into the reactor is near the ambient temperature and the acidity of POME is near neutral (pH = 7). POME treatment using a covered lagoon reactor usually need 30 days residence time. The Fixed Bed anaerobic reactor is capable to treat waste with a low pH waste, so POME which has a pH of 4 does not need to be neutralized before treating using Fixed Bed Reactor. This will simplify the processing process, reduce investment costs and operating costs. The purpose of this research is to process POME waste using an anaerobic type Fixed Bed reactor without neutralization stage. The method processing using Fixed Bed type reactor is divided into two stages of a process that is bacteria inoculation process and POME waste adaptation process. The results of the research can reduce the HRT to 2o days, with optimal POME feeding at 150 liters/day. The percentage of methane gas measured was 66%. The methane gas yield is 0.52 liters/gram of COD or greater than the results of using the covered lagoon, which is 0.35 liters/ gram COD.Key word: Palm Oil Mill Effluent (POME), anaerobic, Fixed Bed, biogas, neutralizationABSTRAKLimbah cair industri minyak kelapa sawit atau POME saat ini belum dimanfaatkan secara maksimal. Pengolahan limbah POME umumnya menggunakan teknologi covered lagoon dengan sistem anaerobik, dimana umumnya teknologi ini beroperasi baik pada kondisi limbah yang netral dengan pH 7 dan menggunakan proses mesopilik pada suhu sekitar 35oC. Sehingga diperlukan tahap pendinginan dan tahap netralisasi terlebih dahulu sebelum POME diumpankan ke reaktor, yaitu dengan mencampurkannya dengan POME yang sudah terdegradasi di dalam reaktor, karena sifatnya sudah berubah menjadi basa. Hal ini berguna untuk memastikan bahwa suhu POME sebelum masuk reaktor sudah mendekati suhu lingkungan dan tingkat keasaman POME sudah mendekati netral (pH =7). Pengolahan POME menggunakan covered lagoon umumnya memerlukan waktu tinggal di dalam reaktor(HRT) sekitar 30 hari. Reaktor anaerobik tipe Fixed Bed mampu mengolah limbah dengan pH rendah, sehingga POME yang mempunyai pH 4, tidak perlu dinetralkan terlebih dahulu. Hal ini akan menyederhanakan proses pengolahan, menurunkan biaya investasi dan biaya operasi. Tujuan penelitian ini adalah mengolah limbah POME dengan menggunakan reaktor anaerobik tipe Fixed Bed tanpa tahap proses netralisasi. Metode pengolahan anaerobik dengan menggunakan reaktor tipe Fixed Bed, terbagi menjadi dua tahapan proses yaitu proses inokulasi bakteri dan proses adaptasi limbah POME. Hasil penelitian dapat menurunkan HRT menjadi 20 hari, dengan pengumpanan POME optimal pada 150 liter/hari. Persentase gas metana adalah 66%. Hasil produksi gas metana adalah 0,52 liter/gram COD atau lebih besar dari hasil proses menggunakan covered lagoon, yaitu 0,35 liter/ gram COD.Kata Kunci: Palm Oil Mill Effluent (POME), anaerobik, Fixed Bed, biogas, netralisasi

The objective of this research is to investigate the performance of blend cellulose acetate (CA)–polyethersulphone (PES) membranes prepared using microwave heating (MWH) techniques and then compare it with blend CA-PES membranes prepared using conventional heating (CH) methods using bovine serum albumin solution. The superior membranes were then used in the treatment of palm oil mill effluent (POME). Various blends of CA-PES have been blended with PES in the range of 1–5 wt%. This distinctive series of dope formulations of blend CA/PES and pure CA was prepared using N, N-dimethylformamide (DMF) as solvent. The dope solution was prepared by MW heating for 5 min at a high pulse and the membranes were prepared by phase inversion method. The performances of these membranes were evaluated in terms of pure water and permeate flux, percentage removal of total suspended solids (TSS), chemical oxygen demand (COD) and biochemical oxygen demand (BOD). The results indicate that blend membranes prepared using the microwave technique is far more superior compared to that prepared using CH. Blend membranes with 19% CA, 1–3% PES and 80% of DMF solvent were found to be the best membrane formulation.
