“…Although hydrophilic fractions have less impact on water quality, but studies show large size molecules of hydrophilic NOM have greatly main contribute to fouling [7]. Many methods have been reported to minimize the fouling such as photocatalytic [8], oxidation and ozonation [9], coagulation-flocculation [10], and adsorption [11]. Among them, adsorption using activated carbon good to removes hydrophilic NOM [12,13].…”

Natural Organic Matter (NOM) content in peat water is a major problem of membrane fouling in ultrafiltration (UF). For that, two stages adsorption as pre-treatment was employed to minimize the membrane fouling of NOM content. This research was carried out to investigate the effect of two stages adsorption on ultrafiltration performance for NOM removal that remains in peat water. This method was using powdered activated carbon (PAC) dosage of 80, 160, 240, 320, 400, 480, 560, 640, 720, 800, 880 dan 960 mg.L-1. Then, Polysulfone (Psf) material was employed for Ultra filtration process. Membrane was applied in a dead-end mode with various operating pressure (1; 1.5; 2; 2.5; 3 bar). As a results, the optimum dose of PAC was 800 mg L-1 with dosage ratio of 3/4:1/4. Two stages adsorption-UF PSf provided the range from 86.9 to 92.8% of KMnO4 and 74.1-88.1% of UV254. For the experimental condition of 3 bar, the highest flux was achieved up to 39.919 L h-1.m-2.

Indonesia memiliki lahan gambut seluas dua puluh juta hektare atau menduduki urutan keempat dalam katagori lahan gambut terluas di dunia setelah Kanada, Uni Soviet, dan Amerika. Lahan gambut tersebut sebagian besar terdapat di empat pulau besar, yaitu Sumatra (35%), Kalimantan (32%), Sulawesi (3%), dan Papua (30%) (Wibowo & Suyatno, 1998). Penyebaran lahan gambut di Sumatra terdapat di dataran rendah sepanjang pantai timur dengan luas 7,2 juta hektare. Riau merupakan provinsi dengan lahan gambut terluas di Pulau Sumatra, yaitu ± 4,04 juta hektare atau 56,1% dari luas total lahan gambut di Sumatra (Wahyunto & Subagjo, 2003).Sementara itu, kebutuhan air bersih semakin meningkat dan persedian sumber air bersih semakin berkurang. Sumber air yang tersedia pada lahan tersebut adalah air gambut yang tidak dapat digunakan secara langsung, baik untuk air bersih atau air minum. Ciri-ciri air gambut adalah air permukaan dari tanah bergambut dengan karakteristik yang sangat mencolok sebagai warna merah kecoklatan (124-850 unit PtCo), mengandung bahan organik tinggi (138-1560 mg/l KMnO 4 ) dan besi yang cukup tinggi, rasa asam, tenaga hidrogen (pH) sekitar 4-7, dan kekerasan yang rendah (Mu'min, 2002), sehingga tidak layak dikonsumsi.

Abstract. In this research, UF membrane was prepared by blending polysulfone (PSf) in DMAc with the addition of PEG400 and low concentration of acetone as additives. The effect of PSf/PEG400 and polymer/solvent ratio on the performance of PSf membrane was investigated during two hours of peat water filtration. The results showed that the increase of ratio PSF/PEG400 from 1:1 to 1:2.5 improved the membrane hydrophilicity. It was indicated by a decrease of water contact angle from 62 o to 33 o and increased water content in membrane structure from 65 to 74,5%. In addition, the pure water flux also increased up to 200 times. A stable flux is achieved when the ratio PSf/PEG is 1:2 and resulted in 84% rejection of humic acid. The increase of polymer concentration in the membrane solution reduced the pure water flux but increased the rejection of humic acid. Higher polymer concentration in membrane solution reduced fouling tendency towards the membrane surface. It showed that flux decline was reduced from 60% to 40% when the ratio of polymer/solvent concentration was changed from 40/60 to 50/50.
