Khoiroh, Lailatul and Aqilah, Hanin and Supriyono, S.T., M.T. and Dr. Eng. Christina Wahyu Kartikowati, S.T., M.T. (2022) Analisa Mekanisme Fouling Membran Menggunakan Model Hermia dalam Pemisahan FAME (Fatty Acid Methyl Ester) dari Gliserol Dan Metanol. Sarjana thesis, Universitas Brawijaya.
Abstract
Teknologi membran memiliki potensi tinggi dalam proses pemurnian FAME (Fatty Acid Methyl Ester). Namun fouling dalam teknologi membran harus dipertimbangkan karena dapat menyebabkan beberapa kerugian. Penelitian ini menganalisa fouling membran menggunakan model Hermia. Data sekunder yang diperoleh dari penelitian Saleh Jehad berjudul ‘The removal of glycerol and methanol from crude FAME using ultrafiltration’ menggunakan tiga membran berbeda sebagai variable yaitu membran polyacrylonitrile, membran polyethersulfone, dan membran polyvinylidene fluoride. Data fluks simulasi yang dihasilkan menggunakan model Hermia divalidasi menggunakan analisa grafik dengan cara menghitung nilai eror dan uji BNT. Hasil simulasi menggunakan Model Hermia didapatkan nilai konstanta complete pore blocking (k2), partial pore blocking (k1), internal pore blocking (k1,5), dan filtration cake development (k0) pada membran polyacrylonitrile berturut-turut 0.03343, 0.0008116, 0.0005035, dan 0.0000249. Nilai k2, k1, k1,5, dan k0 pada membran polyethersulfone berturut-turut yaitu 0,02432, 0,001058, 0,0007325, dan 0,00005. Sedangkan nilai k2, k1, k1,5, k0 pada membran polyvinylidene fluoride berturut-turut 0,0587, 0,000563, 0,000806, dan 0,0000334. Hasil uji nilai error didapatkan mekanisme fouling yang dominan pada membran polyacrylonitrile yaitu mekanisme complete pore blocking, internal pore blocking, dan filtration cake development. Sementara pada membran polyethersulfone adalah complete pore blocking dan pada membran polyvinylidene fluoride adalah internal pore blocking.
English Abstract
Fouling membran is one of the main problems that can cause some disadvantages. This study aimed to assess the fouling mechanism in the biodiesel purification process. The secondary data used was obtained from Saleh Jehad's research entitled 'The removal of glycerol and methanol from crude FAME using ultrafilration' using three different membranes as variables: polyacrylonitrile membrane, polyethersulfone membrane, and polyvinylidene fluoride membrane. The result of simulation flux data using the Hermia model was validated using graphical analysis by calculating the error value and BNT test. The simulation results obtained constant values for complete pore blocking (k2), partial pore blocking (k1), internal pore blocking (k1,5), and filtration cake development (k0) on polyacrylonitrile membranes, respectively 0.03343, 0.0008116, 0.0005035 , and 0.00000249. The values of k2, k1, k1,5, and k0 on the polyethersulfone membrane were 0.02432, 0.001058, 0.0007325, and 0.00005, respectively. While the values of k2, k1, k1,5, k0 on polyvinylidene fluoride membranes were 0.0587, 0.000563, 0.000806, and 0.00000334, respectively. The results of the error value test found that the dominant fouling mechanism on polyacrylonitrile membranes was complete pore blocking, internal pore blocking, and filtration cake development. Meanwhile, the polyethersulfone membrane was complete pore blocking and the polyvinylidene fluoride membrane was internal pore blocking.
