ABSTRAK

Teknologi pengolahan air yang saat ini menjadi perhatian para ilmuwan adalah teknologi membran. Keunggulan teknologi membran terdapat pada pengoperasiannya yang tidak membutuhkan energi terlalu besar. Teknologi membran tidak melibatkan perubahan fase dan tidak perlu menggunakan energi panas sehingga komponen di dalamnya dapat dipertahankan. Penelitian ini menggunakan zeolit sebagai membran nanofiltrasi yang memiliki ukuran pori 0001 956m. Penelitian ini mengharapkan nilai koefisien rejeksi yang tinggi dan nilai fluks yang stabil dalam proses filtrasi yang lebih lama dengan preparasi membran nanofiltrasi yang optimal. Metode yang digunakan untuk mengurangi dan mengoptimalkan konsentrasi nitrat dan amonium limbah cair tahu adalah dengan membuat ukuran partikel zeolit 40 mesh dan 200 mesh. Durasi proses centrifuge selama 10 menit dan 20 menit dengan penambahan NH4Cl sebagai porogen serta penambahan lapisan pendukung PEG untuk kekuatan membran. Tujuan dari penelitian ini adalah mengidentifikasi proses sintesis serta karakteristik membran nanofiltrasi dengan bahan baku zeolit alam secara spesifik. Selain itu penelitian ini juga mencari efektifitas kinerja zeolit sebagai membran nanofiltrasi untuk menurunkan kadar nitrat dan amonium. Hasil penelitian ini menunjukkan bahwa kinerja membran zeolit nanofiltrasi sangat baik dan efektif dalam menapis nitrat dan amonium. Permeabilitas membran zeolit nanofiltrasi tertinggi berada pada ukuran partikel 200 mesh dengan durasi centrifuge 10 menit pada 667 Lm2.jam. Permselektivitas membran zeolit tertinggi dalam menapis nitrat berada pada ukuran partikel 200 mesh dengan durasi centrifuge 10 menit dengan nilai 8926 pada volume limbah 25.Sementara itu permselektivitas membran zeolit tertinggi dalam menapis amonium berada pada ukuran partikel 40 mesh dengan durasi centrifuge 10 menit dengan nilai 9818 pada volume limbah 75.


ABSTRACT

Water treatment technologies that are currently of concern to the scientists is a membrane technology. The advantages of membrane technology found in the operation of wastewater treatment that does not require too much energy because it does not involve a phase change energy use and not too hot so that the components inside can be maintained . This research used zeolite as a nanofiltrate membrane with its pore diameter of 0001 956m. This research expects high value of rejection coefficient and stable value of flux on longer filtration process with optimal preparation of nanofiltration membrane. The method which used in order to reduce and optimize concentration of nitrate and ammonium in tofu wastewater was making zeolite particle size 40 mesh and 20 mesh. Duration of centrifuge process as long as 10 minutes and 20 minutes with addition of NH4Cl as a porogent and also addition of supporting layer PEG for membrane strength. The aims of this research were identifying synthesis process and also specific characteristics of nanofiltration membrane with raw material of natural zeolite. Furthermore this research was also finding the effectiveness of zeolite performance as nanofiltration membrane in order to reduce nitrate and ammonium concentrations. This research result shows that the performance of nanofiltration zeolite membrane is very good and effective in filtrating nitrate and ammonium. The permeability of nanofiltration zeolite membrane has its highest value on 200 mesh particle size with 10 minutes centrifuge duration and 6.67 Lm2.hour. The zeolite membrane permselectivity in filtrating nitrate has its highest value on 200 mesh particle size with 10 minutes centrifuge duration and 89.26 effectiveness on 25 wastewater volume. While the zeolite membrane permselectivity in filtrating ammonium has its highest value on 40 mesh particle size with 10 minutes centrifuge duration and 98.18 effectiveness on 75 wastewater volume.
