Abstract
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 0,001 μm. 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 6,67 L/m2.jam. Permselektivitas membran
zeolit tertinggi dalam menapis nitrat berada pada ukuran partikel 200 mesh
dengan durasi centrifuge 10 menit dengan nilai 89,26% 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 98,18% pada volume limbah 75%.

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
0,001 μm. 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 L/m2.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.
