Abstract


Dilakukan penelitian mengenai pembuatan membran silika nanofiltrasi untuk mengurangi kekeruhan dan fosfat menggunakan reaktor dengan aliran cross flow dengan variasi massa silika 5, 8, dan 10 gram. Silika didapatkan dari sintesis pasir silika menggunakan metode alkali fussion menggunakan peleburan dengan KOH. Variasi limbah yang digunakan adalah 100% limbah, 50% pengenceran dan 75% pengenceran (25% air limbah) dengan air PDAM. Penelitian ini bertujuan untuk mendapatkan pengaruh massa silika terhadap koefisien rejeksi dan nilai fluks pada setiap variasi membran. Data koefisien rejeksi dan nilai fluks menunjukkan variasi membran terbaik yang selanjutnya akan dianalisa morfologinya dengan metode SEM (Scanning Electron Microscopy) dan analisa gugus fungsi dengan metode FTIR (Fourier Transform Infra Red). Didapatkan koefisien rejeksi terbaik adalah 5 gram 100% limbah dengan nilai rejeksi kekeruhan 91,33%. Rejeksi fosfat 56, 07%. Nilai fluks terbaik didapatkan membran 8 gram 25% air limbah dengan nilai fluks 2,81 L/m2.jam.
