PENGOLAHAN LIMBAH BATIK MENGGUNAKAN MEMBRAN ZEOLIT NANOFILTRASI ALIRAN CROSS-FLOW UNTUK FILTRASI KEKERUHAN WARNA DAN AMONIUM

ABSTRAK

Berkembangnya industri batik sejak ditetapkannya Hari Batik Nasional pada tanggal 2 Oktober 2009 lalu semakin meningkatkan jumlah produksi batik di Indonesia. Munculnya industri-industri batik baru menyebabkan limbah sisa produksi batik semakin banyak dan perlu adanya pengolahan salah satunya dengan membran nanofiltrasi. Membran nanofiltrasi yang terbuat dari batuan zeolit alam yang mudah didapat. Untuk pengujian membran digunakan reaktor aliran cross-flow untuk mengetahui nilai fluks yang dihasilkan oleh membran. Aliran cross-flow dipilih untuk mengurangi resiko fouling atau penyumbatan membran akibat partikel yang menumpuk di membran sehingga kinerja membran menjadi lebih baik. Sedangkan untuk analisis morfologi dan struktur membran digunakan alat Scanning Electron Microscopy SEM. Parameter yang akan diujikan pada penelitian ini adalah kekeruhan warna dan amonium yang terdapat pada limbah cair industri batik. Metode yang digunakan adalah Metode Turbidimetri untuk parameter kekeruhan Metode Spektroforometri untuk parameter warna dan Metode Nessler untuk parameter amonium. Ketiga metode tersebut akan diuji kandungannya sebelum dan setelah di ujikan dalam reaktor cross-flow. Bahan baku zeolit alam yang digerus dan lolos ayakan 200 mesh akan digunakan sebagai bahan baku campuran membran zeolit nanofiltrasi. Dengan variasi massa membran 3 gram dan 5 gram serta variasi konsentrasi air limbah 100 75 dan 50 dihasilkan masing masing nilai yang berbeda untuk setiap parameter. Untuk parameter kekeruhan nilai rejeksi tertinggi yang dihasilkan adalah 9293 membran massa 3 gram untuk konsentrasi 100 9569 dan 9517 untuk konsentrasi masing-masing 75 dan 50 pada massa membran yang sama. Terjadi perbedaan untuk setiap parameter air limbah yang dianalisis. Selain itu pengujian pada reaktor cross-flow dilakukan untuk mengetahui nilai fluks yang dihasilkan membran zeolit nanofiltrasi untuk setiap variasi massa dan konsentrasi limbah. Selain itu dilakukan uji morfologi membran dengan menggunakan SEM EDX untuk mengetahui struktur dan unsur yang terdapat pada membran zeolit


ABSTRACT

The development of batik industry since the enactment of National Batik Day on October 2nd 2009 increasing the amount of production of batik in Indonesia. The emergence of new batik industries causing residual waste which are need for treated. One of the treatment of batik waste is with nanofiltration membrane. Nanofitration membrane made of natural rock named zeolite that easily found and obtained. Then cross-flow reactor is used to determine the rejection percentage and the value of flux flow generated by membrane. Cross-flow reactors chosen to reduce the risk of fouling and clogging due to accumulation of particles in nanofiltration membrane. As for the analysis of structure and morphology of membrane we use Scanning Electron Microscopy SEM. There are some parameters will be tested and determined in this study i. e turbidity color and ammonium. Each parameters use different method to analyze base on the standart method. For turbidity method used is Hellige Turbidimetry methods Spectrometry for color and Nessler for ammonium parameters. All of those three methods will be tested before and after cross-flow reactor examination. The natural zeolite rock will be sieved until 200 mesh and will be used as the mixture and raw material of nanofiltration membrane. With the variation of mass of 3 grams and 5 grams membrane as well as the concentration of batik wastewater with raw water about 100 75 and 50 ratio of batik wastewater and raw water respectively produced different values of each parameters. For turbidity parameters the highest rejection value is 9293 for the 3 grams membrane and 100 concentration of batik waste and respectively 9569 and 9517 for each 75 and 50 concentration of batik waste in the same mass of membrane. And there are some difference with other parameters value. In addition examination of cross-flow reactor used to determine the value of generated flux in every mass and concentration variation of membrane and SEM EDX to determine the structure and elements contained in zeolite nanofiltration membrane.
