Fiqih Virdiansyah, Wahyu (2021) PENYISIHAN REMAZOL RED MENGGUNAKAN MEMBRAN NANOFILTRASI KOMPOSIT FILM TIPIS POLIAMIDA. Sarjana thesis, Universitas Brawijaya.
Abstract
Industri tekstil menghasilkan limbah cair dengan kandungan zat warna sekitar 40%. Zat warna yang banyak digunakan pada industri tekstil adalah Remazol Red yang berdampak pada terganggunya ekosistem perairan dan kesehatan manusia karena bersifat karsinogenik. Penelitian ini bertujuan untuk mengetahui pengaruh konfigurasi aliran membran dan konsentrasi garam NaCl terhadap kinerja membran dalam penyisihan Remazol red. Membran yang digunakan adalah membran komposit film tipis poliamida yang dibuat dengan mereaksikan 0,1% TMC dan 2% MPD diatas permukaan membran. Karakterisasi membran berdasarkan uji FTIR, menunjukkan terbentuknya poliamida dengan adanya gugus fungsi asam karboksilat (-OH), keton (C=O), dan amida (N=H). Pada penyisihan Remazol Red dengan aliran dead end permeabilitas menurun dari 38,5 LMH/Bar ke 32 LMH/Bar dan rejeksi 82,35% sedangkan pada aliran crossflow permeabilitas cenderung konstan sebesar 58,5 LMH/Bar dan rejeksi 77,37%. Adanya penambahan NaCl pada larutan umpan, menyebabkan baik nilai permeabilitas dan rejeksi menurun. Permeabilitas menurun dari 57,03 LMH/bar menjadi 50,50 LMH/bar dan rejeksi menurun dari 76,9% menjadi 73,9%.
English Abstract
The textile industry produces wastewater with a dye content of about 40%. Generally, Remazol Red is used in the textile industry. The presence of Remazol Red in wastewater causes disruption of aquatic ecosystems and human health due to it being carcinogenic. Therefore, a wastewater treatment process is needed to remove the Remazol Red content in the wastewater. Nanofiltration membrane technology can be applied to remove Remazol Red because it has a pore size in the range of 200-500 Da, while Remazol Red has a Molecular Weight Cut Off (MWCO) of 984,2 Da. There are two types of flow configurations in the membrane process, dead-end and crossflow. This study aims to determine the effect of flow configuration on membrane performance. Nanofiltration membranes can be made with a thinfilm composite structure by forming a polyamide selective layer over the membrane support. Polyamide was made by an interfacial polymerization method with TMC/n-hexane solution and MPD/water solution. Textile wastewater contains a large amount of NaCl salt. Therefore, in this study removal of Remazol Red with a concentration of 200 ppm and variations in NaCl concentration of 0 ppm, 400 ppm, 800 ppm, 1200 ppm, 1600 ppm and 2000 ppm was carried out to determine the effect of NaCl concentration on permeability and rejection of polyamide thin film composite nanofiltration membranes.The membrane characterization based on the FTIR test showed the formation of polyamides in the presence of carboxylic acid (-OH), ketone (C=O), and amide (N=H) functional groups. Removal of remazol Red with dead-end configuration showed permeability slightly decreased from 38,5 LMH/Bar to 32 LMH/Bar and rejection 82,35% while in crossflow configuration the permeability tends to be constant at 58,5 LMH/Bar and rejection showed is 73,37%. The addition of NaCl in the feed solution affects both the permeability and rejection decrease. Permeability decreased from 57,03 LMH/bar to 50,50 LMH/bar and the rejection decreased from 76,9% to 73,9%.
