However, seawater intrusion has spread into the wetland aquifer and reduce the quality of water. Silica-pectin membrane is a promising technology for desalination. The membranes were tested for desalination by pervaporation at room temperature (~25 °C). During pervaporation process, the water contacts to membrane and the separation is started to occurs as vapour phase by maintaining vacuum pressure (~1 bar). The permeate was collected in the cold trap after condensed using nitrogen liquid. The purpose of this research was to investigate the performance of interlayer-free silica pectin membrane for wetland saline water. Experimental results shows the fluxes of membrane are 0.35 and 0.19 kg.m -2 h -1 ( pectin 0%wt); 0.23 and 0.16 kg.m -2 h -1 (pectin 0.1%wt); 0.58 and 3.63 kg.m -2 h -1 (pectin 0.5%wt); 3.40 and 0.12 kg.m -2 h -1 (pectin 2.5%wt) calcined at 300 and 400 °C, respectively. Natural organic matter (NOM) and salt concentration in wetland saline water can reduce the fluxes up to (~98%). Nevertheless, overall salt rejection of membranes achieved >99%. It was found that low calcination gives better performance at high pectin concentration. While pectin concentration was limited at high calcination.}, issn = {2597-9914}, pages = {99--104} doi = {10.14710/jksa.22.3.99-104}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/22632} }
