“…In general, there are three types of membrane process that are usually applied, it is called reverse osmosis (RO), membrane distillation (MD), pervaporation and ultrafiltration [28]. Among various water treatment technologies, ultrafiltration (UF) is an alternative technology to improve water quality [26]. UF is a promising and the most widely applied technology for producing water consumption from surface water with a lower cost [29].…”

South Kalimantan has natural surface water such as wetland water which easily found to prevent water scarcity. Two types of wetland water provided in tropical area i.e. (1) peat water which located in land area; and (2) wetland saline water that area is near to coastal zone. Both are unsuitable for consumption and required to be treated. Ultrafiltration (UF) is one of methods that can be applied for treating natural wetland water using silica membrane. However, it needs improved by carbon due to lacking its low hydrostability properties. This works investigated performance of banana pectin templated silica ultrafiltration membrane in varied operation pressure and feed water treatment. Preparation of ultrafiltration membrane was used banana peels pectin as carbon source that templated into silica sol through sol gel process. Silica pectin xerogel was characterized by Fourier Transformed Infra-red (FTIR) and morphology of silica pectin membrane was characterized by Scanning Electron Microscopy (SEM). The sol is carried out by a coating process to the alumina membrane support on 4 layers. The calcination process is using the Conventional Thermal Processing (CTP) method. Furthermore, the ultrafiltration process run on the dead-end ultrafiltration silica pectin membrane has three functional groups, namely siloxane (Si-O-Si) at a wavelength of 1061 cm-1. silanol (Si-OH) at a wavelength of 966 cm-1 and silica carbon (Si-C) at a wavelength of 795 cm-1. The performance of silica pectin membranes at pressures of 0.5 bar, 1 bar and 1.5 bar in peat water resulted in fluxes of 5.07 kg.m-2.h-1, 11.31 kg.m-2.h-1 and 18.90 kg.m-2.h-1 with rejection of organic matter of 85.56%, 85.49% and 84.68%. Meanwhile in wetland saline water it was 7.04 kg.m-2.h-1, 11.73 kg.m-2.h-1 and 20.52 kg.m-2.h-1 with rejection of organic matter of 82.50%, 79.46% and 78.11%. Salt rejection for wetland saline water for 0.5 bar until 1.5 bar is 84.39%, 82.54% and 81.04%. Ultrafiltration It can be concluded that the increase in pressure affects the performance of the silica pectin membrane where the flux value increases with each increase in pressure, but the rejection value of organic matter and salt rejection show a decreasing.

In South Kalimantan, peat water is the main water sources for local people. But peat water has high iron content. It cannot be consumed directly and need further treatment. Adsorption is the most common technology to treat peat water. The goal of this research is to study sago waste adsorbent for iron removal in peat water. Citric acid was employed as activating agent in the sago waste activated carbon adsorbent fabrication. Carbonization process was done at 300 ℃ with 70, 80, 90, 100, 110 and 120 minutes of time variation. After treatment using the adsorbent, iron content was tested via Atomic Absorption Spectrophotometry (AAS). While, Fourier Transform Infra-Red (FTIR) were carried out to investigate the functional groups of sago pith waste activated carbon (SPWAC) and sago pith waste unactivated carbon (SPWUC). The experiment results show iron could be removed until 82% with iron concentration of 0.05 mg/l at 80 minutes. SPWAC and SPWUC have functional groups such as alkenes (C-H and C=C), carbonyl (C=O and C-O) and hydroxyl (O-H). Fe concentrations are still meet water quality standard according to No. 492/Menkes/PER/IV/2010 which is 0.3 mg/L. Therefore, adsorption uses sago pith waste activated carbon is an effective and inexpensive water treatment.

“…Pervaporation is a desalination technology to produce a clean water with relatively low energy consumption compared to reverse osmosis membranes but still produces relatively a high flux (Kaminski et al, 2018;Rahma et al, 2019). Pervaporation has offered several advantages such as high selectivity, low operating costs, can be operated at low pressure and high temperature, and offers a higher molecular sieving compared to zeolite and organic membranes (Mahmud et al, 2020;Syauqiyah et al, 2019). The pervaporation process generally uses an-organic membrane made from silica (Rahma et al, 2019).…”

The sol gel process is one of the processes used in the manufacture of thin films on membranes because it can control the pore size in the resulting silica matrix. In addition, another way to build membrane size can be done by adding catalysts and precursors to be used. In this study, using a combination of tetraethyl ortho silicate (TEOS) and triethoxy vinyl silane (TEVS) precursors and citric acid as a catalyst to produce a silica matrix with mesoporous size so that it is suitable for application in the desalination process. The organo silica membrane was calcined at 350 ° C for 1 hour using the RTP calcination technique under vacuum, thus preventing the decomposition of carbon in the silica matrix. The membrane was dipcoated 4 times to obtain 4 layers. The FTIR (Fourier-transform Infrared Spectroscopy) test was carried out to see the functional groups on xerogel, namely silanol, siloxane and carbon. In addition, the performance of this membrane is carried out by desalination through pervaporation using 0.3% NaCl feed water with variations in feed air temperature, namely 25 ℃, 40 ℃ and 60 ℃. The resulting flux of air value increased with increasing feed water temperature, namely 6.1; 11.2; and 12.1 kg.m-2h-1 while the resulting salt rejection was 99.72; 99.64 and 99.23%. So that the organo silica membrane is suitable when applied to the desalination process through pervaporation.
