“…However, when using ED technology for desalination, treatment cost is directly related to the TDS concentration in feed. This technology is best used in treating brackish water with TDS up to 4,000 mg L 21 and not economical for higher TDS concentration (Younos & Tulou 2005).…”

“…Thermal technologies are used primarily for seawater desalination and rarely discussed for brackish water desalination. 307 Membrane-based desalination technologies are more advantageous for brackish water desalination over thermal technologies, due to the lower energy consumption at low salt concentration. 308 A brief description of energy intensity of brackish water RO is found below; please refer to Appendix B (Section B.2.2.)…”

PrefaceReducing energy consumption through investment in advanced technologies and practices can enhance American manufacturing competitiveness. Energy bandwidth studies of U.S. manufacturing sectors serve as general data references to help stakeholders understand the range (or bandwidth) of potential energy savings opportunities. The U.S. Department of Energy's (DOE) Advanced Manufacturing Office (AMO) has commissioned a series of bandwidth studies to analyze energy-intensive processes and provide technology-based estimates of potential energy savings opportunities. Most recently, AMO has commissioned a bandwidth study to analyze the energy consumption characteristics of desalination systems for municipal water. The research will determine the energy consumption and carbon emissions implications of increasing the share of potable water in the United States provided by seawater desalination. The consistent methodology used in the previous bandwidth studies has provided a framework to evaluate and compare energy savings potentials within and across manufacturing sectors at the macroscale and will now be applied to the technology study area of desalination systems. The Energy-Water Bandwidth Study of Desalination Systems will expand the scope of previous bandwidth studies by also evaluating the carbon dioxide (CO2) intensity and reduction opportunities and will inform a techno-economic analysis of desalination systems.The complete information for this study will be provided in two volumes: Volume 1: Survey of Available Information in Support of the Energy-Water Bandwidth Study of Desalination Systems (this report) reviews the parameters that impact energy, emissions, and cost considerations, and provides background research and a framework for Volume 2: Energy-Water Bandwidth Study of Desalination Systems. Table P-1 shows the specific contents of the two volumes. With growing interest of desalination to meet domestic and global potable water demands, available results should be distributed as soon as they are developed; hence, Volume 1 is published in advance of Volume 2, and serves as an interim report for the Energy-Water Bandwidth Study of Desalination Systems.

“…Salah satu teknik filtrasi yang bisa digunakan adalah teknik filtrasi menggunakan membran. Membran adalah lapisan tipis semipermeabel yang banyak digunakan pada proses pemisahan dan pemekatan (Younos and Tulou, 2005). Membran memisahkan material berdasarkan ukuran dan bentuk molekul, menahan komponen yang mempunyai ukuran lebih besar, dan melewatkan komponen yang lebih kecil.…”

ABSTRAKPencemaran perairan merupakan masalah yang selalu dihadapi oleh industri batik, terutama akibat pemakaian pewarna tekstil. Teknologi membran merupakan salah satu metode yang dapat digunakan untuk pengolahan limbah cair. Membran merupakan lapisan tipis yang berfungsi sebagai filtrasi. Salah satu bahan baku pembuat membran adalah selulosa bakteri. Selulosa bakteri adalah selulosa hasil fermentasi bakteri Acetobacter xylinum yang mengubah glukosa menjadi selulosa.. Penelitian ini memanfaatkan rumput laut jenis alga cokelat (Sargassum sp.) yang dianggap sebagai sampah di pantai sebagai sumber glukosa. Fermentasi alga cokelat dilakukan dengan 3 variasi waktu fermentasi yaitu 7, 10, dan 13 hari. Selulosa bakteri optimum yang dihasilkan adalah selulosa bakteri dengan waktu fermentasi 10 hari, berwarna putih dengan ketebalan 1 cm. Membran Sargassum sp. dihasilkan dengan cara pengepresan selulosa bakteri. Hasilnya membrane Sargassum sp. memiliki ketebalan sebesar 1,8 mm, fluks sebesar 3,386 L. m -2 .jam -1 dan rejeksi sebesar 39,34%. Membran Sargassum sp. digunakan untuk menurunkan konsentrasi zat warna batik dengan cara filtrasi. Zat warna tersebut adalah rodamin B, metilen biru, dan metal jingga. Penurunan konsentrasi yang diperoleh untuk masing-masing zat warna rodamin B, metilen biru dan metil jingga berturut-turut adalah 80,04; 77,83 dan 75,84%. Penelitian ini menunjukkan bahwa membran Sargasuum sp. dapat digunakan dalam pengolahan limbah cair industri batik. Kata kunci : Acetobacter xylinu, membran, Sargassum sp., selulosa bakteri, zat warna ABSTRACT Water pollution is a persistent problem faced by the batik industry, mainly due to the use of dyes. Membrane technology is one method that can be used for wastewater treatment. The membrane is a thin layer that serves as a filtration. One of the membrane raw materials is a bacterial cellulose. Bacterial cellulose is a cellulose which is produced from Acetobacter xylinum fermentation that converts glucose into cellulose . This study utilized brown algae (Sargassum sp.) which is regarded as trash on the beach, as a source of glucose. Brown algae fermentation carried out for 7, 10, and 13 days. The optimum resulting bacterial cellulose is the bacterial cellulose with 10 days fermentation, the color is white, and the thickness is 1 cm. Sargasuum sp. membrane are produced by pressing the bacterial cellulose. The Sargassum sp. membrane thickness is 1.8 mm, the flux is 3.386 L m -2 .h -1 and the rejection is 39.34%. Sargassum sp. membrane is used to reduce dye concentration of batik by filtration. The dyes are rhodamine B, methylene blue, and methyl orange. Decreasing concentration for rhodamine B, methylene blue, and methyl orange respectively are 80.04; 77.83 and 75.84%. This study shows that the Sargasuum sp. membrane can be used in wastewater treatment of batik industry.
