ABSTRACT

Fresh water shortage is a growing problem facing the world, especially in the Middle East. With the rapid increase in fuel price, seawater reverse osmosis (SWRO) is increasingly becoming a popular option for water supply. To date several sea water reverse osmosis desalination plants have been built in the United Arab Emirates (UAE) to meet the growing demand for fresh water in the country. The Fujairah Water and Power Plant was acquired in 2006 by a joint venture company between the Abu Dhabi Water and Electricity Authority and Sembcorp, forming the Emirates Sembcorp Water and Power Company (ESWPC). The plant is operated under agreement by Sembcorp Gulf O&M Company (SGOMC). Serving as a brown field project, Sembcorp, through ESWPC Fujairah IWPP has made a commitment to supply 535 megawatts (MW) of power and 100 million imperial gallons per day (MIGD) of water, as well as an additional commitment of augmenting power supply to 760 MW from Feb 2009. Until 2005, the plant was the largest SWRO plant in the world. Today, after almost 5 years of operation, it still is the second largest SWRO plant worldwide and continues to provide inspiration for practical design and operational guidance for future plants.

Membranes deteriorate and are replaced due to the deposition of unwanted materials on the surface. In addition, a decrease in membrane performance may be due to other factors such as degradation by chemical (oxidation, hydrolysis, etc.) and/or mechanical (compaction, telescoping) processes. Extending membrane life and thereby minimizing replacement costs is a key success factor for reverse osmosis (RO) systems.

    Seawater Oceanography/SCI209 June 30, 2014 Professor Barbara Shoemaker Seawater The Earth is almost entirely surrounded by seawater. Through evaporation of seawater, water is returned to the Earth through precipitation. The precipitation allows for these salty waters to be filled with drinkable water. The combining forces of freshwater and salt water allow conversion techniques to turn undrinkable water into drinkable water. Such conversions help provide human life with water, one of the most…

    assignment is seawater obtained from the hydrosphere. The seawater can be separated through out several processes, both chemically and physically. The separation process is known as desalination. This name is getting more common everyday, as the Australian water demand grows with population we can no longer ignore the salinity problem. Desalination process could take use of the salt concentrated water, turning them into fresh water. Industrial Separation Procedure: 1. The seawater is inputted through…

    Membrane Processing MEMBRANEFILTRATION A membrane or, more properly, a semipermeable membrane, is a thin layer of material capable of separating substances when a driving force is applied across the membrane. Membrane filtration enables to separate particles with a diameter smaller than the pore diameter in the membrane from the liquid feed, by applying a driving force (pressure) over the membrane. The membrane technology consists principally of Microfiltration (MF), Ultrafiltration…

    Civic duty never meant much to me until I involved myself in the Ro Khanna for Congress Campaign. It began with a 6 hour shift to run a booth and ended with a celebration two weeks ago for Ro’s success in winning the congressional election. I have made phone calls and knocked on people’s doors to talk about why they should vote for Ro. As my volunteer activity increased, I became my high school’s team leader for the election. My responsibilities included gathering more volunteers, contacting old…

    osmosis is the most popular technology for seawater desalination. During the last two decades hundreds of reverse osmosis seawater desalination plants have been built worldwide (Jamal et. al., 2004(c2)). Recently the reverse osmosis has achieved growing acceptance as an economical and viable alternative to multistage flash distillation (MSFD) process for desalting seawater [.1.2, 5 in c2]. It is a pressure-driven process whereby a semi-permeable membrane rejects dissolved constituents present in the…
