Desalination of seawater in Australia

Desalination of seawater in Australia Desalination of sea water with the new AUSTRALIAA Life-Line, or just a utopia? Desalination has been promoted as the savior for Australia? S current drought. E 'in a position to solve our long-term problems of water supply in Australia or is it an expensive pipe dream? It is the conversion of desalination of sea water into drinking water by a process of reverse osmosis. Saudi Arabia has long been with desalination plants for almost all their drinking water. They have invested billions of dollars in their system.Australia with its current water shortage is now available for research, but it is a case? Too little, too late? It is the horse bolted, before closing the door? Time in Weste Australia (WA) There is currently a proposal to create a $ 360 million desalination plant at Kwinana in Perth. A $ 4 million research project completed by the European Commission the green light for the construction of the plant in Kwinana, an industrial suburb of Perth.Victoria is a proposal and is currently a research project and feasibility study with NSW to follow the 'example. ? Sydney is of the opinion that there are only 2? up to 3 years of water left at the current rate. The NSW Govement is expected to top $ 2 billion desalination plant at Kuell (near Port Botany), early next year. This led to protests by local fears of serious environmental problems damage.In This article takes a brief look at the desalination plant that will soon be in Perth in Weste Australia, where they are able to convert sea water to freshwater. As you can convert sea water into fresh water? There are several ways to convert sea water to fresh.1.Boil to collect and condense the steam. This requires a lot energy.2.An technology has improved the pump water through membranes that trap the salt molecules and produces clean drinking water. This is called reverse osmosis. How do we know its going to work? The Rottnest Island off the west coast of the Australian coast was a small version of the last few years. Filtered water is pumped by a high pressure (to a value of 600 m below sea level) pump? Like its pumped, 6-membranes in the pipe, the largest block of molecules of salt. The equivalent of two standard bags of salt (as in salt to eat in restaurants to take away) from a glass of water. The salt brine is then pumped back out to sea.The desalination plant accounts for 70% of the whole island? The needs, and is powered by a source at 100 kW, 500 kiloliters of fresh water per day (18.3 Megalitres year). A 600kW wind generator on Rottnest Iceland provides energy for the rest of 'island and the desalination plant plant.Kwinana? The Kwinana plant is 25 megawatts, the 250-times the size of the plant and Rottnest Island is 50 years Gigalitres year. The plant will also contribute 100,000 tonnes of greenhouse gases. To combat the contribution of greenhouse gases, 20,000 cars from the road or an additional 8000 hectares of trees (or an equivalent of 9 km ²) will be planted by the WA govement is currently examining. In order to ensure a source of power for the desalination plant, the WA Govement will support the creation of more than 40 wind turbines, the size of Rottnest? S islands just to the power requirements of plant.Cost the cost for desalinated glassThe glass is 0.004c, which are also compared with the current price of 0.003c per glass with the existing water supply system. ? However, the cost to the environment is not at this price. ConclusionThe new Kwinana desalination plant is expected by October 2006. But who is he? The WA govement still hasn? T is a contractor to build it. The 50 year Gigalitre capacity falls behind Perth? Current demand for water from 1300 Gigalitres year. ? There will be a huge impact on the environment, at a time when we must take into account the reduction of greenhouse gas emissions are not increased in 'interest of all to planet.Considering that agriculture, industry, the evaporation and waste to 88% of our consumption of water [see Table 1], you should be? t we concentrate on the causes of water scarcity not only of an expensive spa?
