Development New Technology Can Generate Water With Competitive Price

Today, desalination is a common process that's used in seaside cities and towns worldwide. There are more than 15,000 desalination plants around the world providing freshwater from salt and brackish water alike (Planet Green 2011). This number continues to grow as researchers work to improve the process, both in terms of cost effectiveness and energy efficiency (DSE 2011). But countries such as Australia, Israel and even the United States are continually adding desalination plants of various sorts into their water-management portfolios. The facilities are common in North Africa and the Mideast, where freshwater is scarce (Chandler 2008).

1. There are two main sources of fresh drinking water, ground water and surface water. Ground water originates from precipitations that usually fall in the form of snow or rain. While, the surface water is also originates from precipitate that reaches the land surface and is then recharged into rivers, wetlands and lakes. Although these systems are usually reliable, in desperate time of need, a more reliable source of water is needed. The desalination plant is extremely valuable and flexible because it does not depend on rainfall. Instead, the desalination plant is the only source that relies on seawater. Using seawater in the desalination plant helps meet the community’s water needs and secures the water needs in the future. While other sources of water, such as rainwater or water from dames are not reliable enough to strictly rely

The Perth Desalination plant cost a total of $387 million. The annual running costs equals $20 million which equates to less than one dollar per week per household. The water produced from the plant has been estimated to cost $1.17/kl. The plant uses 180GWh/year and is sourced from Emu Downs Wind Farm, a local renewable energy generator near Geraldton and Cervantes. Although Desalination uses more energy than other water sources (i.e. gravity feeding water out of a dam). Different measures have been put in place to make the plant as economical and environmentally sustainable such as using energy from a sustainable source and by choosing the Reverse Osmosis technology. Reverse Osmosis is more economical and environmentally sustainable than other

The earth seems is drying up in certain areas of the world at the moment. We have already seen some of the hottest summers on record in the last decade. Summer 2016 was the hottest summer on record since the records were started back in 1880 (Doyle, 2016). The effects of this heat have manifested themselves as drought in areas of the western United States. One of those areas happens to be our home of Southern California. Water resources have slowly declined and conservation has been the key tool to battle the decline. In an effort to find new ways of conserving or creating fresh water supplies, technology has been called upon. The need for technology that can help us meet our fresh water demands becomes more important every day. One of the technologies that has gotten a lot of attention recently is desalination. In fact a large scale desalination plant was just opened in Carlsbad, Ca. The facility is capable of delivering 50 million gallons per day (MGD) (Bienkowski, 2015). Despite this impressive achievement the plant still only accounts for 8% of the total water demand in San Diego County (CDP, 2016). In this paper I will explain the process of desalination, identify a promising new technology, and provide a comparison of technologies.

When examining the process of desalination there are several advantages and disadvantages of the process that need to be examined, starting with the advantages. One of the major advantages of this process according to Gude (2016) is having the option to use renewable energy for the process instead of using fossil fuels. He states this is better for our environment and there will always be access to the wind, solar, or wave energy being produced compared to our fossil fuels which already are at a risk of running out. Haddad has also stated that renewable energy resources are better for our environment compared to fossil fuels, as they reduce our carbon footprint and the risk of climate change. Another advantage that can

There are many methods of desalination, however research shows that the most popular method is called multi-stage flash distillation (MSF), which accounted for 84% of desalination as of 2004 (Heimbuch, “How Desalination Works”).Multi-stage flash distillation uses energy from heat to evaporate salt water, and separate the water from the salt. This method of desalination can be very energy intensive, but fortunately multi-stage distillation can utilize solar power, making it a more environmentally friendly method of desalination. Other methods of desalination include forward osmosis distillation, reverse osmosis distillation, and low temperature thermal desalination (LTTD). The global need for more water in combination with emerging methods such as multi-stage flash distillation that utilize solar power, has the potential to evolve into a worldwide progression towards more environmentally friendly ways of

Freshwater is the most essential renewable resource for life, food production and industrial development. It is expected in the future soon the clean water resources will be deducted by one-third. The difficulty to purify water and the high cost to transport aggravates the problem of water deficits. Therefore, the exploitation of seawater and brackish-water desalination has drawn unprecedented attention. Desalination is a possibility choice to produce drinking water from Saline water, although most desalination processes are energy-consuming and expensive. The main desalination technologies currently used are reverse osmosis, electrodialysis, and distillation. A drawback of the conventional desalination technologies is the intensive consumption of energy. Whereas, energy consumption has increased with an enormous trend In the last decades. Fossil fuels are a common type of non-renewable which include a huge portion of energy consumption. Despite of being nonrenewable, fossil fuels also negatively affect the human life by the emission of carbon dioxide. This limitation turn energy crisis eyes into renewable energy sources such as solar energy or energy produced from wind and water. As a result, one of the lately suggested alternative energy sources is fuel cell (FC). FC has several advantages over other types of energy generators such as zero pollution and higher efficiency.

Water desalination is very important for us because it give us access to fresh and clean water. Also, water desalination is useful because we use it in many ways. For example, trees spraying , human consuming , municipalities, water glasses , hotels and resort. But also for industrial applications like power plants , oil and gas , chemical factories , requiring specific process water for their

Water is the nerve of life. It affects the food, energy, environment and health of billions of people living on the planet earth. Large populations living in vast arid areas around the world suffer from water scarcity. With exceedingly limited resources of water, about 200 million people distribute the Arab countries in North Africa, and the Middle East depends mainly on fossil groundwater that is a non-renewable resource. However, modern technology provides them a gift “Desalination” it is the technique of removing salt and other impurities from seawater in order to make it suitable for human use. This essay will discuss desalination as a necessary solution to water shortage in the future from various aspects such as sustainability, environment,

There are many ways to desalinate water to make them drinkable and they are proven and effective, and a few of them are reverse osmosis, multi- stage flash distillation and freezing. Reverse osmosis is when pressure is put on the water and forces the water through a membrane so that the water and salt separate, it has been proven effective in creating fresh sources of drinking water that can deliver the health benefits people need. When properly designed, desalination plants can then create drinkable water that is of high quality. This process can be used on different types of water, including brackish (low salinity) water and seawater [Science Direct].

Desalination of sea and brackish water is a common technique to alleviate the increasing shortage of fresh water in many areas of the world today. Nonetheless, desalination processes require large quantities of energy. In addition, the cost of the different desalination techniques is very closely linked to the costs of energy. Therefore, in a context of continuously rising energy costs and with the impending exhaustion of the conventional energy resources, the development of energy- efficient desalination technologies is a very attractive and promising prospect to solve these problems.

Desalination technology provides freshwater for regions with water scarcity problems and can prevent from over-using natural water resources. However, operating the plants may have some environmental, social, and economic issues.

Desalination is the most common process in the world, and because of the low percentage of fresh water and the consumption of groundwater reservoirs in many daily human uses such as, (Drinking, washing, bathing and also for agriculture and other uses...), and the entry of water in industries by a large proportion of between 70-90% so the water is an essential component in some industrial products, and also used as a refrigerant for the machines. Therefore, salt water desalination and reuse in industries and their appropriate uses have been

Desalination is the process in which excess salt water and other minerals are removed from water to make it consumable (Rosadoi, Moraisii, 2010). This source of water is very expensive to operate in rural areas of Kenya because the materials and running cost is on the high side. It has a lot of environmental impact, positively it is an additional source of water supply and it helps to keep the groundwater aquifers from going dry however the side effect of desalination is that it leads to the emission of greenhouse gases, large production of concentrated brine, discharge of salt by-product which is harmful to people residing around. Water born diseases will be reduced drastically and also creates job opportunities due to large industrial plants for processing. Source of steady electricity power to make this plant work will be a major concern and a large number of inhabitants make lack the technological knowledge to operate the desalination plants.
