Use Of Geothermal And Solar Powered Desalination

When the water or lava comes up from the inner core from either a volcano or from a geyser, the temperature of the liquid it produces would be able to produce the same result we get from using fossil fuel to supply our energy. Geothermal energy could possibly be used to directly heat buildings or used to power turbines and thus generate electricity.

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

He or she cites a couple examples of geotheramal water usage in Oregon and New Mexico. Both of which used it as a heating source in various different applications. In Oregon, it was used to keep roads and sidewalks from freezing over during the winter season. Also in New Mexico, the same principle was used to to keep the soil beneath the corps from freezing which resulted in a longer growing season. These are great advantages that support his defence on geothermal energy usage.

Desalination has been used for hundreds of decades, Greek sailors heated water to evaporate fresh water away from the salt and other minerals, and the Romans used some clay filters to trap salt. Today's urbane methods still mostly use the concepts of distillation or filtration. The procedure of desalinating sea water to produce drinkable fluid has a long and gorgeous history. Nevertheless, the first significant modern desalination process to perform was multi-stage flash distillation type (MSF) it is a process that originally started during the mid-20th century in the USA (1955). Moreover, even though multi-effect distillation had been revealed and had the potential to be more effective than multi-stage flash desalination (MSF), it took a

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

Although water desalination was introduced and has helped many countries in aleviating their scarce water supply, the process itself is steadily decreasing in use due to the extreme cost it takes to run each and every desalination plant in these countries. The technology, machinery, and fossil fuels being used are far to expensive to continue using desalination as a method of providing water to countries in need. For this reason it is necessary that solar energy and forward osmosis be introduced into the desalination plants for the simple reason of being able to save countries fossil fuels and money. With these two new sources of energy being implemented into the plants, the water that is filtrated through the desalination process will be more efficiently spread throughout countries that are located all throughout the solar

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

When nature limits our accessibility to water by droughts, we face no other choice but to turn toward the oceans for water. In that case we have to desalinate ocean water in order to purify it. The two most commonly known methods for desalination used around the world are Reverse Osmosis and Vapor Compression Desalination. We may take these two advancements in technology for granted in our daily lives and overuse the constantly flowing water. We need to take into consideration the amount of energy and effort required to purify water using these two processes. As the population grows in the drought areas the need for producing desalinated water is also going to increase, as

Big scale desalination is a procedure through which sea water is pumped to a treatment office where the salt is extricated through a procedure of reverse osmosis to make the water fit for household use. San Diego County is at present developing the biggest desalination plant in the western side of the equator, at an expense of $1 billion. That plant, situated in Carlsbad, will give enough safe water to around 300,000 individuals, and will serve as a noteworthy test of the practicality and cost of utility-scale desalination innovation when it starts operation in November.

Desalination has been used for thousands of years - Greek sailors boiled water to evaporate fresh water away from the salt and Romans used clay filters to trap salt. Today's sophisticated methods still generally use the concepts of distillation or filtration. The process of desalinating sea water to make it drinkable has a long and rich history. However, the first large-scale modern desalination process to appear was multi-stage flash distillation (MSF) during the mid-20th century in the USA (1955). Furthermore, although multi-effect distillation (MED) had been discovered and had the potential to be more efficient than MSF, it took a while longer to make the MED process efficient on an industrial scale and this did not occur until 1959 when

The U.S. Department of Energy Geothermal Technologies Program’s report, A History of Geothermal Energy Research and Development in the United States published in 2010 is a four volume series that covers the thirty year period between 1976 and 2006 of growth and development of geothermal energy in America. This report is as the primary source detailing what started the exploration, how it will be accessed, the engineering

All major desalination plants in Australia incorporate energy recovery devices to minimize overall energy requirements. Also, a worldwide research and development effort is currently devoted to reducing the energy consumption of desalination processes. A report by CSIRO and WSAA has identified that the energy demand profile for water supplies was influenced by the uptake of desalination in Australian cities. “In South East Queensland, desalinated and recycled water made up around 10% of the water supplied in 2009/10. The treatment energy for these rainfall independent water sources made up more than 40% of the total energy for water supply treatment and pumping.”(Cook, Hall & Gregory
