Desalination of Seawater May be Our Answer - 668 Words

Situation/context With the increasing demand for water placing pressure on existing supplies, seawater presents an enormous source to satisfy demand. However, seawater cannot be directly consumed and therefore, desalination of seawater is necessary to make it safe for consumption [1]. The current methods involving desalination utilize mostly non-renewable energy sources such as coal and gas to provide the necessary energy for the process to take place. Identification of problems The current method used to desalinate water is multi-stage desalination (thermal desalination), which requires a significant amount of energy. As research has shown, for every cubic meter of desalinated water, 1.3 kWh of electricity and 48.5 kWh of heat are consumed [1] which shows that more than 90% percent of the energy supplied is wasted as heat. Furthermore, the current methods utilize non-renewable sources of energy, which eventually produce greenhouse gases such as carbon dioxide. These non-renewable sources of energy, mainly fossil fuels are short in supply and eventually will run out. Therefore, it is important to look for an environment-friendly long-term solution. Research Question How can solar ponds be utilized to carry out desalination of seawater? What large scale, feasible model can be developed to achieve desalination through solar ponds? Research Methodology We intend to mainly utilize secondary resources through the Summon search application provided by the AUS Library.Show MoreRelatedScience Investigatory Project1698 Words   |  7 Pagesworld’s supply of energy will finally be met if this proposal will push through. Since saltwater is renewable, there are already some technologies that can harness it and convert it to electricity for the world to use. With this in mind, we hope to answer and find a solution to world’s energy crisis through this project. B. STATEMENT OF THE OBJECTIVE: As all other countries in the world do, the Philippines are also faced with the problem of the rapid depletion of natural resources.

After more than five years of drought in California, we are just now beginning to see an above-average precipitation,and this is leaving many to ask, is the drought over? This last drought was one of the worsts droughts California has experienced in history and it left many panicked and trying to come up with solutions. â€Å"Governor Jerry Brown even made one of the first cutbackRead MoreDesalination And Its Impact On The Environment2112 Words   |  9 PagesDesalination and its Impact Authors: 1*Miles Smith Affiliations:1Dartmouth College *Correspondence to: Miles.F.W.Smith.19@dartmouth.edu Abstract: In the last few decades, large scale desalination plants have been constructed in countries where water scarcity is an issue in hopes of providing these countries with additional water resources. As the number of water crises increases globally, the number of desalination plants is expected to increase as well. Although the technology has rapidly advancedRead MoreA Research Study On The Drought1046 Words   |  5 Pageswhich water will be valued more than gold will become our final destination. Thus, many world powers are seeking for an alternative water source. An example of it can be desalination. Yet, the negative effects outweigh the benefits of such method. Not only the marine animals get seriously endangered since none of them are able to survive through the desalination process, but also the need to dispose of hyper-saline brine, a byproduct of desalination. Moreover, the building of such facility is very expensiveRead MoreCalifornia’s Splashy Splash Scarcity1341 Words   |  6 Pagesmanagement of our water resources which worsen the drought. The mere idea of running out of water is not to be taken lightly, only a small amount on our planet is safe for human consumption; keeping that in mind Californians must face the necessity to rationalize water in order to cope with the concurrent crisis. The practice of rationing will help maintain water levels. The expected result of this calamity is water shortages and a major impact in the agricultural level across ou r entire state.

The only issue is the salt content found in seawater; this has not hindered more than 120 countries with 21,000 desalination plants running currently. The San Diego region has been a center for the development of international desalination technology through the investments and progress from Poseidon Water and we now have the Carlsbad Desalination Plant; which now occupies 6 acres of the 388 acre oceanfrontRead MoreCalifornia Must Invest For Cost Effective Long Term Drought Solutions1058 Words   |  5 PagesCalifornia Must Invest in Cost Effective Long-Term Drought Solutions Aldrin Biltz, Conflict and Conflict Resolution, May 17th 2015 I. Background and Context: It has been confirmed that the year 2013 has been recorded as the driest year since California became a state, 165 years ago. This means California has been and is now experiencing its worst drought ever in history. Precipitation and snowpack levels remain well below average, and there does not seem to be an end in sight.
