"Is Water desalination a viable option to meet global water demands"

Download file to see previous pages Water scarcity has forced the scientific community to look for alternative water resources and one of the most popular options is using the water of the oceans that is vastly available. Desalinating the ocean water and making it fit for human consumptions is one of the most important solutions to the water issues that man faces today.
the most remarkably true phenomena is that out of the 2.5% of the fresh water that is available moat of it is trapped in the polar ice caps while only less than 1% of this freshwater is found in lakes, rivers, reservoirs and sub-surface aquifers and is thus available for direct human use. The United Nations estimated that 1.4 billion cubic kilometers of water is present on the Earth and only 200,000 cubic kilometers of this represents fresh water. At the continental level America shares world’s total freshwater resources (45%).Surface water present is highly polluted while indiscriminate withdrawal of groundwater for agriculture and contamination of the water have depleted these resources and hence there is need for some technology to help with the water scarcity issues.
Owing to the decreasing groundwater resources and water scarcity problems and the subsequent effect this might have on world food production there have been dramatic changes in the world’s resource management approaches (Gleick, p127). Desalination activities are being done in the Arabian Gulf areas today but increasing number of countries are considering the pros and cons of adopting desalination technologies to meet the demands of the population. Desalination of water means using ocean or brackish water and removing salts and other minerals from the salty water to produce clean, drinking or potable water that is fit for human consumption and usage.
Primarily Desalination is done by two different methods-thermal and membrane process. Desalination facilities use one of the five basic technologies to “extract potable ...Download file to see next pagesRead More

Global water crisis
...will need to integrate with. Yet, this has the potential to continue to generate water at an undiminished rate over time. This demand for a far greater supply of electrical energy that would be required to power these plants also has a negative environmental cost due to the fact that electrical production is inherently tied to CO2 generation and or the use of nuclear fuel to power the reactors that ultimately produce the power that would be used for the desalinization process. When one traces the environmental costs of the desalinization process to its root end, other factors are discovered which must be weighed to differing degrees Naturally, although the economic costs...

Global Water Shortage (Sudan)
...? Water Problem Global Water Shortage Water has proved to be a scarce commodity in most parts of the world, especially the clean drinking water. As per today, close to 1 billion people in the developing world do not have access to water. Yet, some of us take water for granted, by just wasting it (Biswas, 2008). Water being the fundamental of life, it is ironical to see some people taking a whole day searching for it. Instead, it was supposed to be adequate for everyone, equally. In places like the Sub-Saharan Africa, people take too much of time looking for this precious water, thus...

...”. The statistics presented above are indicative of the fact that there is a shortage of water at the global level and that the world is moving towards a crisis that could affect not only the present generation but also the generations to come. It has been quoted in the article “Global Water Shortage Looms in New Century” (n.d.) “Within a few years, a water crisis of catastrophic proportions will explode upon us unless aroused citizens ... demand of their leadership actions reflecting vision, understanding and courage." To overcome this problem I think it would be necessary to reflect on its causes and consequences so that proper...

Water Desalination using Vacuum Membrane Distillation
...1. Membrane Distillation (MD) Vapor pressure difference is the driving force behind membrane distillation. The surfaces of the hydrophobic porous membrane are maintained at different temperatures, causing the vapor pressure difference. Conventional membrane distillation processes sometimes lead to extreme membrane fouling; MD reduces this problem [6-11]. Membrane distillation has been used to concentrate fruit juices and for wastewater treatment, and many industries are interested in studying and applying it since it yields highly purified permeate and separates contaminants from liquid solutions. Of course, it can also be used for water desalination [5]. Vapor migrates from the membrane surface to the...

Water, Water Everywhere: Hydropower
...successfully be changed. (National Hydro power Association, 2015) Here, water is pumped to the dam above the power plant from a reservoir below during the low season such as in the middle of the night and the then allowed to flow downwards during the day thereby generating the much needed power. (The UAGS Water Science School, 2014). All above are the disadvantages associated with hydroelectric power generation. However, as explained, there are solutions to all the problems hence, these problems should not hinder the use of hydroelectric power from being adopted in our country. In America, there lie so many viable locations where hydroelectric power can be harnessed. According to the...

...successfully desalinated ocean water in a bid to curb its clean water shortage. This process was conducted by the Sorek plant that produces approximately 165 million gallons of fresh water. In this respect, desalination of ocean water is arguably one of the best approaches that can be used to address the global water crisis, owing to its successful implementation by Israel. It is also worth noting that desalinated ocean water may transform arid lands into viable lands economically and hence boost agricultural productivity. The use of...
