Desalination: The Solar System

According to David Sedlak, we have made large progress in seawater desalination for the past 2 decades. The largest seawater desalination plant in the Western Hemisphere that is built north of San Diego uses half of the energy use than Santa Barbara 25 years ago. One reason why Sea Water is a good way to save more groundwater because we do not have a lot of water, but lots of oil. Also seawater desalination is not always good, there is a negative side. It is energy intensive; that means that it will cause a lot more climate change, but that is the only negative thing David Sadlak had mentioned about seawater desalination; but so far the new seawater desalination plant uses half the energy it used to. This would help California because it would lower the amount of water that is pumped from the ground, therefore, seawater desalination is a possible solution for conserving more

Since the discovery that desalination could provide humans in California with clean potable water from the ocean could be very effective, it

Should California start to desalinate Ocean water? California should not start to desalinate ocean water

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).

A desalination plant is a possible alternative to California’s need of consumable water. There is a course cons against desalination mainly affecting the marine environment for leaving highly concentrated saline water behind through the process but we should not fear it as it is a long term solution we cannot toss aside. Kerry Cavanaugh from Los Angeles Times mentions, “2,000 an acre foot, compared to about $1,000 an acre foot for imported water” (par. 3). This means that production of water through this process is cost efficient and seems rather illogical to spend more money into producing water; instead of importing it from another major source. The process cost is not a major step forward, but the idea of reaching out to import water is rather absurd. California is an arid state; we are the ones responsible for turning it into a paradise. In order to maintain it that way a method to lower the cost of desalination can be propose as solution. The thought

The advantages of desalination represents an opportunity to use oceanic water resources. If the appropriate conditions are present, a desalination plant could potentially be used to replace an existing or future dam. As existing sources of useable water run dry, desalination is a very effective, alternative source of water. On top of that the distillation process produces one of the highest quality water, with a range of 1 to 50 ppm tds, tds is also known as total dissolved solids. With the recommended California standard being 500 ppm, this quality of water is far beyond any other water quality seen before.

Desalination is the process of removing dissolved salts from water which makes it more useful and it makes it so if you drink the water you will not dehydrate faster and die.The water after the desalination process is utilised for drinking water , crops like corn and wheat , showers , washers , municipal / potable use and for agricultural irrigation but is also used extensively in many other applications where high quality water is required .

Another argument opposing desalination is the environmental concerns. Many believe that since ocean water is being extracted, marine life will be disturbed. Therefore, affecting the entire ecosystem: “With the majority of desalination plants extracting water directly through open water intakes in the ocean, there is a direct impact on marine life. Fish and other marine organisms are killed on the intake screens (impingement); organisms small enough to pass through, such as plankton, fish eggs, and larvae, are killed during processing of the salt water (entrainment). The impacts on the marine environment, even for a single desalination plant, may be subject to daily, seasonal, annual, and even decadal variation, and are likely to be species- and site-specific” (Cooley).

Desalination is the process of removing dissolved salts and minerals from seawater or brackish water. (WaterReuse, Association, “What is Desalination?”) A desalination plant essentially

water and increase the amount of it. However, it thought about desalination plant. What does desalination mean? Many people do not know the meaning of desalination and it is important to know the meaning to confident them when they use the water after desalination. It is the process of removing salt and any gas from seawater to be valid for drinking, watering, manufacturing and so on. The desalination plant has major challenges, which is the high cost because they need to use a high-level technological to remove the gas and the salinity of the water. In addition, the water after the process needs to test to be sure about the validity of using it. The UAE has desalinated seawater because they cannot use the water directly, it consists salt and

How can seawater from the oceans be turned into fresh water that is suitable for people to drink? Through a process called solar desalination! In this science project, you will make a solar desalination apparatus using readily available materials, and a power source that is free. How much water can the device produce, and is it still salty at all? Typical seawater contains dissolved salts at concentrations between 32 and 37.5 parts per thousand. That means that if you started with one kilogram of seawater (which is approximately one liter of seawater) and then you allowed all of the water to evaporate, you would be left with between 32 and 37.5 grams of salts (also called "total dissolved solids"). With all of that salt, seawater is not suitable

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

Approximately 72% of the earth is covered in water, however, of that amount, 97% is undrinkable because of the saline content. Theoretically, the ability to make that portion drinkable would mean creating a renewable source of fresh water-- a concept that, if executed properly would mean the end of water insecurity worldwide. The first record of desalination technology being used came from the writings of Aristotle, a Greek philosopher who lived during the fourth century BC. Ancient Romans used evaporation to remove the salt from water to make it potable. Since then, desalination has become much more sophisticated, but the latest technology being used is still decades old ("A Short History Of Desalination - Abengoa"). Although

Many benefits arise with the implementation of desalination plants by producing new forms of drinkable water in places where more common sources of clean water

Australia, as the driest inhabited continent, had installed 331 desalination plants supplying high quality water to the increasing population. Another country, China, also implete the use of desalination plants to tackle the drought and large population problems. This section will compare several technologies used in these two countries. As shown in Table 1, RO is the most used technology in both countries, accounting for 61.03% in Australia and 81.3% in China.
