Desalination Research Papers

However, due to the long lasting drought in California we should heavily consider this method of producing clean water. In other parts of the world such as China, India, Australia, Spain and more they have been able to produce nearly fourteen billion gallons of drinking water through this process. The largest desalination plant in the world is located in Saudi Arabia and produces two hundred and seventy three million gallons of drinking water per day. If the United States is able to perfect this, it could fix the situation. Amanda Little does an excellent job of sharing a wide array of perspectives of desalination in her article “Can Desalination Counter The Drought”. For instance she describes the discusses the standpoint of the executive director of the California Coast keeper Alliance, Sara Aminzadeh, as she argues, “It’s just not a good option from a cost and energy standpoint.” She goes on to say, “Desalination may seem like a panacea, but it’s the worst deal out there.” Although this method may not be cost or energy efficient, this may be the only plausible method of producing clean water. As seen in Saudi Arabia this is an efficient form of creating clean water and due to the lack of resources, this may be California’s last

Desalination is basically the procedure of separating excess sodium chloride, minerals and impurities from sea and ocean water to make it usable for irrigation and human consumption. It has been touted to rid the world of its current water problems for nearly 5 decades now, during this period huge strides have been made in the desalination technology. These advances have made it possible to venture into desalination as the long term option to the water problem in many parts of the world. It is seen as long term since the ocean is not going anywhere anytime soon as compared to lakes and rivers that have been going dry seasonally. The state of California is not new to the water shortage problem; as stated above tit has been a witness to previous droughts. It is therefore time to consider a long term solution to this problem.

With the water crisis being seen around the world, even right here in the United States, we need to explore other options to supply fresh water to the residents. One State, in particular, that raises concern is the state of California. An alternative method to supply water to residents could be the process of desalination. Desalination is when fresh water is made by using either seawater or brackish and eliminating the minerals and salts as a way to make the water safe for human and agriculture uses ( Kesieme et al., 2013). In recent years, we have seen an increase the in the number of desalination plants around the United States (fig 1). However, is the process of desalination the answer for the water crisis going on in California? As a

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

Desalination is one of the more popular options being considered to attempt to terminate the drought. Desalination is a process through which salt water is pumped from the ocean in to a treatment facility, and then the salt is extracted to make it possible to be used domestically. This is a long drawn out process, which involves seven different steps. The steps of desalination include the

Though conservation is all and good, but the option of desalination has a flashier appeal. Tap the Pacific Ocean. Pump water from the ocean, remove the salt and drink. State officials are evaluating 15 proposed desal plants, and the largest such facility in the Western Hemisphere will open in Carlsbad this year.

Desalination allows the removal of all impurities from water, through the use of chemical engineering, at a reasonable cost that is affordable to low-income areas (Lopez-Gunn and Llamas). Desalination being used in Flint could help prevent the abundance of lead in the water and allow the Flint River to still be used for the source of water. Instead of spending $12 million to reconnect to Lake Huron, this type of water system could save the city money and end this crisis (Robenznieks). Another way desalination can help is in Africa. Earlier it is mentioned that students created their own filtering system to help communities in Africa. This connected the students with the people in the villages along with the country through this change that was being made because of the water. However, with this new desalination system, instead of allowing a filtering system, it allows for a public water supply in African communities. Currently, global desalination is taking place in North America (16%), Europe (13%), Asia (11%), Africa (5%), as well as several other countries (Lopez-Gunn and Llamas). Lopez-Gunn and Llamas go on to explain how even though the number of this type of system isn’t very high in some areas, the breakthroughs in recent technology allows it to be more affordable and become an option being considered. No matter where in the world the water issue is, it can be fixed by

While desalination, is indeed an effective long-term solution, it isn 't necessarily the most cost competitive method, because it can cost four to eight times more expensive than alternative solutions.

Desalination has been a hot topic as a possible solution. What desalination does is takes sea water and convert it into fresh water. The major hurdle with this is the cost and people that protest against it. Companies will need to first get over the initial cost of building a desalination facility. Despite this companies such as Poseidon Water has a contract with San Diego to construct a desalinations plant in Carlsbad (Neill). Protesters have complained about the effects of desalination on the environment. Desalination requires large and powerful pumps to extract the water. These pumps potentially could destroy habitats and marine life that live near it. This is not the case for Carlsbad plant as it has already gone through extensive governmental

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

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

Desalination is the process of using seawater or brackish groundwater and converting to fresh water by removing the dissolved salts to allow the water to be suitable for human and agricultural purposes (Kesieme et al., 2013). The purpose of this process is a response to help meet the growing demand in water usage and protects the regional water supplies against the negative effects of climate change. However, consideration will need to be taken on the cost to maintain this expensive technology as well as the amount of energy required to operate the machine which will cause an increase in greenhouse gas emissions and an increase in water prices. The process of desalinating seawater provides a continuous amount of high quality water without significantly affecting the natural freshwater ecosystems. However, there are still concerns regarding the potential negative effects it has environmentally and economically.

Desalination, a process of extracting freshwater from seawater is energy intensive and comes with a number of environmental concerns. Adopting the process as a means of solving water scarcity challenge becomes necessary if other unconventional means cannot sufficiently meet the high-water demand. This is largely the case in the MENA countries.
