Desalination Research Paper

The issue of building desalination plants has been a hot topic of Californians in the past couple decades because researchers knew that our available surface and groundwater supplies are becoming scarce. This problem is important because California is home to a large population of people as well as extensive agricultural and industrial productions that need vast amounts of water. With the reduction in available ground and fresh water brings other problems that need to be addressed. Many farmers are having to impose stricter management policies in regards to how they use the water the pay so much for. Crops sensitive to the amount of water they receive or do not receive can be destroyed in a short amount of time if neglected of water. With the amount of fresh water accumulated by both snow melt of California’s mountains as well as ground water retrieved from wells and pumps being depleted faster than we can recharge those sources, farmers face further impacts. An article by Robert Glennon, “Unquenchable: Americas water crisis and what to do about it” says “In the summer of 2009, California is facing mandatory water rationing. Many farmers may be entirely cut off, costing the economy more than $1 billion and putting more

To begin with many environmentalists will seek to block this bid owing to the concerns about the damage to marine life. There however, has been little evidence to suggest that a desalination plant will directly damage fish populations (Little). There are also concerns about the high cost of production and which stems in from its enormous energy demand and weighty environmental footprint; the massive energy requirements. The plant could be built adjacent to a power plant so they could share a symbiotic relationship and mitigate each other’s environmental impact. It is also very difficult to project the cost of the project owing to the nature of the plants. Different projects cost are virtually impossible to compare owing to their unique designs. These are concern by activists. Other blockades also claim that the project will take a long time to develop (Hiltzik). By this time they claim the drought will be long gone and it necessity will not be widely felt. All these are expected pitfalls in the process of getting a new plant in working in the state of California and will surely be

This is so because, in the article,“California tries one solution to water problems — treating seawater,”on page 2 it says, “Unless that intake is carefully designed, it can harm marine life. Reverse-osmosis filters are so fine that they allow only water to pass, everything else entering the desalination plant is killed.” Also on page 2 it says, “Carlsbad, for example, will use fish screens with tiny openings. These will strain out at least 95 percent of small fish, but only 20 percent of organisms. The remaining 80 percent of tiny organisms (including fish eggs) will be sucked into the desalination plant and killed. Many small life forms that fish depend on for food would be destroyed.” Also on page 2 it says, “The desalination industry worldwide largely favors screened intakes, despite the damage they cause. They are cheaper to build than the alternative favored by the water board (so-called subsurface intakes.)”This shows how because of the huge cost we are getting cheaper things that harm and even kill some marine

If residents and corporations throughout the United States continue to frivolously waste water and refuse to make painless changes and upgrades around their homes, it will continue to increase in cost to people across the United States. For example, as a result of the water shortage crisis currently afflicting the southwestern United States, the city of San Diego, California, is currently constructing a desalination plant, located in Carlsbad, California. The idea of a desalination plant is to collect undrinkable saltwater from the ocean and, using reverse osmosis and other filtering techniques, remove the salt to produce clean, potable water (Barnett). However, there are many downsides to relying on desalination practices to provide for a city the size of San Diego. First and foremost, it is considerably more expensive to produce clean drinking water from saltwater as opposed to using regular surface water or groundwater. The act of filtering the water alone can be twice as expensive as traditional filtration methods. In addition, desalination plants consume much more energy than traditional treatment plants, mostly due to the fact that the filtration methods are much more involved. Desalination consumes twice as much power as recycled plants, and four times as much as pumping groundwater (Newell, Roohk and Reardon). For example, the Carlsbad plant alone will require the same amount of electricity as is used to power 125,000 homes in California. However, the biggest

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 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 .

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

Water scarctiy is something that far too many coutries face. Everyday countries in Africa, the Middle East, India, and China face the detrimental challenges of not having enough water to provide to their population. Over the years there have been many propositions as to how we can help resolve this issue and restore countries access to clean water. However one process has remained. This is known as Water Desalination. Water Desalination is a process that was introduced many years ago to continents and countries located near the equator such as Africa, Asia, the Middle East, India, and China which are located on or near the solar belt. It has proven to help bring a substantial amount of clean water to these countries and to overall help deplinish

As world population increases along with demand for clean water desalination will become an increasingly important part of our water supply in the 21st century. We will not run out of water but we will pay more for receiving it in potable

Water desalination processes separate dissolved salts and other minerals from water. Feed water sources may include brackish, seawater, wells, surface (rivers and streams), wastewater, and industrial feed and process waters. Membrane separation requires driving forces including pressure (applied and vapor), electric potential, and concentration to overcome natural osmotic pressures and effectively force water through membrane processes. As such, the technology is energy intensive and research is continually evolving to improve efficiency and reduce energy consumption.

One of the significant drawbacks of desalination is that it is enormously vitality eager and costly at the tune of $2,000 a section of land foot, and there's something without

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

Water is a very essential component of living things on this world. It comprises three quarters of earth. We need fresh water for agriculture, drinking, medical and many other different purposes. But the renewable fresh water supply is less than 0.3% which is not enough [2]. It is really very hard to get fresh water for people who live near coastal areas to travel very long and get water for them. That is the reason why desalination came into existence where seawater is used as a source to produce potable water for use. The population grown bothered more for the demand of more fresh water. The fresh water resources like rivers, lakes are slowly getting lost or either getting salty [6]. There were several different approaches of desalinating the seawater to

Desalination is the process in which excess salt water and other minerals are removed from water to make it consumable (Rosadoi, Moraisii, 2010). This source of water is very expensive to operate in rural areas of Kenya because the materials and running cost is on the high side. It has a lot of environmental impact, positively it is an additional source of water supply and it helps to keep the groundwater aquifers from going dry however the side effect of desalination is that it leads to the emission of greenhouse gases, large production of concentrated brine, discharge of salt by-product which is harmful to people residing around. Water born diseases will be reduced drastically and also creates job opportunities due to large industrial plants for processing. Source of steady electricity power to make this plant work will be a major concern and a large number of inhabitants make lack the technological knowledge to operate the desalination plants.
