Examining the process
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

Heck, Paytan, Potts, and Haddad (2016b) talked about how this will affect the customers due to the processes being expensive, they must make up for the cost somewhere leading them to increase water rates and overall hurts the coastal region. He states that it hurts our costal region by limiting people's access to the ocean and causes a change in the scenery. Another disadvantage with continuing to build Reverse Osmosis (RO) plants using fossil fuels to operate them will lead to greater climate change and could make their droughts even worse in the future (Slocum, Haji, Trimble, & Ghaemsaidi, …show more content…
According to Gude, Nirmalakhandan, and Deng (2010) there are three different categories such as phase, non-phase, and hybrid processes and among each one of those three groups is a list of the different processes. Gude et al. (2010) explain the phase process as bringing the feed water to a boiling point and collecting the condensation as useable water and this process is used for multi-stage flashing distillation, solar distillation, or thermal vapor compression to list a few. Non- phase process is when salts are removed either from seawater or brackish water through the use of membrane technology and the desalination processes that use this technique is reverse osmosis or electrodialysis (Gude et al., 2010). He refers to the hybrid process as being a combination of the first two phases that can be used when doing membrane distillation or when adding multi- stage flash distillation or multi-effect distillation to the process of reverse osmosis. Another process used in California is called integrated pumped hydro reverse osmosis (IPHRO) process (Slocum, Haji, Trimble, Ferrara, & Ghaemsaidi, 2016). Slocum et al. (2016) talked about how this is the process of taking ocean water to use for both power and reverse osmosis, using the saline water to run the plant, and once filtered the water will go back to the sea or go back
Desalination technology converts the tons of seawater that cover’s California’s coast into drinkable water. This process, though expensive and difficult, would provide California with an endless supply of water. The ocean is a huge part of the California lifestyle, and it could become a huge source of their water supply too. The Groundwater Replenishment System recycles water to be used again. It takes in about seventy million gallons of waste water a day and puts it through a cleaning and purifying process, that then makes this water safe enough to drink. Many people may not be comfortable with drinking recycled water, but this water could be put to use in landscaping and farming, adding seventy million extra gallons a day. The desalination process may be a bit far fetched for now, but using a water recycling program is completely feasible and would be a huge help in reducing California’s use of water. (only its not reducing, its just providing them with more water to use yknow? how should I phrase that?)
It begins sea water to enter the sea water intakes through the refineries so as to prevent impurities from entering the sea water pumps, which in turn pumped seawater evaporators. After that, sea water mix with sodium hypochlorite when sea water intakes before entering the evaporator in order to process biological material sticking out. This solution (sol) is treated in tanks and then is injected through the pumps in specific amount on demand. There are electric power plates next to the sea water intakes for distribute electricity power that feed pumps and other electrically equipment’s, as there is also a measurement required for this equipment and control devices. The seawater moves
California should not desalinate Ocean water because it costs lots of money. This is true because in the article, “California tries one solution to water problems — treating seawater,” on page one it says, “The project is expected to cost $1 billion.” Also on page 2 it says, “San Diego County agreed to pay for 48,000 acre-feet of water from the plant every year whether it needs the water or not. It is doing so to ensure a guaranteed long-term supply. The water will cost $2,257 per acre-foot, about double the price of the authority’s most expensive supply now.” Lastly it on page 3 it says, “We believe in being innovative and open-minded when it comes to tackling the water crisis,” mayoral spokeswoman Marie Lloyd said. “At the same time, we do
Our big question was how did Egyptian artwork compare with China’s artwork. When we did this project I learned about Egyptian artwork and Chinese artwork, more deeply than before. Comparing them taught me that the Egyptians drew many pictures of the afterlife ( which they believed in very deeply), high officials in the afterlife and the gods. Like Horus and Isis, which was included in the Egyptian mural that I drew with Bushra. When it came to the Chinese mural I learned that China's artwork was more realistic more than Egyptian artwork when compared. They drew mostly the daily life of different social classes, like farmers, kings, merchants and other people. In our mural we drew the farmers of China harvesting crops for food and for
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
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
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.
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
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
California is having a drought and the Carlsbad plant thinks they have a way to fix this problem. Desalination is there solution to fix there drought in California . Desalination is when you take ocean water and take out the salt in the water. I don't think desalination is a good idea I believe that there are better ways to get drinking water.
Big scale desalination is a procedure through which sea water is pumped to a treatment office where the salt is extricated through a procedure of reverse osmosis to make the water fit for household use. San Diego County is at present developing the biggest desalination plant in the western side of the equator, at an expense of $1 billion. That plant, situated in Carlsbad, will give enough safe water to around 300,000 individuals, and will serve as a noteworthy test of the practicality and cost of utility-scale desalination innovation when it starts operation in November.
Desalination is the process of removing dissolved salts and minerals from seawater or brackish water. (WaterReuse, Association, “What is Desalination?”) A desalination plant essentially
There are three women in Chaucer’s Canterbury Tales, the prioress, the wife of Bath and the prostitute in the Shipman’s Tale. The prioress and the wife of Bath are the only ones of the three that have a fully developed part of the overall work. They are equal to the male characterizations; the prostitute is only minor player. Women are rarely mentioned in the other pilgrim’s tales. The wife of Bath and the Prioress are examples of strong medieval women. As Chaucer depicts them, they are a departure from the typical sinful daughters of Eve with the exception of the prostitute. The wife Dame Alisoun, and the prioress are both pious, successful females but they are still under the domain of men. Chaucer’s women are still part of the patriarchal world of the late middle ages.
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
America is a melting pot of cultures and races. I can proudly say that I am Hispanic. When I think of culture, I think of similar foods, hobbies, and traditions in a society. Our country adopts celebrations from all around the world. A specific example of a celebration that America has adopted is Día de los Muertos (Day of the Dead). Día de los Muertos is the remembrance of the loved ones who have died. American culture usually associates death with sadness and mourning, but Día de los Muertos is the opposite. The whole celebration lasts 3 days; October 31 is when it is said that the souls of all the children return to their loved ones, November 1 is when the children leave and the souls of the adults arrive, and they leave on November 2. There are festivals celebrated on November 2 all over Latin America. Although most of the United States does not celebrate Día de los Muertos, the hispanic communities are celebrating it and it is expanding.
