Desalination Process

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?)

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.

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

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

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

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

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 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.

Although water desalination was introduced and has helped many countries in aleviating their scarce water supply, the process itself is steadily decreasing in use due to the extreme cost it takes to run each and every desalination plant in these countries. The technology, machinery, and fossil fuels being used are far to expensive to continue using desalination as a method of providing water to countries in need. For this reason it is necessary that solar energy and forward osmosis be introduced into the desalination plants for the simple reason of being able to save countries fossil fuels and money. With these two new sources of energy being implemented into the plants, the water that is filtrated through the desalination process will be more efficiently spread throughout countries that are located all throughout the solar

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

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 of sea and brackish water is a common technique to alleviate the increasing shortage of fresh water in many areas of the world today. Nonetheless, desalination processes require large quantities of energy. In addition, the cost of the different desalination techniques is very closely linked to the costs of energy. Therefore, in a context of continuously rising energy costs and with the impending exhaustion of the conventional energy resources, the development of energy- efficient desalination technologies is a very attractive and promising prospect to solve these problems.

Desalination 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 following steps explained by Eco Chem “Step 1. Seawater enters the desalination plant through an intake system about 300 meters offshore. Water enters at a low speed to avoid impacts on marine life. Step 2. Seawater passes through an initial screening to remove any debris. Step 3. Seawater is filtered to remove any fine particles. Step 4. Filtered seawater passes through the reverse osmosis membranes Step 5. Desalinated water is treated to meet strict Australian Water Guidelines. Step 6. Drinking water is pumped into the water distribution network. Step 7. Seawater concentrate is safely discharged to the ocean and dispersed through outlet diffusers about 300 meters offshore.” The steps of desalination are a very difficult and tedious task, which can be problematic.
