China 's Massive Population Pollution

Desalination is a great way to help people. Many areas do not have fresh water resources such as rivers and lakes. Taking out the salt from seawater will provide lots of people. This is needed where there is not a lot of natural drinking water. “People are building the Carlsbad desalination project. When it is completed, the huge plant will turn as many as 56 million gallons of seawater each day into drinking

A nation with a lot to lose. The huge, industrial and overpopulated country we know as China, is going through a water scarcity crisis. North China’s lack of water affects more of the region than anyone can imagine. Causing negative problems for food supply, economic development, political stability, and international relations, including drying up their major rivers. What are creating these complications? Global Warming, Urbanization and Population Growth, and Industrialization are the three main causes of China’s water crisis. Of these, the biggest driver is Industrialization.

In the face of a growing population, China has begun to use desalination techniques to provide ample clean water to its people and agricultural soils.

With the Pacific Ocean lining the California coast line some may ask why can’t sea water be filtered and used as a source of free water. This is actually an alternative that has been researched and even put into use in places such as the Netherlands, Aruba, the Middle East and even right here in the U.S. This process is called desalinating seawater. Saltwater in its pure form cannot be used for drinking water and is deadly to plants, however if it goes through the process of desalinating it can be used. With California desperate for water Carlsbad, California decided to construct a desalinating plant. An article on NBCNEWS website states that the plant can produce “50 million gallons of freshwater a day from the sea and pour it into a water system that serves 3.1 million people”

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

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

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

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

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 .

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 Water Plant is a water filtration plant that takes salt water from the ocean and turn it into fresh drinking water. Although the desalination process has been around for centuries, desalination plants allowing large-scale treatment of water didn 't come until the 1950s. In the year 2002, 12,500 desalination plants in 120 countries provided 14 million cubic meters per day of fresh drinking water (Ackerman, 2012).

A direct result of inattention to waste, the waters of China have become heavily polluted and toxic. In order for China to continue to prosper, additional regulations and their enforcement thereof must be put in place for the waters to be cleaned and rehabilitated to working condition. The drastic nature of China’s water condition is put into proportion by Jenifer and Jerry Mcbeath when they state that “water degradation… has reached crisis proportions” and “China’s water supply is 25% below the global average”. These poor conditions are a result of a multitude of regulation deficiencies, for example, those of factories, agriculture, and littering. Numerous industry manufacturing centers have been established on the coasts of rivers and waterways so that their waste may have easy disposal access, and the greatest amount of plastics runoff into the ocean is China’s. (Mcbeath and Mcbeath; “First… Waste”) If these issues are not regulated appropriately, the pollution will continue to increase and become further detrimental to all life in China. Already, countless areas of the ocean, rivers, and waterways are unusable or polluted as a result of the past abuses and lacking regulations. (Tibi; Moxley) In order for the waters to be restored, an organized system must be enforced for China to continue functioning.

The seawater used in most plants contain high amounts of two chemicals, called boron and bromide, and the process can also remove minerals like calcium. Also when they finished processing the salt out of the water, they put the salt left over back into the ocean, which the salinity affects the oceans environments. So, there are disadvantages and advantages to during the process, and there are even worse consequences if they run out of water. Concerns with the large amount of desalination plants in the Middle East focus on the improper dependency they will cause, instead of encouraging alternate forms of water and energy and conserving freshwater. Though they are lacking water, they have one resource they won't run out of for a while.
