Process Intensification Of Sea Water Desalinatoin

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).

Ocean water desalination is the process of making ocean water drinkable. Seventy-one percent of the world is covered in ocean water, and a significant number of people in the world live within thirty miles of an ocean. Despite the abundance of resources, a large portion of the energy and materials found in the ocean remains largely untouched. Desalination of ocean water is the only solution for countries with a limited availability of existing sources of drinking. Areas such as parts of the Middle East and Africa, where water is scarce, may use outside shipments of fresh water and techniques to purify the abundant ocean water in order to survive. Some areas in South America where water may be abundant, could be unsafe to drink due to the biological

1. There are two main sources of fresh drinking water, ground water and surface water. Ground water originates from precipitations that usually fall in the form of snow or rain. While, the surface water is also originates from precipitate that reaches the land surface and is then recharged into rivers, wetlands and lakes. Although these systems are usually reliable, in desperate time of need, a more reliable source of water is needed. The desalination plant is extremely valuable and flexible because it does not depend on rainfall. Instead, the desalination plant is the only source that relies on seawater. Using seawater in the desalination plant helps meet the community’s water needs and secures the water needs in the future. While other sources of water, such as rainwater or water from dames are not reliable enough to strictly rely

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 .

The earth seems is drying up in certain areas of the world at the moment. We have already seen some of the hottest summers on record in the last decade. Summer 2016 was the hottest summer on record since the records were started back in 1880 (Doyle, 2016). The effects of this heat have manifested themselves as drought in areas of the western United States. One of those areas happens to be our home of Southern California. Water resources have slowly declined and conservation has been the key tool to battle the decline. In an effort to find new ways of conserving or creating fresh water supplies, technology has been called upon. The need for technology that can help us meet our fresh water demands becomes more important every day. One of the technologies that has gotten a lot of attention recently is desalination. In fact a large scale desalination plant was just opened in Carlsbad, Ca. The facility is capable of delivering 50 million gallons per day (MGD) (Bienkowski, 2015). Despite this impressive achievement the plant still only accounts for 8% of the total water demand in San Diego County (CDP, 2016). In this paper I will explain the process of desalination, identify a promising new technology, and provide a comparison of technologies.

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

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

There are many methods of desalination, however research shows that the most popular method is called multi-stage flash distillation (MSF), which accounted for 84% of desalination as of 2004 (Heimbuch, “How Desalination Works”).Multi-stage flash distillation uses energy from heat to evaporate salt water, and separate the water from the salt. This method of desalination can be very energy intensive, but fortunately multi-stage distillation can utilize solar power, making it a more environmentally friendly method of desalination. Other methods of desalination include forward osmosis distillation, reverse osmosis distillation, and low temperature thermal desalination (LTTD). The global need for more water in combination with emerging methods such as multi-stage flash distillation that utilize solar power, has the potential to evolve into a worldwide progression towards more environmentally friendly ways of

When nature limits our accessibility to water by droughts, we face no other choice but to turn toward the oceans for water. In that case we have to desalinate ocean water in order to purify it. The two most commonly known methods for desalination used around the world are Reverse Osmosis and Vapor Compression Desalination. We may take these two advancements in technology for granted in our daily lives and overuse the constantly flowing water. We need to take into consideration the amount of energy and effort required to purify water using these two processes. As the population grows in the drought areas the need for producing desalinated water is also going to increase, as

Due to the industrial revolution and the increasing in the world population, which leads to water scarcity of potable water and water for industrial applications. To cover the increasing demand of water we have to treat the polluted or saline water using the separation techniques to produce the potable and industrial water. This process it’s called, Water Desalination. Water Desalination is the process that treats the raw water by removing the suspended solids from the water. Sustain or the feed water sources may incorporate briny water or brackish water, seawater, ground water from wells, surface water (rivers and streams), wastewater, industrial feed and process waters. Desalination of seawater has the ability to produce enough amount of

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

The world is in a water crisis and needs more fresh water. Desalination can be an enormous help. The water crisis is the number one risk to the planet according to the World Economic Forum in January 2015. Our planet is 70% water but only 2.5% is freshwater, and we only have access 0.007%. The earth has 7 billion people who need water and 6.8 million struggle everyday for clean water. Today people even

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

Water is the nerve of life. It affects the food, energy, environment and health of billions of people living on the planet earth. Large populations living in vast arid areas around the world suffer from water scarcity. With exceedingly limited resources of water, about 200 million people distribute the Arab countries in North Africa, and the Middle East depends mainly on fossil groundwater that is a non-renewable resource. However, modern technology provides them a gift “Desalination” it is the technique of removing salt and other impurities from seawater in order to make it suitable for human use. This essay will discuss desalination as a necessary solution to water shortage in the future from various aspects such as sustainability, environment,

These risks provide that the desalination technology is not perfect now, and still has room to develop. The south of Australia is experiencing a long term drying trend, therefore the seawater desalination can be an integral part of base load supply in Olympic Dam Mine. However, desalination plants require a heavy investment and has impacts on environment, the Seawater desalination is becoming now one important tool to manage water supply in the dry places. Facing these challenges that ensure the coastal cities remain livable, the economies remain productive, and continuity mining process. For other Mines in Australia affected by drought, the seawater desalination is becoming a best way to solve the problem of water shortage.
