Salt Water Distiller A

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).

The first method, distillation, is the process of heating water to its boiling point, collecting the steam, and condensing the purified water vapor. The process is usually repeated a few times to ensure success in purification (Ocean Water Desalination). Distillation uses the property of higher boiling points in salts than in pure water. Possible contaminants that require removal for safe water consumption could include bacteria, lead, mercury, sodium, and chlorine. After boiling the water, water vapor moves through a series of tubes to a separate container where the heat source is removed, and the water is able to condense, now purified. Some strengths of distillation include the removal of heavy metals such as arsenic, lead and mercury, the removal of hardening agents such as calcium and phosphorus, and the removal of bacteria from water by heating. This elimination of bacteria is especially helpful in developing countries due to the increased risk of contamination because of unsanitary conditions. In this process, consideration needs to be given for adequate resources and infrastructure to deliver purified water to the general population of underdeveloped areas. A few disadvantages exist in that distillation does not remove chlorine and is relatively ineffective as the input is about five times the output (Water Treatment Alternatives -

My actual results and expected results were the same, my hypothesis was proven correct. Distiller A collected the most fresh water out of all the other distillers. This happened because Distiller A had the most surface area in direct sunlight, making the water evaporate more quickly than the other distillers.

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

With the unprecedented current levels of world population combined with generally high standards of living, humans are running up against the limits of available fresh water. Desalination is an increasingly important means to meet the water needs of people. Since there is so much more salt water in the world than fresh water, using reverse osmosis filtration is an effective means to get around the

By setting an amount of tests that would be conducted we allowed for an even number of tests between water temperatures. The amount of tests that were conducted were chosen with considerations, these included: the amount of time given to complete the experiment, the work force granted to complete the experiment and the equipment able to be supplied and used. This allowed for the optimal amount of tests to be conducted and allowed for accurate data collection. This experiment allowed for conclusions to be drawn and uses to be analysed. The use of this experiments results and conclusions in society are: allows for the optimal temperature to be chosen to purify water with the least time loss. This could be useful in survival situations and recreational activities, where time is

If the amount of sucrose increases, then the rate of osmosis will also increase. When distilled water is placed in a dialysis bag acting as a semipermeable membrane and placed into distilled water there should be no weight change because the concentration is balanced both inside and outside the bag. When a solution if 15%, 30% sucrose in a dialysis bag and that bag is placed into distilled water it should gain weight because the water will diffuse from a high concertation to a low concertation. But when distilled water is placed in a solution of 30% sucrose it should lose weight because the sucrose solution will diffuse into the distilled water because there is more concertation inside than outside of the bag. Diffusion is where a substance

My science fair project was turning salt water into drinakable healthy water. I wouldn’t be able to drink ocean water, because it would kill me. But I have discovered a good way to make salty ocean water safe and drinkable. You should know that the ocean covers 70 percent of Earth's surface, also nearly 97 percent of water in and on planet Earth is salt water (saline) there is so much ocean water on planet earth. Specifying on how much salt were actually dealing with, in the ocean water, the salinity of the water is about 35 parts per thousand. In other words, around 3.5 percent of the weight of water in the ocean comes from salts dissolving. The ocean is salty for two main reasons, Rain falls on the ground, and it contains dissolved CO2 (carbon Dioxide) from the

Given that the ocean holds 97.2% of Earth’s near-surface water, desalinization of seawater is the first option that comes to my mind that could be viable. Especially in arid and semi-arid areas including the Middle East, Persian Gulf, North Africa, Caribbean islands and etc., seawater desalination facilities can be “vital for economic development.” It can provide reliable and high-quality water supply to hot, dry, and increasingly populous regions and allow for local control of water resources at the same time. San Diego County is one of these regions, where county government decided to build a massive desalination facility that will be using the reverse osmosis with a cost of $1 billion. When it’s done, it is expected to produce 54 million

At this experiment is tried to apply a method how to improve the recollection of clear water from solar powered desalination plants, which it can be a solution for poor communities around the world in order to have more access to fresh water for human and animal use, as for watering purposes.

One reason for the opposing opinions is related to the socio-economic benefits of desalination. Seawater desalination contributes to economic and population growth and supplies fresh water to many of the water scarce countries. However, western countries still have enough alternative sources and the benefits of desalination will still be a privilege for richer countries. Even if desalination can be more cost-efficient than the overuse of natural resources, the high operation cost of desalination is a major problem for the poor

Seawater desalination plays a vital role in supplying sustainable source of potable water in different distinct and populated areas

In the past, we believed that a filter would sift out any and all impurities in a given water source. We didn't realize that separate filters were needed for different things. This lab exemplified how a filter works and what type of things can help to clean water. We believe that had we spent more time constructing the bottle filter, we would have received more positive results. To conclude, in some cases, the filters tested were able to clean certain contaminants from contaminated water. In the more polluted sources, it was evident that not all pollution was filtered out. It is highly unadvisable for anyone to conduct this experiment intent of drinking the

Abstract: Life on our planet requires fresh water. According to WHO, water scarcity affects roughly one-third of the world’s population, and approximately 2.3 billion people. The World Water Council states that this water crisis will become more acute over the next fifty years as the world population increases. Yet, water covers nearly three quarters of our planet -- 97.5% of this water is saltwater. Therefore, a practical, economically viable desalination process is crucial to overcoming this crisis. A number of seawater desalination technologies have been developed during the last several decades to augment the supply of water in arid regions of the world. Due to the constraints of high desalination costs, many countries are unable to afford these technologies as a fresh water resource. However, the steady increasing usage of seawater desalination has demonstrated that seawater desalination is a feasible water resource free from the variations in rainfall. A seawater desalination process separates saline seawater into two streams: a fresh water stream containing a low

This project revolves around design and fabrication of a solar distillation apparatus, which will give efficient distillation on a “round the clock” basis, and is capable of providing rural areas with pure and healthy drinking water supply.
