Desalination
There are three methods of desalination which include, pressure, thermal, and electrical. Thermal desalination has been around since the stone ages, the water is boiled and the steam is eventually collect by leaving the salt behind. The use of an electrical fields to produce fresh water, this system uses far less energy than other methods. There's a certain phrase and technique in which they use that is called, electromechanically mediated seawater desalination. Pressure desalination also known as reverse osmosis desalination requires low pressures which in turn requires less energy. Although not widely used desalination of water could provide water by using thermal, pressure, and electrical methods.

The pump which the water is in slowly raises the pressure within the pump, then feeds the pretreated water through the membrane molecules. Once this happens steam is created, there will always be salt contents left over in the water, so the cycle is gone through several times. Once gone through these steps, the water requires Ph adjustments and degasification before being transported to the water plants to be served as drinking water.
Electrical methods are widely used in the desalination process. These plants use a very small electrical field which removes the salt from water, this method unlike many others doesn't need the membrane factor and in a microscale, which is highly liked in these methods since it is an easier and most efficient method. The electrical field forces the salt out of the water, and it requires fewer materials than any other method of desalination. In theory many people this is the most valuable method of desalination because it requires fewer materials, it is much quicker, and can be used it large

    Annually, Long Beach's port ships more than $180 million in trade, which means that this city is one of the wealthiest in the state of California.(Port of Long Beach). Therefore, even though desalinization is an expensive and energy consuming process, Long Beach's economic standing makes it one of the few cities in California that is actually capable of constructing a desalinization facility. Along with its wealthier economy, Long Beach its located on the Pacific coast of California, which also makes it an ideal location for a desalinization facility because this allows for direct access to the ocean and the salinated water supply that the facility requires. In October 2005, the Long Beach Seawater and Desalination Research and Development Facility was officially commissioned. It operated for four years as a research facility for a new technique for desalinization (Bradley). Half of the funding of the estimated $20 million project was from the federal government, and the other half came from state and local sources (Bradley). It was constructed on less than an acre at the Los Angeles Department of Water and Power's Haynes Power Plant in East Long Beach and at the time it was considered to be the largest of its kind in the…

    5. Salt kills the plants because the cells of plants contain water and many other dissolved substances. Since the water has a lower concentration, water molecules try to move the inside and outside the cell wall to equalize the concentration of dissolved substances in the cell, which is called osmosis. Water molecules will be sucked out of the cell by a high concentration of salt, and resultingly it causes the plants to dehydrate due to an osmosis.…

    Water is separated into hydrogen gas by pulling off the oxygen atoms. It can then be burned like any other gas such as propane. It can also power an electric type engine by exposing the hydrogen to oxygen, because the hydrogen wants to reattach to it and make water again. As the electrons shoot around, the electricity is harnessed and it runs like an electric car, and the exhaust pipe lets out a few drops of pure water.…

    With these solutions, water can be conserved efficiently because for the first method, it’s easy enough to do as an individual. Also for the second method which were about “shade balls”, it will make a great difference in saving water because if it didn’t exist, then the droughts would’ve gotten worse making it harder to live in those conditions. And finally for desalination, it is a great method for giving access to clean water. These methods have shown that if used, then the water that is left in our world may actually be saved if we took it to our…

    On the other hand, a contrary position could be the claim that a larger number of people would be happy with the exploitation of the oceans as water resources because it could help millions of already-struggling individuals. This is a strong opinion shared by scientist and politicians alike; however, it has a few logical flaws if analyzed with rule utilitarianism. Firstly, humans are not the only species affected by desalination, and the pain caused to the millions of aquatic organisms, and others who depend on them, must also be measured. Thus, considering the happiness or suffering of hundreds of species affected helps shifting the balance against decisions which damage the environment. In the same manner, the life of the next generations can also be considered a limitation, for long-term consequences of desalination are already predicted to be harmful. Ultimately, an environmentally conscious approach would bring the most pleasure for the people to come.…

    In the whole world we have 5 giant oceans. That’s 326 million cubic miles, that amount of water can last us a very long time. The only problem is we cannot just drink salty water like that because for humans it is extremely hard for our bodies to take in all of the sodium. That is why we have to purify it. Although the whole process of water desalination is expensive and time consuming it is definitely worth it because we need water in everyday life. Other than the cost the only negative thing about water desalination is that it can cause climate change. But, that one thing is not really a big deal considering we have all of the other ways to get water on top of water…

    In this experiment diffusion and osmosis is the main idea. When using diffusion and osmosis you are trying to separate different solute concentrations on either side of the membrane. Only a solute's relative concentration, or water potential, affects the rate of osmosis. The higher the concentration of solutes, the faster water will flow through the membrane to equalize the concentration. The way we describe the movement from higher to lower concentration or lower to higher concentration is called hypotonic solution and hypertonic solution.…
