Summary:<\/i><\/b><\/p>\n

UN predicts that by 2050, 5 billion people around the world will be living in water-stressed areas. The need for better, economic and accessible technologies resurface each year with the increase in stress. One of the current solutions for providing freshwater, seawater desalination, even though effective, needs advancements that can make it more efficient and economic to be used for masses around the world. This article looks at heat composites as a possible solution in making the process effective and a polymer composite as a possible alternative. <\/span><\/i><\/p>\n

Description:<\/b><\/p>\n

Seawater desalination is basically differentiating salt and chemicals from seawater. It is the filtration process through which populations across the world get drinking water despite the low availability of freshwater resources. These plants which are all around the world, use one of the two major ways of desalinating water, Reverse Osmosis or Distillation. Where on one side reverse osmosis is far more advanced and effective, distillation is a traditional method that uses only energy as a major requirement.<\/span><\/p>\n

Reverse Osmosis<\/span><\/a> is a technique of pushing saline water through a semi-permeable membrane to get pure water on the other side. This requires a lot of work in terms of treatment of water, maintenance of membranes etc. Distillation, on the other hand, is a simple boiling of water to a point where the pure water vapors go up to the condensing chamber and thus giving streams of pure water. These are the two major types of seawater desalination that are being used all around the world and none of the other processes have proven to be close enough to filter a large quantity of water with effectiveness.<\/span><\/p>\n

Heat Composites for Seawater Desalination<\/b><\/p>\n

However, long back in 2012, another such process was recommended which involved heat composites. This method is used in some countries even today that includes Spain and Portugal. These countries face acute water shortage every year and so depend on seawater desalination to make water available. The method they use includes the planting of heat composite pipes in the desalination chambers. Here is how the process works. <\/span><\/p>\n

The Process<\/b><\/p>\n

Seawater is sprayed on the composite pipes which are made hot by passing hot gas or water through them. Because of the increased temperature, the water from the seawater is converted into vapor then sent in condensing chambers. What is left behind is a sludge of salts full of chemicals and unwanted substances. For this method to be effective, the pipes need to be strong and have properties that satisfy the points below:<\/span><\/p>\n
